Subwoofer in Ford Focus 2

The subwoofer in the Ford Focus 2 is designed to significantly improve the performance of the built-in speaker system. The Ford Focus 2 stealth subwoofer or a speaker in a different design will enrich the sound with bass, which is so lacking for an understanding car audio lover.

A general look at the problem of connecting a subwoofer and speakers in Ford Focus 2

How to connect a subwoofer Ford Focus 2

Let's start with the fact that many "focus guides" want to leave the old car radio and acoustics, simply adding and integrating a subwoofer with them, feeding all the speakers through an amplifier.

To realize such aspirations, you can go in 2 ways:

  • Solder the line connectors from the standard device, which will cost about 3 thousand rubles;
  • Install a divider on the high-level outputs.

The first option is considered as the most correct, since the car radio amplifier is excluded from the general system (see Car radio power amplifier microcircuit and a practical description of its operation), and the sound quality does not suffer from this. For him now in the answer external amplifier.

Note. Although the preamplifier still remains in operation, in this case it is considered the least evil of a standard device.

Installing a subwoofer in a Ford Focus 2

The second option leaves the amplifier in operation. He introduces the corresponding distortion in the path. This option involves connecting a subwoofer and changing the standard acoustics to speakers of greater power.

To enable the second option, do the following:

  • stock up standard set: buffer, amplifier, wires and 2 dividers;
  • Dismantle the standard device by inserting removable keys;
  • Unhook the standard connector from the car radio;

  • Set the amplifier so that it turns on simultaneously with the ignition;
  • The power cable is driven from the battery;
  • We put the dividers to the Sony output, having cut the wires in advance;
  • We put the amplifier in the luggage compartment to the shelf.

AT this moment the cost of such an adapter is 2900 r. Select FRD2 in the catalog. Scheme connections linear…

Note. In Ford Focus 2, the shelf itself is not even. Therefore, it is recommended to make a plywood spacer and cover it with a black carpet.

  • We fix the amplifier to the spacer and carefully connect the cables;
  • Plug in the sub and enjoy.

Choosing a place for a sub

Subwoofer ford 2

This issue should be given the most attention, since there may be several installation options in the Ford Focus 2.

Every motorist dreams of driving with a breeze to the bewitching basses of his favorite rock composition. But ordinary acoustics will not be enough for this, namely, it will not give volumetric sound, its depth, which can only be provided by a high-quality subwoofer.

It would seem that this question is clear, a subwoofer is necessary, but for some reason, most motorists simply cannot imagine where such a speaker can be mounted, which gives the maximum efficiency of the entire speaker system.

So, let's look at everything in more detail:

  • To begin with, let's say that they are used in cars different types acoustic design. In principle, there are four of them, as the main ones, and the option called “free air” is more popular.

Note. Note that the use of a complex speaker for the woofer makes it possible to install an amplifier with less power. At the same time, the sound quality and volume will remain at the same level. Considering that the price of an amplifier largely depends on its power, this aspect is extremely important.

  • When choosing a subwoofer, you must first pay attention to the number of voice coils. The more coils a woofer has, the less amplifier power can be, again;
  • The most popular are active subwoofers sold with built-in amplifiers. In this case, the task of the motorist is noticeably simplified.

Multiple installation options

So, where can a motorist put a purchased sub:

  • The first option, which is considered the simplest and most suitable for sedans, involves installation in the rear acoustic shelf. This method for Ford Focus 2 it will not work and the speaker must be selected with a special woofer head;
  • Installation in the armrest in the rear seat. This option basically good. It is often used by music lovers. The principle is the same as when installing in the rear shelf, although there are some nuances.

Note. With this installation, care must be taken to ensure that the holes are of sufficient size and do not have a negative effect on the woofer cone. Otherwise, there are no special requirements, except that it will be useful to construct a well-insulated wall behind the back of the sofa.

  • The most ideal option for hatchbacks is a stealth type installation. In other words, the speaker is placed in such a way as to take up as little space as possible. It can be mounted in the outer niches of the luggage compartment or under the spare tire.

It turns out that you can install a sub in Ford Focus 2 with your own hands, without any problems, if you know all the intricacies of the process and use competent instructions. Video and photo materials can provide invaluable assistance. The price of modern subwoofers is different. It all depends on specific model, but saving on this speaker is not recommended.

Real music lovers prefer to enjoy high-quality sound both at home and while driving. To listen to your favorite music in excellent quality, upgrade the speaker system (AC). A pumped speaker consists of: a head unit, an amplifier, a subwoofer and speakers. A subwoofer helps to get surround sound. In this article, we will consider the selection and installation of a low-frequency (LF).

Passive and active subwoofer: differences and features

You have decided to install a complete sound system in your car. The first question that has to be decided before buying is the choice between a passive and active subwoofer. Let's give a little educational program.

The passive subwoofer has a simple design. This is a case and one speaker or several low frequency audio heads. It is desirable to connect such a sub through an amplifier.

There are two ways to install a subwoofer in a car audio system without an amplifier: directly or with separation filter. The second allows you to get a cleaner sound, without distortion. Using this method, many save money, but such a connection does not give good sound and can lead to a short circuit and failure of the radio, speakers or subwoofer.

An active subwoofer is a combination of several devices in one housing. Its design includes:

  • audio sound amplifier;
  • frequency separator;
  • woofers.

On the body are placed line inputs and outputs, audio power controls and frequency splitters.

An active sub is easier to set up. By using default settings get good bass. A passive subwoofer requires an external amplifier. Setting up a passive woofer is hard work. But the result will exceed all expectations. Real music lovers achieve the best sound with passive subwoofers. Active costs 2-3 times more than passive. But the latter only works well with an amplifier that is bought separately. As a result, we get approximately the same amount of costs.

Wiring diagrams

The process of connecting a subwoofer and speakers in a car is rarely difficult. The instructions below will help you install and connect correctly.

Passive

Passive bass is recommended to be connected through a sound amplifier. It has connectors for connecting a subwoofer. For switching use special acoustic wires. They come with a sub. If they are not, then we buy the required length in a specialized store or on the radio market. At the ends there should be RCA connectors (like "tulip").

In the absence of an amplifier, a passive subwoofer is connected to the front speakers. The sound will become more voluminous, but it is difficult to call it quality. A low-pass filter will help to correct the situation. It feeds sound to a passive subwoofer. The task of the filter is to suppress the high-frequency component sound signal and apply only bass to the sub. Such a device is sold in stores. But if you have the skills and ability to hold a soldering iron in your hands, then it is not difficult to assemble the filter yourself. In specialized literature and on the Internet, circuit diagrams devices.

The signal from the head unit goes to the amplifier, and from it is distributed to the speakers and subwoofer

Active

An active subwoofer does not require the use of an amplifier. Its body contains an additional module for amplifying the sound and frequency controls for fine tuning.

On modern car radios There is a line out for connecting a subwoofer. It is connected to the input of an active subwoofer using an acoustic cable. Another wire is for subwoofer control. It is designated as REM or System Remote Control. The cross section of the control wire is not critical, a weak current flows through it.


Active sub connected directly to head unit. The power to the subwoofer is falling off battery car

Separately, to power the active subwoofer, a power wire is laid from the battery. Be sure to install a fuse in the power circuit of the amplifier and the active subwoofer. It protects the speaker system from short circuit.

We connect the sub: important points and instructions

Let's analyze the process of installing a subwoofer in a car with a connection to a head unit. Before starting work, pay attention to a few points:

  1. The subwoofer enclosure and the amplifier itself are overall devices. We need to think about where to place them. Most often, they allocate space in the luggage compartment of the car.

    The amplifier, if possible, is placed on the back of the rear sofa. Please note that the amplifier and powered subwoofer will become hot during operation. These devices require good cooling. Position the amplifier and sub so that air can circulate freely around the devices.

  2. If regular head device does not have outputs for connecting a subwoofer and there is no control wire, then consider replacing the radio. This will protect against a possible short circuit, simplify the connection of the subwoofer and allow you to get high-quality sound. An active woofer requires battery power. The power cable must be of the appropriate length and section. Consider where to lay it from the engine compartment to the luggage compartment. It must be firmly fixed with plastic clamps.
  3. Check for a subwoofer line-out on the head unit. If not, there is a way out. The subwoofer is connected to the speakers or the AUX output. This solution is not ideal and affects the sound quality.
  4. The System Remote Control wire is required to control a powered subwoofer. Without it, the amplifier module does not work. If there is no such output in the radio, then you can directly apply constant +12 volts to the input of an active subwoofer. With this connection, the amplifier operates continuously and discharges the battery.

Necessary tools and materials

To successfully connect a subwoofer with your own hands, prepare the following tools and materials:

  • wire cutters;
  • a set of open-end wrenches;
  • insulating tape;
  • pliers;
  • plastic ties;
  • power cable;
  • acoustic cables;
  • 60A fuse in case;
  • plastic pullers for dismantling the trim elements.

The length of the wire for powering the subwoofer and speaker cable depends on the specific car model and the possibility of laying wiring under the skin. The cross section of the power cable depends on the power of the active subwoofer or amplifier. For example, the power of the subwoofer is 200 watts, divided by 12 (the voltage value in electrical circuit car), we get 16.7 amperes. Such a current must withstand the power cable and not overheat. Based on this, the wire section is selected.

Step-by-step instructions for installing an active subwoofer

  1. Turn off the car, remove the terminals from the battery.
  2. Route the power cable from the battery to the subwoofer installation site. The wire must not fall under the pedals or interfere with the operation of other mechanisms..
  3. Install a fuse on the wire near the battery. Do not connect the power cable to the battery terminal.
    The subwoofer is powered by a rechargeable battery. Be sure to use a fuse to avoid wiring trouble
  4. Remove the head unit and inspect the rear panel. Locate the line output for the subwoofer and the control wire.
    We find the line output for the subwoofer and the control wire
  5. Route speaker cables and REM (System Remote Control) wire from the radio to the subwoofer location. Place the wires under the trim elements and securely fix them with plastic clamps.
    All wiring is laid under the trim elements of the car. It is securely fastened with plastic clamps.
  6. Connect the control wire, speaker cable, power and ground wires to the subwoofer. "Earth" take from the metal surface of the car body.
  7. Connect the subwoofer and the REM wire to the radio. Carefully insulate the twisting points. Install the radio in its original location.
  8. Connect the power cable to the "+" terminal of the battery.

Video: The easiest way to connect an active subwoofer

Watch the video for details and installation sequence. Perhaps it will help you evaluate your strengths and get an answer to the question: who will upgrade your car's speaker system?

Nuances of installation in cars of different brands

The subwoofer and amplifier are placed in the luggage compartment in 99% of cases. But the trunk does not always have sufficient volume. For example, in the VAZ 2114 it is problematic to place a passive subwoofer and an amplifier and leave room for transporting something. Therefore, for 2114 it is better to choose an active subwoofer with a suitable enclosure. Fortunately, car audio stores offer a wide selection of models of different capacities and configurations.

Take the laying of the power cable seriously. Find a way to bring the power wire through the factory holes. To pass from the engine compartment and into the luggage compartment, use rubber or plastic couplings. The wire must not come into contact with metal. This will help protect it from chafing and possible short circuits.


For the power cable, it is recommended to use plastic or rubber sleeves for transition from the engine compartment to the passenger compartment and from the passenger compartment to the luggage compartment

Self installation and connecting a subwoofer will take from 1.5 to 3 hours. The procedure is simple, but requires care and accuracy. If in doubt, contact the installation specialists acoustic systems. They will pick up the AC components and connect them. And after 2-3 hours you will be able to enjoy high-quality surround sound in the car.

Greetings to all readers of my review. I am posting a slightly belated summer post about installing a subwoofer in the “blue kettle”, as well as its further connection to the head unit.

Let's start with some theory:

In an ideal scheme, to install a subwoofer in a car, you must:

1) A radio tape recorder with an output for sub - tulips and a separate equalizer adjustment;

2) The subwoofer itself, a set of audio and power wires, as well as a fuse.

Since my car has a full-time restyling radio tape recorder, with an already built-in amplifier, and there is no desire to change it, as well as the presence of low outputs in it, there are two options left:

1) Buy a device, the so-called "High-low Impedance Adapter", which is hung on a pair of speakers, usually on the rear ones and cuts all frequencies except low ones. Well, and further from it tulips stretch to the amplifier. And then the passive subwoofer clings to the amplifier.

2) Use an active subwoofer with a “High Imput” input, which will allow you to directly feed the signal from the speakers to it without conversion.

Initially, I wanted to install a regular subwoofer in the rear shelf from older versions of the chaser. I have already bought a set of a radio with a screen (without a built-in amplifier), a native remote amplifier that lives under the passenger seat, the pancake itself, as well as a grid in the shelf to match the color of my cabin. But transport company I decided to play football with a parcel. As a result, a drip formed at the radio in the corner of the screen, and the standard amplifier turned out to be burned when testing the assembled kit. Disappointed by this result, there was no desire to order a second set, but an active subwoofer Mystery MTB-300A of impressive size (width 380 height 375 length 600) mm was at hand. For lack of any other choice, it was decided to put it.

Mystery MTB-300A

Since I am not a fan of cutting standard wiring and I try to do each installation with high quality and with the ability to turn it off and bring it to stock, it was decided to buy two Toyota - ISO, ISO - Toyota adapters. In order to make a branch from the speakers in the future on the basis of this bundle of an adapter - an extension cord:

Toyota-ISO adapter

ISO-Toyota adapter

So, we need to take the regular signal from the rear speakers, as well as the signal from the ACC ignition to activate the subwoofer (aka Remote cable). According to the scheme, we take these wires LR +, RR +, LR-. RR- and ACC from the adapter and build wires on them.:

TOYOTA CHASER head unit pinout

In order not to look for wires and not to collect them piece by piece, I bought an installation kit of wires from AURA AMP-2208. It already has everything you need.

The only thing that I bought separately is a corrugation, for additional protection wires, as well as more aesthetic appearance. As a result, after soldering and weaving the braid, we get the following result:

Woven braid with adapter - extension

The only thing left to do is to test, and then lay the power cable, along with the newly woven audio braid. In a chaser, it is best to run cables along the left (passenger side) threshold. It is also easier on the left to thread the power cable from under the hood into the passenger compartment, there is a rubber plug. I used wire and the power cable itself to push it from under the hood into the passenger compartment. The stove did not have to be dismantled - everything worked out and so. In the future, the threshold is disassembled, the carpet rises and the back sofa is removed - for pulling new cables. Having done the above and connected the subwoofer's power supply, according to the diagram in the instructions, we get the result we need.

Despite even the impressive size of the subwoofer, I did not think that he would be able to pump the interior. since in front of him is a solid metal back behind the sofa, as well as a fuel tank. But the result exceeded my expectations. This buzzing sounds great even on the lowest settings. Since I am not a fan of overly strong bass, but in music I like a good balance between medium, low and high frequencies, the radio was set up as follows: BAS +3, TRE +2. On the sub itself, I set the twists like this:

MTB-300A settings

The whole operation took half a day, the result is considered successful.

I decided to add low frequencies to my car. I bought an active subwoofer FLI FU12A 1000V - for a start it will go. Now I’ll tell you in more detail about pulling cables, because as I ran into it myself, I couldn’t really find anything.

1. If there is a multi-level input (HI-INPUT) in the sub, then connect to it, and not through tulips - due to ignorance, I connected first through tulips - after that there was an engine background in the sub with the sound turned off, and through the multi-level channel the sound quality is much higher if the connection goes to the native radio!

3. Refinement of the subwoofer enclosure in the Ford Focus 3

I didn’t have enough bass in the car, and the head was gathering dust in the closet, since no money was expected to create the right stealth in the near future, it was decided to install a regular box temporarily. Why was purchased a box with a volume of 22 liters.
As I did not try to calculate it in JBL Speakershop, to create an even frequency response, I got from 18 to 22 liters for my speaker. In an article testing my speaker in AVTOZVUK magazine, there was another "ideal volume for my speaker, namely 26 liters. But I had already purchased a case by that time, so it was too late.
As a result, the internal volume of the box turned out to be 22-2.6 = 19.4 liters.
The case is assembled quite qualitatively, although not without flaws, which we have to correct. The first is the cable from the port to the speaker

14:1425

The wire was replaced with 4 sq. mm. DAXX OFC needed 2 meters at 197 rubles per meter.
Next, I decided to make it airtight, because. he did not inspire confidence in me, and the first thing I started sealing with was the port, by the way, also of obscene quality, when taken out, it cracked and broke. The quality of the plastic is disgusting. Therefore, it was decided to buy more decently for 220 rubles in Audiomania.

28:1309

I don't know if it's visible or not.

28:1352

After that, the speaker was glued with the same sealant and screwed with self-tapping screws.
I forgot to take the final photo.
Setting up this whole thing took about an hour last night and about an hour this morning. I managed to achieve the sound I wanted, but in the end I still had to compromise due to the fact that my front speakers were apparently dying. An excellent bonus was the fact that the box was sculpted from the Ford campaign, because. to the back sofa, he stood like a glove.
It plays perfectly, the bass is deep, musical, it hits the ears where necessary.
There was a big question for the installation studio that installed the amplifiers. There are no complaints about the front amplifier, but the subwoofer falls off to protect against overheating and a couple of times from a heavy load, but I have already corrected this jamb.

I watched a lot of ready-made boxes with dynamos, tried on a lot of things in the car, but I didn’t like something. The goal was 2 din and take the floor so small trunk. As a result, I came across a good idea here on the drive, it was in the ff3 hatchback that the size questions were not successful. As a result, a box with similar dimensions was calculated, but with a different hole (it hammers very hard).

I didn't like the sound, much to my regret. Having smoked the forums, I realized that it was possible to glue cotton wool inside, but there was no cotton wool. Shumka glued Comfort Mat Bibiton 8 mm. As I glued it, I tested it and was very surprised, the sound changed a lot, it became deeper and better.
