Benefit from powerful, dynamic and tight bass
The IBus 2.1 subwoofer has a compact aluminium chassis. It is very sturdy and has a low profile, allowing for good heat dissipation.

Compact, practical, powerful and easy to install, the IBus 2.1 subwoofer is not lacking in assets. It has a remote control that allows you to keep control at all times, but also high level inputs that allow you to keep an original car radio.
Focal offers you the ideal solution for achieving impeccable sound quality in your vehicle while preserving the interior aesthetics of your car.
Main features :
20 cm flat amplified subwoofer 75 W RMS
Compact aluminium chassis
2 channel amplifier, 2 x 55W RMS
ISO plug & play cable included
Easily integrated under the seat
Reinforces the bass of your audio system
Powerful amplification solution, allowing you to keep the ergonomics of your original source without losing the display and control functions
Plug and play harness, but not for Vw, so 4 stars, shame, the adapter is still 50 €. I have modified my speaker system. I've modified my speaker system, quite a lot of adjustment, good sound quality, remote control with potar and 5 meters of cable, to place where you want it near the driver for more bass. The ibus 2.1 is fixed in the trunk on the seat, because no space under the seats (Scirocco) connect without RCA but with the focal beam, so no need to pull the remote to turn on the amp, it detects the ignition by the signal of the speakers. All the cables are supplied with it, you just have to take the car apart. Enjoy.

Very good product.
Good bass and sound improvement too. Not so easy to fit under the seats of newer cars with all the sensors underneath. Installation is simple, you just have to find the right connection to the vehicle. Afterwards, the connection to the car radio is more or less difficult depending on the type of car. Otherwise the IBUS 2.1 is not complicated, you just have to find the right place for it. The hardest thing is to find the right basic setting and to refine it to your ear, it takes time, but the result is worth it.

Very good value for money
Installed in my Citroën Saxo (2003), with a pioneer car radio, and 2 pioneer 3 way front speakers. In addition to having bass, the integrated amplifier clearly improves the quality of the sound on the front speakers (hence the 2.1: 2 front speakers + 1 subwoofer), so be careful, if you have 4 speakers or more in your car, only the two in front will be amplified! If not, you have to connect the subwoofer to another amplifier, or to your car radio if it has an output for this purpose (so quite versatile in the end).
For the installation, be careful! Even if it is a "plug and play", inform you well on the connectors of your car radio and your car, because it is possible that you should buy an adapter, or cut cables and reconnect them manually to be able to install the box. I just had to cut and reconnect a cable as my ISO connector was old and didn't match the one on the subwoofer.
I had a lot of trouble installing the box (due to my crappy ISO connector), so here's a little help if it can help some people: You have to connect the (+) to the battery, and the (-) to the ground (on a screw or on the body, but you have to scrape the paint to have contact! ). Then, connect the "remote" cable which allows the ignition of the box thanks to the car radio (that's why you have to check your ISO plugs, or the car radio of your car). Finally, plug and play or RCA depending on what you want as I explained above. I had to select a source on my car radio because if I stay on the first menu, the "remote" is not activated, and therefore the box does not turn on.
I've been using it for a while now, but it's a good value for money, clearly improves the sound, lots of settings, made for "small" equipment, and a bit of a pain in the ass to install for me.

generally satisfied
The subwoofer improves the sound quality in the car and allows a separate amplifier for the front speakers, all this in a minimum of space. On a Peugeot 3008 serie 2 it does not go under the seat because of the air conditioning for the rear passengers. It can however be installed at the rear of the driver or passenger seat provided that it is protected.The Ibus received originally had a difference in the amplification level of the right and left speakers in the low gains which indicates a bad end of chane control unless the defect appeared later which is also possible. The unit was replaced quickly and without problems under warranty during the holiday season.

Good side cabinet
I recommend this box for its size, build quality and sound quality; placed under my boot floor (almost invisible).
It adds the bass that a 2-way system lacks at a reasonable cost.
There is quite a bit of adjustment via the built-in amp.
I opted for the supplied cables (high level) and not RCA for ease of connection to my car radio (which is not original).
I'm not sure if I'll be able to use it in the future, but I'm sure I'll be able to use it in the future, and I'm sure I'll be able to use it in the future, and I'm sure I'll be able to use it in the future.
Be careful with the size of the cables which are quite short; they can reach the boot of some city cars. It is advisable to put it under the seat for compact cars, sedans or SUVs.
Don't expect to blow out the windows of your car, the box is only 150W max (75w rms), enough for me.

Mitigated
Suitable if the original installation is really bad. Otherwise the sound is not bad but it's not crazy. The cabinet reaches its limits very quickly and the integrated amp sounds like a boil (normal, it's a class D and not a class AB). In short, it is loud and the sound is correct. I don't understand these diterambic notes. Prefer the version without additional amplifier Ibus20. Obviously, Focal is positioned on the entry level.
