Review: Pow! This much bass for so little money - This is a quality bit of kit. If you want to suppliment your factory installed system or you only have a small car, this is the sub for you. You don't need pre-outs, so you can keep your factory head unit and connect this up to the rear speakers. It has a built in line out converter. So its a total package, no seperate amplifier or LOC needed. The remote makes it really easy to adjust the bass to suit the song or your mood without having to fiddle with settings on an amp or your head unit. Power wire really needs to be attached to your battery. It can be awkward to route the wire through your firewall and into the engine bay. I used the existing rubber grommet for the main wiring loom behind the glove box. It was awkward, but I got the wire through using a thin stiff piece of wire threaded through, taping the power wire to the end and pulling it through. You also need to attach a wire to a switched 12V feed when the head unit is on, so a multimeter really comes in handy to find the wire you need. You get all the wires with the unit, so you shouldn't need to buy anything else. I recommend soldering the wires where required so you get a good permanent connection. I soldered the ignition/stereo live and the rear speaker connections. If you self install, there are a few video's online that can give you some tips. I bought this as a 'open box' special for £85 and its well worth its money.
Review: Powerful sound, tricky installation - I recently purchased this in-Car Subwoofer and I am impressed with its powerful sound and overall quality. However, I must say that the installation process was a bit tricky, despite the fact that the product did come with everything that was needed. The subwoofer produces deep, resonant bass that adds an incredible dimension to any music played in the car. It is well-constructed with sturdy materials, which ensures that it can withstand the vibrations and bumps associated with driving. However, I did encounter some difficulties during the installation process. Although the product included all the necessary components and wiring, it took some effort and time to correctly connect everything. This may not be an issue for experienced car audio enthusiasts, but it could pose a challenge for those with less experience. That being said, I was ultimately able to install the subwoofer correctly and the resulting sound was worth the effort. The powerful bass adds a new level of depth and richness to my music listening experience in the car.

## Questions & Answers

**Q: I have one of them....but need the wiring for it do you sale them**
A: I am sorry but spare wiring is not available from Alpine.

**Q: Someone tried it on peugeot 307? They say this car sucks for music?**
A: Doesn’t matter what car you test it on properly fitted it’s AMAZING

**Q: Can you route 2 subs into 1 controller?**
A: Probably but why?   Just get the 12

**Q: Does this fit in any car? Does it come with a wiring kit?**
A: Yes, as long as the car is big enough. Be careful who you buy these from though as some sellers like marcomeggio82 are not honest about the taxes which should be included in the price you pay. They may insist that you pay 20% more tax to HMRC if you are n the UK when your item is stuck at customs or with the courier. Took me over a month to get my money refunded from Amazon because the guy was so rude and unhelpful. Personally I'd never buy from a marketplace seller ever again. I also dislike liars intensely.

### ⭐⭐⭐⭐⭐ Very pleased
*by E***K on 25 April 2025*

Installed this in my vw polo. More than enough for the small car. Speaker definitely packs a punch. Very simple to install. Just have to run some wires through the interior trim. Very strong good bass. Makes a huge difference. Recommend this to everyone looking for a first time sound system upgrade in their vehicle. Worth the price tag .
