+ Great Sound, Great Quality, Easy to Install, Fantastic Value.- No RCA Leads.This is a great little sub if you’re after a fuller sound for your car. I installed a set of component speakers into a Kangoo van and was disappointed with the bass, so I fitted this and it’s made a massive difference! It’s a substantial well built item and has all the sound controls on the remote instead of fiddly dials on the back of the unit which makes it great to tune while it’s situ without messing around accessing it again. It comes with all the leads you need to get it running via high level input, but you will need to but a phono lead if you want to connect it via low level RCA.

For the price I can't complain. This does the job if you want to add a little low end and space is limited. It's not too difficult to install if you understand basic wiring. The sound quality isn't audiophile but it will improve any standard set up that lacks the low end. It has an adjustable crossover and gain controls on the unit itself, and an additional remote volume control. What's more it fits neatly under most car seats. You don't need to buy any additional equipment to get this going, all the wiring is also provided. Ok so maybe the bass isn't very tight, it's not going to compare to a 12 inch sub box booming insane levels of bass in your boot but it's an underseat space saving 6" woofer with a built-in amp (active) for less than £150, it is a massive improvement to standard car speakers.Personally I dial the crossover from my head unit (car stereo) as it has a sub out, this will give better results but you can use your factory stereo and wire in using the speaker connections on the back.It's never going to compete with a proper sub but it's nice and compact and provides the extra bass I was missing without breaking the bank.Edit: I've been using this unit for a while now and no complaints. I actually take the longer way home so I can enjoy the music 🎶

really good sub for the price, plenty of bass and easy to setup. fits under car seat perfectly. remote included is good to tune bass levels.recommended 👍🏻

This sub is incredibly solidly built, the case being die-cast aluminium. It easily slipped under the passenger seat of my son’s Aygo (mk1), and held in place ok with some Velcro pads (not supplied) rather than trying to screw it down. The kit is complete with cables for many different types of installation and the instructions are very clear. We did have one installation issue that arose because we also changed out the Argo’s old CD player head unit for a more modern Pioneer one with bluetooth hands-free; The adapter that came with the radio had to have its yellow (permanent 12v) and red (switched 12v) cables crossed over as the subwoofer was not powering up correctly (and yes, the blue/white remote device wire was correctly installed!). After this, it was plain sailing to hide the wires under the central console without having to remove any seats for access. The result is a stereo with MUCH better bass that’s audible at even motorway cruising speeds. A very simple and very useful upgrade to the Aygo.

Item not a 12 inch monster but I absolutely adds to the low end and improves the quality of the music! Fitted under the passenger seat of a 2001 sprinter. Very happy to recommend it.

The 2 way speakers in my Ducato doors were struggling to deliver bass and treble sound was awful and distorted at higher volumes. Got this baby and a couple of tweeters off Amazon. Tweeters in A-pillars and the subwoofer under the seat. WOW what a transformation. Clean bass and lots of it (if required). I can now have the equaliser flat on the head unit and get a well balanced sound. The original speakers are now more comfortable now they don't try to deliver bass and I can hear the high end too now it's up high instead of going into my legs. The sun was fairly easy to install albeit a tight fit under the Ducato Moho seat.

Some months ago I bought the 8" subwoofer. It was great so I decided to get a second for another vehicle. The listing now also included a 10" subwoofer so I bought that one instead. Sadly it is not up to the standard of the 8" one. It rattles badly at a reasonanble volume and only really plays one bass note. The build quality is also inferior to the 8" one. I can't recommend it. I'd have returned it if I'd not paid to have it installed, which involved the wires being cut, making it unreturnable.Buy the 8" one. It is built much more sturdily, does not rattle and plays a range of notes.
