Pioneer under seat subwoofer
Wiebe van Der werk on 22/06/2016 5 star rating

Just had this fitted in my mx5. The only one slim enough to fit limited space. They told me it would make a difference in terms of sound i. I expected an improvement but boy does it sound good with roof up or down. Deep base and free message for person now in passenger seat. Great bit of kit. Service very good with unit fitted same day.

great for such a small unit

needed something really small to go underseat in a gt86. this was snug, but fit nicely and gives very decent, if not quite mind blowing sound

Excellent for cars with weedy factory speakers
David on 12/03/2016 5 star rating

Just fitted two of these. One into a 1997 Honda Accord and one into a 2004 Mercedes Vito. For the money, you simply cannot knock these. They have utterly transformed both vehicles. Got enough clout to bring stuff like Sub Focus/Moby/Prodigy to life and also helps add depth to rock tracks. You'll have to sit playing with head unit's equaliser/sub settings and all also play with gain and frequency on supplied control remote but it is very rewarding. Won't rattle your number plate like a proper ported 10 or 12 sub does.....but that's not a bad thing. Wiring is a piece of cake. The only extra thing you need is a length of phono leads from head unit to sub pick up point. That aside, it's totally plug and play. Very impressive. Try Porcelain by Moby if you are in ANY doubt as to what this can do. Anyone not impressed clearly has way higher standards than me and I'm pretty choosy.
