Sounds Amazing
NICK MARTIN on 18/03/2020 5 star rating

I recently fitted this sub under the passenger seat of my NV200 van. I connected it to a new 9" android headunit and it works brilliantly. I had a few issues fitting the switch wire but that was down to my inexperience not the sub. I am looking to upgrade the door speakers with components with tweeters in the a pillar trims but that will be a future project. The sub sounds amazing and I highly recommend it.

Best Power Solution

Hi What would be the best solution to power this under-seat sub?

Amazing bit of kit
Mani K on 31/07/2019 5 star rating

I have a little citroen c3, this lil beauty under the drivers seat is amazing! For such a small sub its kicks out a decent amount of bass!! Not window shattering but makes the rearview mirror shake. Doesn't give off low bass but gives music a more fuller sound comfortably in the mid ranges. Perfect and just what i was looking for after changing the head unit. Installation for the sub was straight forward too... highly recommended!!! :)
