Good Sound leads too short
ESTHER on 04/01/2022 4 star rating

The main lead to the radio is too short, about 16" or so. If placed under the seat will not be anywhere near able to reach the radio to connect which is frustrating as have to hunt a lead down. This was not made clear beforehand, so the car is in bits and then have to drive to get a lead!

Just What I Needed!
Owen on 06/09/2021 5 star rating

Installed in my 2015 Kia Picanto 2, perfectly makes up for the bass that was noticeably lacking from the sound system. Along with a speaker upgrade, I am now completely happy with the sound quality! Not going to be rumbling your neighbour's windows, but definitely gives noticeable kick and difference where bass was lacking before.

GIRTS on 27/05/2021 5 star rating

Considering the size sub sounds good, decent low ends. easily fits under the seat. May get another one to make sure i have enough power.
