Brought this sub for my little car to improve the sound, and decided to fit it under the front passenger seat.After a few problems with delivery it was delivered. I payed extra for wiring kit, which without i would have had no chance of fitting! In the process I had a few ups and downs, blew a few fuses. Getting the front seat and out was a struggle so think twice before you start taking your car apart. I drilled holes in the floor and used screws to secure the sub. Bit of a bodge job as not the clearest instructions. Eventually installed sub, wired up to the radio and it sounds AMAZING, the whole car vibrates. It has improved the sound in my car more than i expected, would definetly recommend as it sound almost as good as my friends more expensive more powerful set up! and for £90 you cant go wrong!
