OK, I have thought about putting some subs in my TTA and decided that if I do it, they have to be removable (for the track) and sound VERY clean. I currently have a Clarion head unit and Kove audio 4x6's and 6x9's in the stock locations powered be the head unit. It sounds really good, but lacks the bass required to sound Great. I don't want to go crazy and redo anything I have, I just want to add some bass and need suggestions from the experts. Basically I want a box and amp that would match what I already have.
