Just to add bass, get a line output converter, amp and sub/box.

No dsp needed. DSP is great if you are doing a full system.

Do not get a cheap converter the Audio Control stuff is great.

I would not trust just velcro strips for holding a box in place, especially if you do any track time. Easy enough to make a couple small straps to attach to the top of the enclosure and either secure them to the rear deck lid or place them so that they will catch something if the enclosure should happen to tip back under hard acceleration.

I do have a Audio Control LC7i that I am no longer using as I went the full DSP route. I would let it go for cheaper than you could likely buy the LC2i for. Like new with box and everything including a new knob. Hit me up if interested.
