Hey, my first post on the board! I like it so far and I expect to be posting a lot more on this forum. I'm very new to car audio, I just got my first set up about 2 months ago. I hahve 2 12 Ultra Linear Subs and 1 1000 XA Eclipse amp, yeah nothing great ( All for sale) My new set up I wanna go with a 15 BTL. I was wondering If I could get some advice from some of you with what I will need to get this sub to reach full potential Amp,Battery? Capacitator? etc.. Thanks guys, and great forum!
