Well, besides that, there's quite a few options, all depending on what you want to do. Lowering it, wheels/tires, audio, etc.
Besides the obvious, you'll probably need a line level converter. I've been running nothing but Image Dynamics subs for the past 10 years. These are probably one of the most cleanest, musical subs I've ever had (and I've had quite the few in my day from Rockford, MTX, Phoenix Gold (when they were still US made and good), Alpine (Type R and Type X), JL audio (10W0, 12W3, 10W3), and some no namers purchased just to blow them up for fun).
Ah. Cool. I've found them a little boomy and SPL driven for my tastes, but no doubt they make great subs (look at the Jackhammer; crazy shit right there!). I don't exactly remember how power hungry their subs are. I kinda fell out of that when I started building SQ systems for my cars.Some reason I like the mtx's I had 2 12s before thanks for your help
