I don't like Xplod's or MTX, my buddy when through five in 5 moths. Really can't blame it on the subs, the box was too small, but still, I don't like the bass. JL is the best, no substitute. Right now I have no name subs, but man do they hit hard and clean. I am planning to put JL 12's in my truck with a Fosgate amp. I want a 2000 watt system, but that is going to cost some green. Don't go to Best Buy they suck. Go to a Sound shop, they won't bull shit you too much, and they actually know what they are talking about. If you happen to live in So. California, there is a shop called L.A. Stereo, in Upland. Go there, and ask for Mondo. Tell him Frank and Kara in the Black SI sent you, good deal.
