Hello, I have a question. I'm a complete noob when it comes to car audio. I bought a car that was already wired and had a sub, an amp and a eq unit (I think that's what it is). The problem is, the sub was old and moved on to a better place recently. So, I bought another sub. A 1000 watt, 2ohm kicker from best buy. Now, my old sub was a 12inch 4ohm Kenwood. I'm not sure if this is the problem itself, seeing as the impedance of the Kenwood is higher than the kicker. Maybe my system is set up that way. I'm not sure. Anyway, I wired up the Kicker. I had to cut the wires because the kicker needs open wires to hook up and the wires were set up with these "boot's", if that's what they're called, to hook up to my old Kenwood. I rewired, checked to make sure they were set up properly, and hooked them up. No sound. Rewired again. No sound. And again with no sound. So I'm guessing it has something to do with the impedance of the woofer, but that's just a shot in the dark coming from me. Any help with this? I'd appreciate any feedback. Thank you in advance.

Edit: Just to clarify what I have as far as amps and stuff go, I have a American Pro Bass Machine that's 600watts. The eq unit I can't remember off the top of my head. And a Kenwood deck, if that helps any.
