I have a Kicker S15L7. It is a 1000 W RWS and a 2000 W Peak. Just to see if it worked I hooked it up to my car. I have a 250 W amp. I plan to get a bigger one but I don't have the money yet. When I hooked it up the sub would make this rattling noise and it wouldn't bump very loud. I didn't expect it to but it didn't like at all. I was just wondering, would it be my amp not being high enough to push it or would it be a problem with the sub?
