...new kicker subwoofers? I hooked up everything myself. The only way I can get them to hit is to turn the gain all the way up. I heard that can damge the subs. They were already enclosed, and refurbished. Already pre-wired. Alpine amplifier is 300 rms at 4 ohm and so are my subwoofers. Even when the gain is all the way up they are not that loud. What can be wrong? Ill post links to everything in my set up right now. I installed everything myself and the only things I can think of are that my battery might not have a clean connection to the amp. the power wire is connected and the fuse is about a foot or so away from the battery? The power wire is connected to one side of the fuse and comes out the other. I really don't know what's going on. Could I take it somewhere that can tell me what the problem might be?
