Alright I just got a new head unit (Alpine 7894) and I have one amp for my speakers and one amp for my subwoofer. I also have a kenwood graphic eq hooked up. Now for some reason I get alternator whine really bad from my subwoofer. I mean the volume is all the way down and I am just idling and its just throwing out a constant like 80 hz bass signal. But there is NO alternator whine from the other speakers. I hooked it all up exactly the way that it was before with my other deck and I had no problem with this then. I can't figure it out and its hot and I'm sweating like a mofo and I'm about to throw it against the wall. Please help. Hey its my first post too by the way!
