Got 2 6 inch JVC subwoofers I'm putting in my saturn in the back window. Got them mounted and everything, and I was wiring them directly to the speakers in the back window..and everyone told me theyre so little i wont need an amp. So, I wire one to the back window speakers and BAM, no speaker in the entire car works. As soon as I unhook them, they all work. What do I do? Is there a way to run to the battery, or to my CD player??? HELP PLEASE!
