possibly your remote wire, i had that happen to me, and i had my remote wire ran under my dash and down the left side of my car, and when i ran it under my dash i ran it under a panel and tightened the panel down to tight, and it broke the wire insulation and the wire shorted out, and kept blowing my HU hu and radio fuses. so i fixed it and everything is all fine. just check it, i never thought thats what it would have been.
