Sounds like a grounding problem. Probably one of the wires is rubbing on a sharp metal edge and may have worn its way through the shielding. If you did it yourself, retrack the wires. Otherwise bring it to who did it and they should fix it for free.
Sounds like you have a grounding problem in one of your amps. Dealer can replace the part under warranty and fix it easily.PHLOCKER said:I have this issue with the stock Bose without any aftermarket equipment addeed.
