UQ7 gain switch & amp
hello guys,
I think somehow my factory amp got fried while welding in my sub frame connectors. My battery was disconnected before the weld in, but I lost my amp right after that.
The light turns on for the gain control but I dont hear the amp power on, nor do I hear my subs kick in or get a response when I slide the gain control ****..right or left
any inputs?
sincerely,
Lennie

The amp is easy to get to, it's located just behind the plastic panel under the map pocket. On the amp, check for:
12v on the pink wire at pin #13.
Ground on the black wire at pin #14.

It maybe the gain switch itself,they do go bad.I replaced mine awhile ago and that fixed the problem.
