lanman31337 Posted July 4, 2009 Author Report Share Posted July 4, 2009 well if u take out the rca's it shuts off. so its grounding through the rca some how. no ground to your deck at all? does it mount to metal in the dash? Most definitely grounding through the RCAs. The chassis itself is not grounded in the dash. I have a separate wire run from the battery to the radio for a ground.

cvxsmitty58 Posted July 5, 2009 Report Share Posted July 5, 2009 It happened to me when i was doing one of my first installs.......had the pos hooked up to the amp as well as the rca's and wanted to check if i had power (using a dmm) so i grounded the dmm and touched the pos terminal.........anyway the amp light came on and i was wonderin what the hell was going on......so rcas do provide a small amount of ground i guess Quote Link to comment Share on other sites More sharing options...
RamenNoodles Posted July 5, 2009 Report Share Posted July 5, 2009 The question at hand is, why didnt you unhook the amplifiers positive power wire as well? 10 more seconds could have saved you hours of trouble.

lanman31337 Posted July 6, 2009 Author Report Share Posted July 6, 2009 How is it saving me hours of trouble? I tested the amp with muting plugs, so amp checks out fine. For some reason, it doesn't matter what head unit I use, or which RCAs, it uses the outer of the RCAs as a ground and introduces alternator whine/ignition noise with the key at ignition.
