[QUOTE="JohnKuthe, post: 8525767, member: 670903"] Well, I lied. I didn't get out to check any voltages, but at least both amps are dead cold after my vehicle has been sitting all night in my garage. So the amp heating problem is definitely only occurring when the ignition is on and happened yesterday after the ignition was on for a while with me driving out there then sitting in his driveway working on the sound system with the key in ACC position to play the new Alpine HU and Alpine speakers though the stock speaker wires. Will test again next Wed when I go out again to do some more work on getting this audio system installed. Something is terribly wrong, possibly the big bolt we found around the periphery of the Stow-n-Go seat compartment along the rear edge is NOT a good ground! Sure seemed like a good strong structural thing, so we loosened and spun the nut off, my installer guy wire brushed it good around the stud and surrounding area to make as good electrical connection and installed a big ring terminal and replaced and tightened the nut assuming this would be a good ground and installed a ground distribution block on it with a fat 0AWG cable. Gonna have to check that first. These newer cars are rough to find a good ground with all the PLASTIC they use in vehicle construction! :-( John Kuthe... [/QUOTE]
