Aren't you an electrical engineer by degree? You should know what to expect.
The heat being generated was NOT at all what I expected.
Are your grounds sufficient and how were the gains set? It's odd that it would be both amps if it was a warranty issue, so if it's both I would say it's an install issue. What's your voltage at the amp?
Dunno, gonna find out after my dinner, if I can easily. I have a VOM and know how to use it. Will report here. And the lower power PDR-V75 is not as warm, but still warm.
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! :-(
Yep, apparently! Gonna have to rethink that ground. I was actually planning on running TWO big power cables right off the battery, a 12V+ and a battery ground. Don't get any better ground than that! My installer guy and I both thought it was very fortuitous to find that big 19MM bolt in the Stow-n-Go storage compartment. But apparently maybe it is a bad grounding point. Gonna have to test it!
Why do you comment more about people than you do about car audio? Jealous you don't have a fancy formal education like I do??
I'm ejemecated enough to test a ground and I'm not a EE.
Yeah, I used to work for the Military Industrial Complex, facilitating designing and building bigger better ways of killing more people faster. Money was good but I got out of that nasty evil line of work and became an RN so now I am HELPING people via direct patient care and my karma feels MUCH BETTER!
None so blind as those who cannot see.
