I had to re-post as no one helped me the 1st time.
Winter beater special!
Well my amp keeps going into protect mode I turn my car on amp goes green, speakers crackle and it goes into protect mode.
I was just driving and it went "crackle" and speakers stopped working} so I took the speakers off (no load on amp) and it went into protect. Took out the RCA's...and it went into protect. I swapped the amp out with another, and that amp didn't seem to want to work either.
Ground is where it has always been, bolted to the floor (sanded down metal).
I have NO idea what is causing this as the 2nd amp wouldn't even power on......could my cd player be garbage?
Use DMM and measure the voltage going into the amp. Check the ground too. When an amp goes into protection that often, it's either getting overloaded from HU, bad amp or lack of voltage.
