amp keeps going into protect mode
so after about 5-10 minutes of listening at high volumes (greater than 50/62) the amp going into protect mode until i turn it down for literally 3-5 seconds and then it comes back on.....
i checked my manual for the amp and it says:
-speaker wire may be short circuited
-speaker output contacts ground
-unit malfunctions and a DC signal is sent ot the speaker output
-internal temperature gets to high
-ground wire of the center unit or amp is not connected
i checked my ground and it is good, but on my headunit wire harness there was 2 grounds, one on the aftermarket harness and one on the radio... i only have the one from the harness grounded, but everything is working.....
my speaker wires are good and brand new
the amp gets a little warm to the touch but seems ok
speaker wires are not contacting ground or vise versa
so im only left to that one ground wire, or a DC signal... whatever that is

no when i have it loud the subs do not distort or clip, and they arent blown because the amps power light turns off but this blue light stays on which means it goes into protect mode
the amp is a kenwood kac8104 mono, i have it wired at 2ohms, which it is stable at

yea thats probably what is it, the ground cant keep up with the power at high volumes so it goes into protection to stop from overheating and blowing
then after a few seconds it cools and comes back on, then i turn it back up and it does the same thing

I had a system years ago that used to do the exact same thing. I'd crank it up, bump for a few mins and it'd go into protect. Does your amp match/exceed your sub ratings? Cuz my problem was too much of an under powered amp for the subs. Put in a new amp with higher power and never had the problem again. it's always better to turn an amp half way up to power the subs than to max it out and only half power your subs
