amp issue

amp issue driving me nuts
just replaced my old amp with a kenwood kac-7201 2ch amp
old amp worked flawlessly but wanted something a little beter than a legacy audio.
its olny running a single 12 but the amp will only stay on for 30-40 seconds then shut off (no sound, power light goes out), the internal fan still runs and no fuses are blown. all power and ground wires are 8gauge and this is the only amp .sub is 4ohm single voice coil. i did get the amp used and think i got a junk amp now. tell me im missing something
ive gone over the wiring three times now , tried stero mode bridged, mono mode bridged, and stereo mode just left channel gain all the way down and you dont even have to play it loud at all as long as its on it will do this within 30-40 seconds

You hit the nail on the head. If the other amp worked fine, and the Kenwood is acting up, then it's a POS.

should i even waste my time oulling it apart and see if its fixable?
if not i guess its time for a Dclass amp and spend some moeny

How much did you pay fot it? What's the amp running?

It's not worth repairing.
Do you still have the Legacy amp to toss back in?

you could take it apart you self and look around. maybe something as simple as crack connection on the circuit board. but they are hard to see even for a trained eye. if you don't find anything, get a diff amp.
