This amp powers up and plays perfectly on the bench..
Once installed in a vehicle it does some crazy things..
First thing it does is cut on and off it also gets really hot fast and it has feekback thru the sube almost like theres a rca shield ground issue..
I removed the board from the sink and first thing i noticed is the amp has been repaired before..
The amp uses IRF640N's and IRF9640's as the outputs..
1 side of the outputs are the orginals IRF640N's and IRF9640's
the other side has been replaced with IRF640's (no N suffix) and IRF9640's
Since some of the 640's have the N suffix and some dont would that cause a problem that im having with this amp?
Also i found some 1 watt resistors that are 4.7K But are measuring 3.88K
So think about replacing them..
Wondering if the outputs could cause this or wondering where i should start checking ?
