Hi

I have a AQ1200d with my type R 15", and the amp goes into protection randomly, but generally when i start my truck and the volume is low, it was working nice for several months, and did that just a few times, but know the problem seen worst.

If i turn off and on the radio it start working nice, i have check my wiring but everything looks fine, what could cause this???

Sounds like it getting some sort of spike when you crank the vehicle. Could be a signal spike through the inputs or a drop in voltage on the power side from cranking. My brother's Excursion burnt the remote inputs on a couple old RF amps cause his head unit was sending a voltage spike through the remote turn on while cranking.

Is not on cranking cause my system don't work with my truck off, it happens after everything is running fine included the truck.
