Question about Pyle PLA2180 Car Audio Amplifier
The only thing to try would be to remove the sub wires form the amp and see if it still goes into protect. If it still goes into protect with the subs unhooked then the amp will require repair.. If it doesent go into protect then check to see if you have a shorted subwoofer. also make very sure that you have a good clean bare metal tight ground connection to the body of your car. People forget that step all the time.. Did you do your setup with the correct ohm load? Most of these amps will fail if the subs are hooked up incorrectly(too low of a ohm load). If the amp has a lowest possible ohm load rating of 4 ohms... but you have a pair of 4 ohm subs.. you hook them up togther at the amp.. both positives togther- two negatives togther.. because it "bumps harder" that way.. Then you now have a 2 ohm load on the amp... The lower the ohm load you put on a amplifier the more it will output. The problem when people do this is that the amp outputs more current then its internal parts are rated for and the output transistors (usually) fail.. most amps will not fail if installed correctly.
