My amp will trun on but it wont put out any sound when hooked up. the protect light comes on and stays on.
If your amp powers on with protection light, try the following: Unhook all input RCA cables on the amp. See if that helps with protection light. With a DMM, measure the voltage going into the amp's power connectors. If it's less than the minimum required by the amp, protection will kick in. Also, check for over voltage, too much volts can also trigger protection. Check your speaker wires for short. If some of the wire strands are loose and touching each other or the chassis, it can cause protection. Basically try the amp with no RCA inputs, no speakers attached. If the protection doesn't go out, then you have an amp problem.
It's blown....probably, check your connections and make sure your presenting it an ohm load it can handle....so check the sub with a dmm.
