Hello. Check that there is a minimum of 12 volts present across the ground and B+ terminals as the remote leed is connected. If the voltage is OK then there may be an internal fault even though the gauges light up. Be sure the RCA ground has continuity with the 12 volt ground and that the speakers function.

When power is applied, one sub hits fine and the other looks like its being pushed out really hard, continuously.


sounds like the amp is sending dc voltage to the sub. you probably have bad output transistors in the amp.

How to fix protection light


It's usually your ground. Make sure it's secured to something metal. If it's a painted metal, sand a spot down to the paint for the contact. It could also be a screwed up speaker or even interference between wires. Make sure they're separated and insulated.

Amp not putting out sound


This is not a problem that a normal comsumer should try to repair themselves. It's time to take it to a pro. It sounds like you have blown out at least one of your output channels. If you are getting any red light at all then the good news is that the power supply section of the amp is probably still good. About half of all the electronics in your amp is for the power supply section. The other half is for the actual amplifiers of the amp. Good luck, I hope it's not too bad.
