This usually means that the speaker outputs are being shorted out or ground is not secure. My suggestion is to turn it off and recheck your ground and speaker wires to check the are secure.

Amp light not working and one dead right channel


Without knowing how it's actually laid out, I'd surmise the output amplifier transistors in the right channel are shorted, the fuse for that channel may be blown, and the speaker protection circuit is keeping it turned off. Most amplifier speaker protectors disable both channels if there is a problem, but yours could be different. I surmise the lights you mention are directly connected to the speaker protector chips and indicate readiness for normal operation. If it takes a few seconds for them to come on after power-up, that lends credence to my hypothesis.
Unplug the amplifier, open it up, and measure the resistance from the right channel output to each of the output power supplies (or to the fuse for the output power supply for that channel, if present). If one or both is very low (i. e, close to zero), you have a fried transistor. If that is the case, it is probably a good idea to replace the complementary transistor connecting the speaker to the other power supply even if it tests good; it may have been overloaded when the first one shorted. In many amplifiers, the transistors are inside a hybrid amplifier module, so you would have to replace the entire module. In some amps, you have multiple transistors in parallel; here you can probably keep the transistors that were in parallel with the failed unit, but I'd still recommend changing the complementary transistors.

Amp repair


Check all your connections to make sure wiring is correct, if the light stays red you have an internal fault in the amp.

Sounds like the power supply is shutting down because of it sensing a bad output channel. I'm assuming of course that you have checked all your battery, ground, and trigger wires to see if they are OK. Good luck.

switch off the amp then take off all the wires off including the speaker wire and then reconnect the wires on like before the problem is that the amp is on protection and if that dont work then get it repaired another thing is make sure ur amp fuses havent blown.
