Re: rt 202 led light red and no sound

With the system turned off, disconnect the speaker wires from the amplifier. Turn on the system. If the light stays red, then the amplifier has an internal problem. If the light turns green, then your problem is a blown speaker, or a speaker wiring issue.

Next to no output from amp. verified all connections and power, ground. Protection LED not on. green LED light is on. verified sub is in working order. this amp is need of a service. what can be done

well... you have to wire the sub correctly to the amplifier to get good sound.. you could be giving it like an 8 ohm load and this will cause the amp to put out barely anything at all.. and the subwoofer wiring diagram willl tell you all you need to know...

Have power but no sound

U may have blown the High Out put.

Not sure but is the Protection Led light on the AMP. if it has one it should be green if everything is Fine. Red or Flashing Red is not good.

U can test it has a low in out put . But if only has RCA out then u may want check the Fuses inside the AMP... Be careful because if u open it up after it was just turn on u will get a ZAP if the amp is not fully discharged.Look for any burnt Resistors etc,

Let me know if this works!!

Could be the ground. Or touching wires. if the speaker being hooked up are pulling the wrong ohmage it could also shut down an amp.

My amp is on but the protection light stay's on!!

Disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If the protect light remains on, the amp likely has blown output transistors.

hi, your amp seems to be getting power but the cables might be wrong so it's not getting enough power. the light on the amp should be green if everything is going well. are you sure the cables are suitable for your amp?

Red LED "Protection Light is on" What is the problem

The red light means the amp is in protection mode. A few things can cause protection mode..... First disconnect the subs completely from the amp, and turn it on, if it powers up you have blown subs. Also try checking the main power wire at the battery...sometimes the current your meter is seeing is backfeeding from the remote wire, so your main power line could be blown at the fuse under the hood. hope this helps

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.
