Hey, I have this same amp and had almost the same problem. Had it connected properly and was constantly getting the red protect light. Sometimes when it was switched on it would turn green then immediately go to red. I checked everything and tried everything I could think of. I am a corporate jet mechanic and know my way around electricity very well, and I was sure we had this thing connected correctly. Then out of desperation I tried running a wire from the battery neg term to the amp ground terminal, and presto it worked. Turned out the ground I was using was not good, even though I could see it was connected to the chassis, it still wasn't getting a good ground. Reconnected it to a different ground and it is working great now. It needs a really good ground.

Hope this helps someone...RC

Sisnce you didn't mention the protection LED, I'll assume it's not on.

You need to measure the voltage across the B+ and ground terminals of the amplifier to confirm that the voltage at the terminals is least 11 volts. Also check the voltage on the remote turn-on terminal. Place the black meter lead on the ground terminal of the amp and set the meter to DC volts.

Im trying to hook up my subs to this headunit but i cant get the power from it to the amp. The amp is good and the subs are good

have you got a wiring kit for the amp? the amp needs atleast an 8 guage tho id suggest a 4 guage running from the batter to the amp with a 50 to 80 amp fuse atleast, then it needs to be ground to the chassis. a remote wire then needs to be run from the back of the headunit so that the amp only turns on when the ignition is on, then hook the wires from the amp to the sub.

No sound but green light is on

First of all Id like to state that Reality car amps arent the best quality amps on the market and they normally will burn out on you. From what you are telling me it looks like your sub outs are defective, the output signal from the car amplifier is dead usually due to weak or defective terminals or poor soldering by the manufacturer, very common with lower quality amps. My suggestion is to replace the amp with at least a mid grade amp like a sony xplod or pioneer amp , if money is an issue then you can have the outputs checked out , check the wiring and also make sure that your ground is solid and making good contact to the cars chassis otherwise you wont get sound. Check the Amp turn on cable which is the small blue wire and check that your radio has the amp turn on or subwoofer signal turned on. Let me know your status and Ill do my best to help you out.

Good luck,

Subs wont work or do anything when hooked up

Check your safe light on your amp if it's green then the subs are **** but if you don't have a green light check your ground, just because it sparks when it touches dosen't mean it's a good ground so grind the paint off the bolt if need be. If all else fails get new subs, do your self a favor don't get lanzar products there horrible trust me on that one

I have a pioneer gm-d8400m the amp isnt working

flashing light could mean a few different things. 1- constant power may not be there. check with a test light or multimeter. should read around 12 volts. it would be a good idea to check all the power and ground leads. make sure u have a good ground. 2- bad sub. im assuming sub since its a monoblock amp. you can meter the subs. make sure the total ohm load is no less than 2 ohms. any lower the amp will go into protect mode. 3- bad amp. power supply may be bad. the newer pioneer amps are full of protection circuits. ive been a professional installer for a shop about 8 years and we sell pioneer. hope it helps.

Power good no green light no subs

Make sure you got a good ground. do not ground on painted surfaces! If you got power from battery, check the remote wire running to cd player. Hook up remote blue wire with the one for cd player. If you still have a problem and the fuse is good, then the amp is fried

Kicker 750.1 Amp wont play music

it is probably the rca inputs on the amp may have fried. was your cd decked turned up loudly before the power went out? did any wires accidently touch each other? If had worked fine and then suddenly stopped, than either a wire came loose or the inputs fried. try using different cables and I also suggest disconnecting power for 24 hours and then reconnect. If the green light is on then it is getting power and the problem is in the rca cables or the inputs

Jensen Amp and Sub

If you followed the instructions correctly, then the amp must be defective. This is sort of simple.

My generic suggestions:
You have the power, the ground, the outputs to the speakers, and then the input.

Make sure that none of the speaker wires are somehow being grounded. Make sure that nothing is shorted that feeds the speakers.
