Re: AMP GUARD ON
I'd say go back to the guy who installed and get him to do it right. He's either left some wires exposed so they are intermittently touching, or has an open connection to one of the speakers. The amp will shut down to protect itself. He may also not have wired the speakers correctly. Some systems don't work unless both hot and ground wires run directly to each speaker. Some installers run only a hot line and use the car body for ground. At higher powers this can cause amp shutdown or keep it from working at all. In any case the installation wasn't done correctly.

It would be rather difficult to diadnose the problem while in the dash with various unknown wires connected at the back.
I think your best bet is to take the Stereo out of the dash & bench test it.
Or get the service people or car radio installation guy to test it as it might be shot & need replacing anyway.
sound like you have a lose connection it could be the cables on to the dash or the socket it fits to. you would need to remove the dash and clean the connection and re fit it. if you push on the dash does it stop. ? just check this first as some times its just a tiny amount of play in the connections that's the problem .
This is caused because the stereo you have put in, is a high power output, or higher than the factory and puts that extra power into the factory amp systems causing the amp to surge the power to the speaker resulting in the pop sound,most newer cars use a stereo system without an internal amp so as to reduce heat and a external amp in usually under a seat or dash and a high power stereo boost the output of the amp.
i had some similar problems after i installed my aftermarket radio and i had to go back and rewire it and now the dash works fine. you might want to double check your wireing. i know wiring a stareo is simple but after rewiring i didnt have any more problems with dash lights
depends on whether u installed an amp for the door/dash/rear speakers or not or if it came with a factory amp for these speakers. fuse box is in 1 of 3 places, 1 under the driver side dash, 2 in the glove box, 3 on left side of dash. also if this stereo is not factory u might want to check the fuse on the stereo itself to see if mayb it has gone out or has burned the outputs.
, the message you are getting is "amp guard". This is the mesage it will
display when a short in a speaker wire or speaker with low impedence is
hooked to the internal amp and sends it into protect mode, shutting
down the amplifier section while the rest of the unit continues to work.
They either installed it under a seat (easy) or behind the dash (hard). It's probably behind the dash, which means it's gotta be all taken apart. When they were installing the head unit they prolly just stuck it right behind it. So it's basically a pain in the ***. You'd be able to find it by following the wires from behind the unit. I have the same problem, I might just take it to the guy who installed it and have him do it. Call around to different stereo installers, they may charge you like 30-60 bucks to have it done... it's probably worth it considering the pain it is getting the whole dash apart and back together again.
