I have a Sony 500W amp hooked up to 2 10'' Subs. When I put power to the amp it lights up green like it is supposed to, but when I turn my music up a little bit, the amp turns off into protection mode and the red light comes on. What should I do?

Re: Protection Light Comes on
Sounds like you have an ohm problem, Tryy hooking the positive from one speaker to the negative on the other speaker. Then hook the negative from the first speaker to the negative on your amp and the positive from the second to the positive on the amp this will drop your ohm load and the amp should stop going into protection.

this is caused by inproper wiring from the speakers/subs to the amplifier.. an amp will still put out power to subs and speakers when it's wired improperly but it won't last for very long doing it... 6 months is longer than usual....
i wish i can chat to you live so i can ask you qestions about your amp but to figure out what section of the amp might be fried it could be the power supply section could be the out put section or the in put section but i would try process of elimulation try unplugging your rca jacks and your subs unhook to your amp just the power hook up and try powering it but if the protection light steel comes on then try to remeber the last time your amp was working good and playing your subs was your amp getting hot if so you probaly fried your out put chips and not telling what else next question was you just hooking your amp up in your car and acually touch one of the power wire to the ground on your amp this happen to my friend and fried the power circuit relay chip on the power supply thats all the advice i can give but usually when the protection light comes on and you got every thing hook up right something fried
You will need to show it to a service technician as it seems the output section has blown so it remains in protect mode. One reason (could be) that the input to the amp was high and may have been clipping for some time before the amp decided it could take it no more
You cannot parallel two subs AND run them on the Bridge. You must have at LEAST a 4 ohm load on the bridge, and 2 4 ohm subs in parallel equals TWO OHMS. BAD!!! Move each sub to it's own channel or your amp will soon fry.
