System Problems

Well I got into my car today, and the stereo was about mid volume. The cd played for about 10 seconds, and then it was like my sound was cut in half. So I shut off the car hopping this would reset. When I turned it back on same thing. I am running a JL 300/4 bridged 150/2 to Rainbow Germs. I have been using this setup for about 9 months and its been perfect until now. The deck is a kenwood889, and sub is 10w7 with the 500/1 amp.

When I turn the sound up the Sub sounds just fine. There are no Protect lights going off on either Amp. I checked the battery for ground problems and every thing seems to fastened down properly. I have had the stereo cut out but only at very high volume. and as soon as i turn the deck down, it fixes the problem.

Any Ideas on how to fix this would help greatly. Thank you in advance

Voltage more than likely, a heat issue will lessen the sound on JL amps and make the sound distorted, so I think it is a voltage issue when it goes into protect keep it up and look at the amps.
