I have a 97 yukon with 600watt amp and punch subwoofer and 2.0 capacitor. Recently when i have been driving my speakers in the car would cut off but the sub would still stay on and play the music. Now when i turn on the car, the speakers go right out if i turn the volume up past a certain point or rev the engine, its really wierd. also the speakers work if the car is off and running on the battery some times. I have no clue whats happening. Maybe i need a new battery or a new alternator?

It sounds like there is an abnormal strain on the radio.
Please fill in a few blanks for us.
What type of radio is it?
How is the sub connected?
Are the front speakers on a seperate amplifier?
How long has it been doing this, how long before it started?

i have a pioneer DEH-P480MP, the subs are connected to the amp directly, the front speakers are stock with no amp. just a mono amp in back. it has been doing this for a long time prob. about 2 months, it has been getting progressively worse (i.e it started out that i couldnt turn the volume above like 35 and no i cant turn the volume above 10 without it cutting the speakers off.) It didnt do it when i had my old kenwood cd player so idk what it is...

is there any popping or crackeling in any of the speakers?
First turn off the sub, then try adjusting fade / balance to isolate each speaker. Fade it all the way to the front left, and turn it up to 30, then front right all the way to 30.
It sounds to me like there is a speaker shorting out. By testing each speaker individually with the fade / balance, you should be able to find the problem.

I would tend to go with 2 main checks.
1. Check all speaker wires and connections at the HU/aftermarket harness and make sure you have tight wiring connections to each speaker line out. Crimp connectors or soldering with shrink tubing are best. (Not twisted wires and tape)
2. Check your HU grounding line. It's better to use a hardwired ground to the metal brackets in the HU pocket rather than the harness ground.
Also, consider disconnecting the sub RCA's from the HU and see how well your F/R speakers play w/o the sub. These steps should help isolate the problems noted.
