Does the highpitch volume change if you change the volume from the source?

Shit I have squel too. Ive had it for months. It still occurs now and I have no amps connected or nothing. Just my indash.

the squeal stays the same low vol or high. i dont mind it, but will it harm my subs? thats my only worry.

Is it just your subs, or all speakers?

Does it do that when your car is running, and turned off, or just one or the other?

Could be your RCA's, not enough shielding.

Could also be a lose power wire. That is often over-looked, people think just a lose ground would be the problem, when in fact it could be a lose (+) connection somwhere. Check all connections, battery connections, ect.

Your PSP (Is it protable, I dont know on the new consoles.) If not, and you are using a power inverter, they sometimes can cause noise in a system.

That gives you a place to start.

it makes it even when my psp is not connected. both my subs and speakers make the noise. i dont mind it, but will it hurt my subs? it makes it when the car is turned on/off. I dont think its my rca's cause i use one directly to my psp in the trunk(no were near the power). where would u recomend a ground point. i have mine on my seat belt bolt. and its sanded.

thnks

uh, a new ground is in order. I'd go straight to the frame, or if you have enoughwire. straight from the battery.

do you know if that soun will damage my subs?

I dont think it will damage it, because its low enough power were ever it is comming from that it should be fine.

but please know that you should try to get it fixed.

Definetley get new ground point.

Do you have 2 amps, 1 for subs, and 1 for regular speakers?

And RCA's can pick up noise about anywhere.
