i know its a really common s10 and blazer thing i get feedback threw the subs like the motor and turnsignal noise, when it used to do it i could click the door lock back and forth and it would stop. but now its a constant annoyance. the amp is grounded very well please help!

 

you need to check the ground on the radio its self. I would also do the big 3 under the hood.

 

Yup, ground on the radio is big. And if that doesn't help, sorry to say, turn down your gain.

 

What is the amp grounded to? Tell us more about your system.

 

I had the same problem with my system. Even after the big 3. I used a set of RCA Noise Isolator's on the amps and it stopped the feedback coming thru.

 

I had the same problem. i fixed it by grounding the RCA cables to the radio itself. i took the red RCA, cut the plastic casing, trimmed the plastic around that and ran 18 gauge wire from that and twisted it around one of the radio's chassis screws and tightened it back down. worked great until i upgraded the RCA cables to higher end JL audio cables.

sorry if i confused you with that. i can reexplain it if need be
