super feedback only to subs

[stanleym]

getting ultra feedback through my subs
e.g. when i change songs on headunit sounds as if the subs is picking up the change of the laser etc

i think it is the rca's anyone else give info i got pioneer deck 2 12" subs and no name brand rca's

i planning on getting some expensive new ones

the feedback doesn't occur with the hpf speakers front and back only with the subs could it be the amps just on one side only thing is i have 2 boss 1000 watt 4 chanel and it getting feedback on both

cheers for any help

Usually that happens when the speaker wires are passing next to the power cable.

Have you tried relocating the Sub's wires?

[stanleym]

done all that seperated everything with no luck

i took out the rca's for the subs and it didn't do it again and then i placed my other speakers rca infront the same port as the original sub rca and was still fine

i thik it is the rca's or at worst headunit as i relayed the remote etc

with my brothers old car (camry 89) he was running a kenwood head unit and 2 JBL 6 x 9's it had the same problem, but he had to change his RCA cables..
and it worked for him.. might work for you just grab a pair of cheapy 1s to see if it is the RCA cables

Make sure that you have the power wire running down one side and the RCA's down the other side and make sure they dont over lap in anyway and with the speaker wires i run mine down the same side as all my power wires and i dont have any trouble with mine, alsoyou can also try to get your hand on a ground loop isalator for the RCA's as well.
The other thing is have you checked all your grounds for paint and for a good conection as that can also transfer some noise.

MAke sure the AMP is not attached to the metal chassis of the car otherwise you will get nasty ground loops/feedback.

So if the amp(s) screw holes are metal, get a wooden board and screw that into the chassis, then screw the amp on the wood.

And yeah try relocating the RCA's.
