when i switch tracks on my head unit the speakers woofer go in then out, making a staticy noise, this also happens when volume is turned to zero(move in then out then constant static). Thought maybe speaker wires were reversed, nope same result, tried different speakers, same thing.

whats making my speakers do this? is it cause harm to speakers?

 

see if your red wire and the yellow are in the right place

 

on the back of the head unit? or speaker?

 

rca's grounded?

 

what rcas? my speakers are hooked to speaker wire to the head unit. this is a car i just bought that was pre-wired. and i know nothing about the wiring other than that, but what should i check?

 

who wired it up ?
the 2 wires i'm thinking of is the power wire to the deck form the car and the other is the switched 12v+ form the car

 

the person i bought it from did everything himself

here are some pics of the back of the unit when i pulled it out.
there was nothing in the bottom left hookup beside the rcas

 

pull the deck out
you can see the red and yellow wire next to the green wires they will go to the car (i will say it is not right )at the point of car to deck
what car is it ?
what deck ?
what yr of car and deck ?

 

well then i dont know, check your ground.maybe ground the rca's anyway.

 

the deck is Panasonic CQ-C3301U
