i just picked up a panasonic radio the other day. don't remember the model number off hand i'll post it later. any ways it has aux in. front, rear and sub outs. when i use the sub outs it makes a bump noise when the amp turns on, or when it shuts off and when i change tracks. if i use the rear outputs everything works fine with no noises. so would this be bad sub outs on the radio? i switches rca's redid my ground on my radio. anything i could think off. need some opinions

Did you change the ground on the amp also?

My first thought is the ground on the h/u, but you say you checked that...

You should look at the amp ground and possibly swap amps and see if it still does it...

You may also try grounding the case of the h/u, I've fixed similar problems that way before...

ok with the headunit do i just wrap a wire around the cage?

 

[junbug27]

Just use an O-ring connector or self tapping screw through the back of the case.

ok i switched amps and i pulled the radio out to do the case ground. I noticed if i tap the top of the radio by the rca's the groudn noise goes nuts and it wouldn't stop till i tapped it a few more times. so my guess is i have something broke or loose inside the radio.

 

[junbug27]

Are the RCA inputs loose?

what do you mean? on the head unit? no there on wires, so there not fixed to the headunit

Most likely not if you aren't familiar with working on small electronics...

It's a broken solder joint that will have to be found with the unit powered up...

That's not something I suggest anyone do...

Well, if the noise ONLY comes through the sub outs and they are the wired kind, it's "more possible" to narrow down the problem inside the h/u...

I think you will find that you wont see much in that area by taking the top off the h/u...

Using the rears will be fine, as long as you have a crossover, or have a low pass crossover in the amp...

ya my amp has all that. i'm runnin a hifonics 1500d, well 2 after i hook up the other one
