pioneer pico fuse?

Do all of them have it. My hu has worked flawless since installing it with no alt whine or AC fan noise. Today I pulled it out to hook up the mic for time alignment and when I did it made a loud scratchy noise. Ever since then only when the car is on I get alt whine and AC fan noise through the speakers. When the car is off it sounds great. P980bt is the hu in question. Thanks

yes they all have it and they ****. you can send it in to get fixed or just ground 1 set of rca's to the chassis of the deck and fix it your self.

Does that sound like what happened?

Does that sound like what happened?

did you unhook the rca's while the deck had power running to it?

 

[gqjeff 10+ year member]

Yes when I pulled the deck out the rca came out. Does it make since I only have the sounds while the has the engine running?

yes that is correct the alt isnt running if the car isnt..

The ac fan also.... I am pissed off. Any idea of turn around time and cost or can you supply a link to the grounding of the Rca's to the chassis?

stinger ground loop isolator works wonders takes like 90%-95% of the noise out. i had a DEX-P1r and a PrsX-720 and the combo was loud until i did the isolator it kicked ***.

If all else fails I will go that route. Rather try and fix it instead of masking it if grounding them is easy enough. Thanks for the heads up though.. Last resort or do a lot of guys run ground loop isolators?

DIYMA has a tutorial on fixing/replacing it, otherwise ground the RCA's to the radio chassis and be done with it.

I heard it's like $90 and about 2-3 weeks. the pic above is what you need to do but you can also do it in a cleaner fashion.all i did was unscrew my rca a little pinched the wire in it and tightened it back up then hooked it to the chassis.just dont ground the center pin of the rca

oh yeah my deck had a huge problem when going from 0-1 on the volume there was a loud thump and then it wouls make like a sinewave though my woofers like I was burping my van and this fixed it for me
