Getting feedback noises from speakers and sub...help?

[BFF Larry]

I don't think it would hurt to try. Maybe even any ground other than the one from the harness? That's how my deck is grounded. From the back of the radio to a piece of metal behind the dash. Hope this helps!

thank you for replying!

and ill try to ground it to a metal bar under neath the HU

[BFF Larry]

It just started out of nowhere. Ever since I stupidly plugged the rcas when car was running/amp.

Pioneer hu will blow an internally fuse unlike other brands who use slow- blow ones

Today after work. I grounded my RCAs at the hu, grounded hu to inside dash bar, AMD also grounded it to one of the dual inputs for my amp.

But I still get alternator whine, white noise when nothing is playing, and pops and clicks when I brake or Rom my volume knob on hu up.

I don't understand what could be the problem...

I checked the grounds in my car and all but one to the chassis in the trunk was loose.( cheap wire broke terminal ring.)

I fixed that and still yet feedback.

I unplugged the rcas from my sub amp and still white noise coming from the subs when gain knob is maxed when no music is playing.

And even when the rcas or unhooked from the sub amp, I get clicking noise when rolling the hu volume anywhere from 5-20 when gain is maxed....

I've done everything I could think of besides checking the RCA jumper to the Pac-lc 1.

What could he causing all this feedback...

You cannot hear any of this noise when music is playing but once its quiet, you hear it.

Using my turn signal, flipping the headlight switch, and the press of the brake all cause pops and clicks through the highs and mids...

anyone has any idea what's going on.....

unplug your rcas from everything so no signal is being sent to your speakers if you turn on your lights and still get the pop noise or any other noise it is a ground issue so there is no signal being sent.

Okay ill try Tomoro morning.

Thank you vans.

If its a ground issue, where should I check specifically

lol, I stopped by my local custom audio store for the first time since I ditched them for CF and SE as a source of gear.. they had those power wire adapters that delay signals for popping etc. marked down to 5 dollars I'll put it in tomorrow since I have one job only now and have time to see if that totally solved my issue I still think the RCAs are unrelated to popping, but it's worth trying. I really do wish you luck lol.. hang in there.. I'd be stressed if I had all this going on.. could always get a new headunit. wouldn't see me with a pioneer, dead or alive.

Ah dang, that's a Steal Ian!

Post pics of it and how do u wire it

[Ian01]

used webcam because I'd never remember to get the camera out..

red wire: constant 12v source (battery/amp power wire)

black wire: ground

blue wire: new remote wire

gray wire: any wire that reads at least 5v when the headunit is on (I'll try running my rem wire to this first)

edit: the theory here is to deal with voltage rushes. I may try to scan the little ass peice of paper that was included with it lol.

Does the red wire need to be inline with the amp and batt?

Or just off any source not inline but separate?

I had weird sounds when I had grounds in several different places, moved them all to one spot, and it cut noise in the system down by about 50%. Not sure if it's the same problem, it was like an alternator whine with some popping.
