Wow...I'm gonna have to try that out. I own a pioneer HU. Thanks.
HOLY CRAP! fixed all my problems!!
I think the Pioneers have an internal fuse that grounds the RCAs. They blow very easy. If you unplug the RCA while powered, etc.
The adapter I made above fixed it 100%. I have sent them to two other people and it fixed their Z1 and Z2 problems.
is there a way to check and see if the internal fuses for the rcas are blown or not? i think i have that problem with my pioneer as i get no sound, and i know everything else is working well
Mine weren't blown and I still had the whine. You can test it with a DMM if you want - take the unit apart and locate the little fuse. It is probably just easier to ground it like the pictures and see if you get sound.
Does someone have inside pictures of 5900IB? I'd like to have them so I could replace the blown fuses in my HU. Size of the fuse would be nice too.
wow i am soo angry that all this time i had this whining problem and the fix would be this easy...THANKS A MILLION FOR THE INFO...even with Zapco amps and symbilink cable (supposed to give no alternator noise) i still had whine from this simple RCA messup....i have the 6900 UB from pioneer and will share this info to anyone else who has this problem.
On my avh5900 the rcas arent on the headunit...they are connected via a plug in...what should i do?
works defintely dudes.
did it on my truck and two friends cars too.
Had a horribly loud whining noise from my amped speakers up front after installing a kinetik battery in the trunk. Asked on here about a fix for that and ended up grounding my RCAs on the HU ( I have a pioneer) and it worked like a charm. Good stuff.
Im trying this tonight on my girls car.
On a 4900 The whine is loud as hell.
Hopefully it will work.
If i'm getting engine whine through my highs and no noise through my sub then my guess is it's not the headunit but the amp's grounding instead? Anyone know?
I did it and it worked like a charm.
Thanks.
i have yet to try these methods as i am at work but i will attempt this when i get home.
just a quick layout of my problem:
I hooked up a 400watt jenson and when i turn my stereo on, it's perfectly fine. no noise or anything. when i "START" my car, the noise comes on the second my stereo kicks in. i thought it was the sub that i hooked up so i unhooked it and nothing happened. i have my remote, speakers, and rca's going through my center consol along my stick and e-brake (my car is a 97 tiburon 1.8l 5-speed) and under bout 1 ft of carpet to my trunk and i have my power cable running along my passenger door. my ground cable has an excellent connection.
can anyone give a suggestion on this?
I have opened up my DEH-P5900iB headunit, but am unable to locate even a single fuse... I cannot find any tags labeled with FU-???Quote:
