This thread has convinced me pioneer *****... :(
NAIICE. I been having some trouble too. Just moved my grounds and to bare chassis so its not those. I may try and reground my headunit to a bolt I found out today that It is either the rcas or the headunit at this point. As there is no alternator noise until the rcas are connected into my speaker amp. And as for grounding the rcas, i haven't heard of anyone with problems with a clarion headunit, and my last headunit (Sony) Also had the same problem with the whine
i have pioneer 4900. i tried everything. moved rca on opisite side of power wire. moved amp 20 times. moved ground wire to amp to chas under car. tried bolting ground wire to frame and running to headunit.
nothing worked. the sound just drove me crazy. when your idle its at its loudest. i just couldnt take it anymore. i found this site, and i was like ill give it a try. and it works!!! omg thanks so much. i couldnt beleave pioneer havent fixed this. this will be my last pioneer...sad, i really like the radio. wish they would fix it, or do recalls and fix it for free. but thanks so much.
heres what i did, hope it helps someone see.
Wow, some big *** pics there! :eek:
yea i took them with my iphone hahah. i didnt know they were so big.
Very Informational thread.. I currently just barely installed a 4 channel amp running all 4 doors, and newly Just started having this whine problem.
Today while idle it was blaring, and hitting gas even when in park it gets louder, but turning volume up even when playing nothing doesnt increase it.
I tried turning off my HU and the whine stopped. This makes me think its either the 4 channel amps ground, the HU needs a better whine (but never noticed it before and its the same HU from when I only amped the sub) or its the RCA's bit I got nice ones. Any suggestions? I think i'll try tapping into and adding a better ground for the HU, and rechecking the amps ground
New to the forums and I too am having a buzzing sound after I installed my Alpine amp. I have moved grounds and still no change. I bought a couple ground loop isolators and it did cut the buzzing sound in half but now I lost bass in that channel. I am not running a sub so the outcome of this *****. I have a JVC KW-AVX810 head unit and the new amp is an Alpine MRP-F300 any ideas :confused:
dont unplug rcas from amps when they are playing or dont reconnect them when there playing
I let my inside (positive) pin from the rca touch the ground part of the rca input on my eq and now its whining probably blew a ground fuse somewhere
About a year ago, I bought a pioneer h/u and decided to not ground the RCAs, and until a few days ago, everything was fine. somehow, i got some power surge or something that fried my RCA cables. when it first happened, there was no sound so I figured some wire came loose. i get out and check everything and no wires were crossed and everything was still plugged in. i crank up my car again and im getting sound, but theres some incredible noise through the subs and door spkrs. i looked at the ends of the RCAs as the ones going to my sub amp are transparent and they look really ****ed up.
i wonder if this RCA grounding trick would have prevented my cables from getting fried. guess once i replace them and do the ground, ill find out. i dont think my h/u is ****ed but i wish it were so i could get a new one from the warranty and sell it. i need something that doesn't have a seizure while trying to play CDs with microscopic scratches.
got my new RCAs in today. first i plugged em in without doing the grounding trick. still the same insane noise as with the other RCAs. did the grounding trick and tried it again. ZERO noise! woohoo! maybe my other RCAs werent shot but oh well, ive got better ones in there now.
