Ground loop help! Im going crazy. Please

Recommended Posts

Hey guys, hows it going? Im new to this forum and just wanna introduce myself and a problem im having.


I have a 2003 Mitsubishi Eclipse GTS and I am having that dreaded ground loop (or some issue, im not sure)


Whenever I turn the ignition to accessory, the speakers come on and sub comes on but no "whining noise" and then when I turn the car engine on and the alternator starts spinning, then my speakers emit that "whining noise."


I read the articles on this forum about fixing ground loops and I tried to do whatever my knowledge about car audio systems, electrical, wiring, etc would allow me to do.


I wrapped a speaker wire around the rca terminals on my Pioneer AVH-P4200DVD DVD Multimedia Receiver. I wrapped a speaker wire around both the front speaker terminals and rear speaker terminals as well as the subwoofer terminals and connected those 3 wires to 3 different points on the HUD itself. I also did the same thing to my Infinity Kappa Five amp in the rear. Wrapped the front, rear, and subwoofer terminals with speaker wire and connected them to the chassis of my car in the hatch.


I found some insight as to the problem, whenever I disconnect my subwoofer cables from either the HUD or Amp in the back, the whining noise seems to go away, but when I reconnect them, the whining noise comes back more so in my rear speakers than front or so I believe. Either way I just want to get rid of that **** noise.


I use Rocketfish insulated RCA cables for the speakers and I use a Kicker 2 channel RCA audio cables.


Like I said, whenever I remove those subwoofer cables, the whining goes away.


Can anyone give me any info on why the subwoofer cables or terminals are causing that problem and what I can do to fix it?


Please help me out if you can!


Thanks again and thanks for taking the time to help me.

      My list of gear as follows
      1x Boss mono block amp 2500w (old setup)
                  -twin pioneer champs Dvc 1200w 12"
      1x pioneer 4ch amp 1000w (60rms x4ch)
                   - 2x pioneer 6.5 260w (60w                                                 rms)component
                   - 2x pioneer 260w 6" (60w rms) coaxial
      Head deck : pioneer fxh755 bt (2 RCA out)
      Just wanted to know the best way to get the audio to the amps,
      1 RCA per amp?
      I've never delt with  4ch is just having 1 RCA going to give me full control or full quality on my 4ch. If I got 2 RCA splitters would that achieve anything useful?   
      Is high level worth using do I lose any quality compared to RCA? So out RCA into mono amp amd high level into 4ch amp?
      What's the best way about doing this. Is there any recommendations? I'm not wanting to spend too much money on this 🤣

      Good evening,
      I'd like to upgrade my stereo in a 2011 Toyota Land cruiser Prado 150.
      I have a factory audio system with the amplifier under the passenger seat.
      The only requirements are 2xUSB, Apple carplay and the ability to connect a reversing camera.
      The Pioneer SPH-Da120 looks as though it would be suitable.
      Could anyone tell me if this will connect easily to the factory speakers on my Prado. I would like all the speakers to work and be connected correctly, but I'm not at all familiar with these things.
      So if anyone has done this on their Prado or has any advice it would be greatly appreciated.

      Hello, I recently bought a Pioneer AVH-W4400NEX from BestBuy and using it from a month in my 2014 Ford Mustang.
      The radio was decent, but I am having problems with:
      1. Android Auto - When I connected by phone (BB Keyone), I always get a message: "To use Android Auto please stop the car and check your phone". I reset my phone completely and tried but no use. Do any one know what will be the problem for this? I am using OEM USB cable.
      2. I have disconnected the Head Unit GPS cable to have the video play in motion. But, when I connect my iPhone for Navigation, it looks the CarPlay is taking the GPS signal from HeadUnit rather from the iPhone. Is it true that Android Auto and CarPlay uses HeadUnit GPS for navigation? If so, is they anyway to change it?
      3. I see a weird message on the HU screen: "No paired phones connected" after couple minutes of start up, even though there is a phone connected via Bluetooth and music is already playing. 
      4. I noticed, randomly, when I tried to increase the volume from my steering wheel control some times it is moving to next music track. But this is random.
      5. The BestBuy technician who fixed this radio in my car told, the radio may give blue screen errors if tried to connect with AUX cable. Due to this, he didn't provisioned the AUX port. Is this true?
      Any help with above is appreciated.

      So I recently purchased 4 Polk Audio DB652's for my 2012 Subaru Impreza (with a stock in-dash stereo). I like them but I wanted more out of them so I purchased a Pioneer D9605 5 channel amp. I chose this amp because I wanted to see more output from my current 4 door speakers and a sub woofer that I am planning on getting (Rockford Fosgate P3D4 12"). I feel like I got my amp without being well informed on other factors and was wondering what some great car enthusiast think of my purchases and car audio goals. Ask any questions that I would need to further clarify to help y'all help me!  Also, are the Polk door speakers I got that great?
      All help and recommendations are very much appreciated!!!
      P.s. I don't have a large knowledge of car audio if it isn't yet obvious.

      Hi guys! I just installed audio system in my vehicle and I have problem with my radio. I can't figure out how to store radio stations which I like. I found how to program 6 best stations based on the signal strength, but this is not what I am looking for.
      On OEM radio you could just tune it and then press and hold the button of desired bank. Well, this head unit doesn't have these buttons.
      Please help!
