    grounding rca and sound quality

    I heard from my local dealer that I should not ground the RCA to head unit because I will lose sound quality. Is this true??

    I have the 880PRS
    One more thing, is it possible to get rid of the beeping noise every time i'm scrolling through the menu, its really annoying

    You don't ground RCA cables. They are just cables that connect your headunit to amps/eq etc. You ground amps, headunits, eq's, and other hardware. Yes make sure your headunit is well grounded. The only way you'd screw up your SQ from grounding your headunit is if you induced a ground loop.

    lol @ you.

    But seriously, grounding your RCA's will only HELP your 800PRS. You will not lose sound quality at all.

    Go back to your dealer and tell him hes an idiot

    edit: However do not mess with it if you DONT have the ground loop issue

    Re: grounding rca and sound quality

    According to JIM....lol ...

    jmanpc actually put up a post in the electrical and wiring forum that shows how he grounded his Pioneer head unit... http://www.caraudio.com/forum/showthread.php?t=191860 post # 9-- (dunno where the rest of it went) guess their is some design flaw in most pioneer head units causing them to be noisy... he had a picture on there showing how he resolved his problem... The "ground" is basically a sheild for the inner conductor and a well grounded system, front to back, will be quieter, or possibly even noise free.

    Re: grounding rca and sound quality

    well maybe somebody can explain grounding an RCA to me, cause I've always just plugged my RCA cable into my headunit and run it to the amps or eq and then run other RCAs to my amps. And then find a good ground with a DMM and cleaned it with sandpaper to get to bare metal and ground all my stuff.

    Re: grounding rca and sound quality

    one common ground is agreeably the best...and prevents possible ground loop noise. I dodnt post the pic, I just showed you what had been done to help prevent a problem... I took my HU (A pioneer) out of the dash and wrapped it the same way, grounding to the case, and I bet 80% of the noise went away... the rest of it, I am applying "Insulators" to the hu where it mounts and touches and metal in the dash. Still need to run a ground wire to my amps ground block, about 3 feet away.

    Are you talking about the back of my HU ? That's my picture. It is a common problem for a ground to fail inside certain Pioneer head units. The ground then goes through the RCA's, instead of the normal ground wire. Therefor grounding the RCA's to the head unit case eliminates the ground loop through the RCA's.
