ground your rca's.

I had that problem. Amps had a bad connection or ground internally.

How do I ground the RCA's?

Subject: Re: Noise Sun Dec 30, 2007 4:36 pm

bobby pull ur rca's out of the amp and see if it goes away do u have those amps dasiy chained

Subject: Re: Noise Sun Dec 30, 2007 4:45 pm

bad ground, are you running over 16volt setup????

Subject: Re: Noise Sun Dec 30, 2007 6:18 pm

Are you running a pionner head unit? I had that probleam was a ground in the head unit for the rca's. In fact I had 5 pionners do this. Finally got fed up bought a Alpine have not had a issue since.

Be careful grounding RCA's one slip and you can smoke some shizzzzznit i saw one of my guys do it last week... I about poop on myself. Ive never seen that until the other day ... But it was a little funny.

my was a pioneer also touch the remote wire one day and then noise.
but if you are running a 16+ volt setup i have found it is best to have your 12volt battery grounded to the higher voltage bank, if not you get all kinds of crazy noises.

I can pull my hu out and tap on it the subs go nuts so im guessing its the hu internal problems.The amps are running off an bridge module,not daisy chained.From it one channel to one set and the other to the second set.Im using a clarion vrx765vd touchscreen.

Subject: Re: Noise Sun Dec 30, 2007 9:23 pm

I have my rca's grounded on the back of my HU

Edit: I had the same problem and grounded my rca's and the noise went away.

When you unplug the rca, does the noise go away?

For the record we put a safety circuit on the RCA's. If a bad spike goes through the system because of pulling the RCA's while the system is on or over gaining and clipping the signal it will cause the safety circuit to go. It is not the Pioneer head unit causing the issue ...

I took the rca's out of the amps and there is no roaring,so the amps must not be causing the problem,going to check further today.Im just going to work backwards until i get to the hu and eliminate everything one by one and then try grounding the rca's at the hu.

Subject: Re: Noise Mon Dec 31, 2007 9:57 am

take u another rca and just lay it loosely outside the truck plug it in to the bridge module pull ur head unit out and stick that set in......i have seen those bridging modules fail

Subject: Re: Noise Mon Dec 31, 2007 9:42 pm

like john says .. i had the same issue.. my solution was the head unit but i have also fixed it by swapping rcas. just my 2cents

Subject: Re: Noise Mon Dec 31, 2007 10:13 pm

Try another HU and see if it goes away. I had few issues with Pioneer doing that.

Subject: Re: Noise Tue Jan 01, 2008 2:05 am

I bought a new HU today and it is now cleared up,odd enough,but greatful,put the new Clarion VRX775VD in there,sounds great.Thanks for all the support from all of you on this,I appreciate the help.

Subject: Re: Noise Wed Jan 02, 2008 8:40 pm

well it seems the new hu didnt solve the problem,so now the rca's must be going bad or something.

got to be rca's. if i can ever get time i will come and help you bro.

Subject: Re: Noise Wed Jan 02, 2008 11:14 pm

Get a good set of shielded rca cables. Run it on the outside first to see if that solve the prob. Also, Is the ground from the HU on the factory harness or a seperate ground to the chassy.

Subject: Re: Noise Thu Jan 03, 2008 12:17 am

hey bud im back on the boat,bummer,but the hu is on the factory ground

Mine too, often times what happens is the RCA's in the rear of the car touch a 12 volt positive and this "burns out" the trace inside the HU.

The simple way to fix, keeping your rca's plugged in!!...you take a wire (8" or so) thats stripped back about a full inch and a half and divide it in half.... ah hell easier to just draw it....

De Mui Chingon..... Tell em Zak..

I concure with this man.

Subject: Re: Noise Thu Jan 03, 2008 2:13 pm

its a ground loop the amp is getting a poor ground therefore trying to pull ground thru the rcas

Subject: Re: Noise Thu Jan 03, 2008 4:33 pm

x2 again check your amps ground

Subject: Re: Noise Thu Jan 03, 2008 10:25 pm

I appreciate you guys helping me out on this and i will be trying this as soon as i can get back on land(feb 8th)
