I just had my system installed, everything works fine and sounds good, well I should not say everything. I am getting a humming noise through my front speakers. My installer figures it is the pre-outs on my amp, we tried a rca noise isolator which worked but totally cut the volume going to the speakers so we removed it. I only get this noise when the car is running.

Do you think it is the pre-outs, and if so what am I looking at to get this thing fixed. Maybe there are other suggestions out there.

Any help would be great.

Thanks

 

- Try a different grounding point for your amps.
- Try using another ground for your cd player, sometimes the stock ground sucks.
- Ground your RCA's
- Try lowering the gains on the amp
- Make sure none of the speaker wires\terminals are grounding to the chassis.
-If you have a seperate EQ,Xover,Line Driver, make sure they have proper ground as well as make sure the chassis is NOT grounded (including the amplifiers)
- Bad\defective\cheep amplifier

Good luck.

 

thanks, how would i go about grounding my rca's?

new to this

 

let me guess you have a pioneer head unit....... you may have to get the headunit serviced, there are issues on the ground side of the rca's inside of the head unit

 

Yes I do in fact.

I am only getting the noise from my fronts, the rears and sub are clear. So I am assuming you have seen this problem before, what should I do?

 

^ Either groud your RCA's or have it fixed\returned/

Grounding your rca's is simply raping a grounded wire around the metal part of your rca's.

 

should i stop using the deck before i return it, i just dont want to damage anything.

 

No damage will occur. I would keep on using it.

 

lol... that was my first question

if you dont want to loose your deck to pioneer for countless weeks then just make a ground jumper from the chassis of your deck to the shield part of your RCA( the outer ring)

 

sounds like a bad ground i had that problem when i was hard wiring my sat radio in!

i learned fast that you have to have a proper ground!
