I used to have a whine too, but I bought a ground-loop suppressor (basically what Kicker said) which goes between the rca's for the amp and where they plug into the stereo, I guess they will cost about $20 over there.

 

try some better grounding on your stereo chassis and your amp
dont use a supressor if you can avoid it

also check your battery is in good condition.

the only way you can tell if your ground is good is if you take a volt meter to it....it it doesnt read the same amount of voltage that the power supply thats where your wine is coming from....check the voltage!

 

thanks guys. i'll check out my battery and my ground. taking the voltmeter to it will really tell? meaning i have to have everything playing and checking the ground...i'll check it tommorrow morning.

thnx guys.

 

Long, I have a competition SQ setup in my 1997 tibby and you should have no need for a supressor.
Just make sure all your grounds(headunit/amps/caps/everything) are to bare metal and as short as possible.
If your remote turn-on wire is feeding more than one thing make sure it is fed through a relay.
Try to avoid using any of the existing car wiring for power, run your 0 gauge to a distribution block and use that to feed everything in the system.
Seperate speaker wires/RCA's/Power cable from each other - run one down the middle and others down each side of the car.

Hope that helps you.

barry thanks.
i have my 0ga running down the middle into a fused block.
then two 4ga running down the sides. one into a fused block breaking off to for 8ga.
and the other going into a reg block and im only using one 8ga out of that.

i have my three amps, compressor, ps2, screen, pressure switch, etc all running from the blocks.

my remote turn on wire is used for all three amps and i havent installed a relay. i'll do it this weekend. the deck ground and the ground for all the amps are on bare metal. could it be the deck itself?

 

that happened on my old hu...i was taking it out of a car and putting into my current one...and when i put it in i got the squeal....come to find out that the rca's on the hu were shot..i dont know how...but they were. anything is a possibility!
