Speakers Whine /altenator Noise

[08r3308]

i have tried everything new deck , new amps , new battery ,new grounds , new cabling , moved amp around.... reinstalled while system twice and no luck its still there .

As soon as car is on its there , i switch the lights on even louder.

Anything anyone can suggest to get rid of it?

Could it be my alternator ?

I have had the amp installed professionally and even that didn't help , took it back fiddled with it and in end turned gains down way too low and even then it was still there.

Im willing to give $50 cash to anyone who can solve this problem.

Mate,

I have a guarateed cure for you. It is a bit old school but it works.

Here is what you do:

- Get a large steel shacle. About 2 - 3 inches.

- Then get about 8 or so metres of 16 guage insulated cable.

- Start threading the cable tightly though the centre of the shackle and wind it tightly through and around, throggh and around, the entire circumference of the shackle. The idea is to imaginne the shackle as a circle and you are covering the circle in several windings (or turns) or wire.

- Connect this wire in series with the 12 volt input of your amp. (add a fuse if you like).

- Start engine, turn on amp, and listen to whine-free clear sound.

If you have a massive sound system, which I suspect you do, you should use a higher current cable, and a proportionaly larger shackle. What you are doing is creating a large inductor to attenuate the whine.

I had EXACTLY the same problem in my R33. I made one, and installed it in the boot. Like I said, it is very old school, but, it works.

PM me if I have not described the process well enough, or you need more info.

regards, Steve.

Are you running power straight from the battery to the audio equipment? might be enough just to have the headunit drawing power directly from the battery, should get rid of the alternator whine.

h/u is alpine 9887 they have something along the lines of a noise suppressor on battery cable so i don't think it would be that.

i will try to run a wire direct from battery to h/u

zonbie you have pm

hey mate if you are running your power wire from your battery on the same side as yur rca leads for the amp seperate them from each other my car did the same thing and i moved my power wire to run down my left side of my car and my rca leads down the drivers side and it fixed the problem

today i gave it one more try , added a noise filter to the constant 12V line to the battery. That solved my issue.

There is maybe a bit more whine but nowhere near what it was before , i guess its stuck in my head now .

But its gone no more whine

btw where did everyone ground their amp , pictures that would be great
