Alternator Winding.

How can i get rid of alternator winding. My Car Sounds like a Milk Float?

You could try a biggish cap on the + and - pole of your headunit and caramp (if any).

I used to have some whining in my car, a change to shielded RCA's and a 1F powercap fixed the problem

I have just bought a surpressor 3 farads. Which connects to a ground then the cable from the surpressor is connected to the main output of the alternator!!!! Madness.

I#m running 4 JBL speakers on a Alpine MRPT130

And

A Subwoofer running on a Alpine MRV - T707

Will a SURPRESSOR sort the problem out?


Also what about Dimming of lights???? How will i sort that out.

The big cap stops the lights from dimming, since the atternator/battery doesn't see the full load of the amp

Well, to solve your problem...filters or chokes are just bandaids. You have a ground loop somewere in your system. Find the problem first. Check all your grounds, clean up the connections etc. make sure all of your amp grounds connect at the same point...not the battery (clean batt terms/add/cleanup ground strap connections). Also, make sure your using proper signal cables, shielded...away from sources that could give noise...comps/large wiring harnesses etc.


Also, make sure that your gains are adjusted correctly. Make sure no speaker wires are shorting to ground. Check connections at your headunit.

Actually, the battery is the best place... Your going to have a hard time connecting everything to a single point on the chasis... So what if you have to run a few extra feet of power cable.. it should solve all your problems...

will the surpressor solve it (just a quick way)

If thats a capacitor, then chances are no..... A capacitor and a choke might.... or one of those filters designed to remove noise... I'm not too sure whats in them... But, if you have a ground loop, then, you could try a ground loop isolator (if ya lazy) or fix the problem properly.. lol

Well I have checked ALL the cable about 1,000 times as i kept losing my left front and back speakers. They would just die when the volume was low, but when i turned it up loud they came back on. There was nothing wrong with the cable or connections. So i have today bough a new amp £99.99 Alpine - T130.

I would not suggest to run the amp grounds to the batt. Yes, the batt is the best source for ground (it is the source), but unless you mount your amp under the hood, running ground cables will add to your problems...lengthening grounds add resistance...ground loops...different current paths...meaning noise.

You mentioned about the system cutting out at low volumes...sound like a connection problem to me. Cold solder joint or a short somewhere.
