Hi all,


New here so let me ask my first question!


First off let me tell you about my car, 1995 Maxima GXE 70,000 miles Auto, JWT Intake, Apexi Exhaust, some basic exterior mods, nothing real fancy... but my problem is i get a strange noise thru my aftermarket stereo (Pioneer Head unit, Pioneer speakers, ADS PH 15.2 amp, 2 JL subs) when the volume is down, you can hear the car accelerating in a high pitched noise thru the speakers, it ONLY does this (or notice it) when under semi-hard/hard acceleration, and you can hear some interference I guess when your just sitting still, it only does this when the engine is on, if you put the key on the electrical setting only there is zero noise.. so im not sure if its a ground or something.


Just wondering if anyone has had this problem before.




Thanks,

Justin

 

It's called engine whine, or alternator noise. I have the same problem too, but for some reason the stereo shop has failed to locate the problem. The installer seemed to think the problem was the close proximity between the radio, and the heater controls, which might be interfering with each other, which is bogus. Their install is warrantied for life, but I have yet to eliminate the problem. I've had the stereo system for 9 months, and haven't returned since it was first installed.
