Help, I can hear engine noise thru my stereo... again... :( - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I moved my stereo from my old 240 to my newer one, and after the process was done (took entirely too long :/ ugh, I hate wiring under the carpet!) I can hear engine noise thru the stereo (not loud, but you can hear acceleration between songs, and if I hit pause, etc). I had this problem before, but I'm not sure how I fixed it... I'm thinking it was a bad ground, but that's for sure not the case this time (4ga wires soldered to the frame).

Anyone have any ideas? It's not really annoying, it's actually hard to hear over my exhaust, how ever it does mirror my turbo, kinda sounds like I have a sequential setup, and the spooler turbo is really tiny

Help!

if you run your power wire too close to your RCA's that will usually cause noise. if you haven't done it already, run the power wire down drivers side & run the RCA's down pass. side.
hope that helps.

Yep, already on opposite sides of the car. They're also shielded RCA's just in case

edit: oops, coulda sworn I posted this in tech talk, my bad, mods please move if you feel it should go somewhere else.

Only fix i could ever find for my car was a ground loop isolator from radioshack....

If yours are amp'ed check at the amp and make sure all the connections are clean and separate. I had a huge problem with that, due to shortness of power wires, etc. Like a RCA would dangle over the power and I'd get some noise.

Worse comes to worse, I think you can actually get a noise filter and put it on.

i had this problem in my nissan frontier and i fixed it when i ditched the high-input and went for rca input...

i dunno about the other solutions.. one guy has told me that the noise filter does work while the radio shack guy told me that those things wont work for engine noise.. ?
