engine whine

You could have a bad RCA cable. The noise went away after you fiddled with the cables, try wiggling them at the amp.

yeah i would, u don't run rca's with power cable, but i think u just may have a bad rca, that is what happened to me, one of my rca plugs went bad and my engine whined, i only get engine whine from my AUX cable now when it comes loose, so if you have a loose wire that could cause a whine.

I just ran into a problem with an airbag sensor that was making the noise in my setup. The RCA cables ran right next to it. They lasted for about a year then started giving me engine noise. The RCA cables were ruined, every time I plugged them in the noise would be there. Took the monster cables all the way out, put them on the ground and they still made the noise when I plugged them into the amp. Plugged in an old spare set, and the noise was gone. I went with coaxial cables for now and moved them towards the middle of the truck. I worked on this problem for a long time, checked every thing at lease twice, changed grounds, added grounds, changed where my power & ground was coming from on the headunit, but in the end it was the cables that were fried. I believe the yellow air bag sensor caused my problem.

sometimes the outer side of the rca can touch the amp and make that noise too.... ppi amp did that to me.

ugh be such a pain to rerun them lol

I tested it by using my phone as a source with the aux to rca cable. To remove the rca cables from the confusion, and see what if any noise is there.

Seems to only whine sometimes

do you use ur phone as audio and do u do it through bluetooth or aux cable?

 

[chuckwnorris]

I use a phone with mog, with a aux cable to back of deck. (mini headphone jack)

When I was trouble shooting this helped me to eliminate possible problems with noise from deck or RCA cables. I switched amps as well trying to figure it out. I don't have a bluetooth option on my deck.

cool, i use to use MOG, i loved that, i just Google Music Now, i always got my engine whine from my AUX cable, so that is not your issue?

my system is all good now. I ran into problems and it was all my rca cables. Monster 4 channel set, and a xln monster set for the subs. All of the rca cable's made noise when I plugged them into the amp, even after I took them out of the vehicle. The problem was the air bag sensor, makes a high pitch noise, and some how made these rca go bad. It took almost a year until they made the noise. Never had rca cables go bad, so it was a surprise.
