Hey guys, quick question:

routed RCA's from a new factory in-dash stereo to the trunk for a 4-ch amp (fronts/rears) and 2-ch amp (2-sub)... Get some alternator whine when it's cold out. what's the BEST route to avoid this from happening? I pulled my seats and routed along the driver's side near the doors (which is horrid as is, factory power wires for lights and speakers all over the place).

I'll be upgrading the grounding for the engine first, of course.

 

what head unit do you have? Some have issues with rca noise

the "dont run your power wire and signal wires on the same side" is a myth.

Your getting ground noise from somewhere, where is your ground located?

 

are the power wires ran on the opposite side as the rcas. if you have tin foil what you can do is wrap the RCAs in that - adds additional shielding.
also how high are the gains on the amp set?

 

I'm in the process of redoing my speakers (blew all 4 stock speakers... yay me)... I'll redo all the wiring christmas eve and see if the wine goes away... I need speaker adapters for 6.5's with large baskets... any ideas?

 

you can trace the factory speaker and its plastic housing

then drill out holes that will match your factory adapter

then cutout whatever size you need

Have you tried a new grounding spot??

The rca next to the power wire is not your problem, im runing my rca cables for my sub and fronts right next to 2 4ga wires
