adding another amp to my system has yet again caused signal problems with alternator whine, i grounded it with my existing stuff, so i dont think its a ground loop problem, my guess is having more power running through the existing wires, so im wondering if instead of completely changing the routing of all my wiring, if id be able to insulate my power wire(s) somehow, i was thinking wrapping everything within 6-12 inches of an intersection with aluminum tape (think tin foil with an adhesive backing) then wrapping that in some good quality e-tape...

anyone know if it would work, or something like this that could work?

i reeeeaallly dont feel like taking the vx apart again to change routing of the power wire
