[QUOTE="rtscout, post: 2230471, member: 571167"] Nope. The RCA's don't ever get near any power wires. I also have an MTX 4240 hooked in; I have both amps grounded together under one bolt (both ground wires are less than 12" and the ground is to the body and clean) - I've read that this is the preferred method, but I've also read that they should have separate grounds...?? I suspect it may be the HU's ground... and I've read that this ground should actually be extended all the way to the amp's grounds to ensure they are all at the same potential, which goes against the "shortest ground" rule. Lot of conflicting stuff out there. [/QUOTE]
