Running your power/ground next to each other isn't an issue, if you were running the RCAs and power next to each other, that's a different story.
how do you ground the case? how to you ground RCAs? I might also be looking into a newer aftermarket stereo with 3 sets or pre outs, mine only has 2. Could that also possibly help?
and the power and the RCAs are ran on the opposite side.

Make sure you use shielded RCA cables for speaker hookup and not a single wire with a common frame ground.
Power your amp directly from the battery and ground your amp as close as possible to a frame ground. Use the same gauge wire for positive and ground wires for the amp.
i do not have HIDS haha. Its also the same gauge and grounded AT the battery.
