not sure if you have it all running on the drivers side but its better if you run your rca's on the opposite side of the car, you can get quite abit of interference with the power and rca inputs side by side, its where most people get that whine in there speakers, not really noticable on subs but speakers for sure

just a tip

 

^^ I ran my power wire down the centre console for that reason, and because I got a whole spool of 1/0 welding cable for free and could spare the extra couple feet.

 

Frozen, you should move your RCAs to the center of the car, or the passenger side. There's alot of other power wires that run along that conduit.
