I could use help with my subwoofer now. Remote wire is working correctly, it is connected to fuse box in rear.. The RCA's are connnected to the rear of my pioneeer head unit. The Ground from my aftermarket apline 850 amp is connected to the same bolt as my ground from my battery is connected to. And the positive from the amp is connected directly to the positive post on the main battery.

The subwoofer makes a humming static noise when turned down low and even continues to make the noise after I turn the subwoofer to off on the headunit. No fuses are blown, all connections are tight and secure. amp turns on/off along with ignition. door and reardeck speakers work correctly. subwoofer is wired correctly to amp.
Sounds like interference with RCA's or a ground loop/bad ground. Make sure you aren't running your RCA's near your power cables or the factory power cables. That will certainly give a humming noise if that signal cable is picking up interference from the power cable.

And as far as the ground, if your ground cable is running back to the battery ground post anyways, you may want to think about just grounding it directly to the battery - which is what it is doing anyways, just through that bolt. You could add a terminal to the battery post... here's what I did...

Grillcraft SW grill / VIP300C eyelids / HID lows & fogs / LED halos / IPCW tails
SRT8 front lip & rear wing / 15% ceramic tint / JL Audio sound / BT everything
Trinity / 180 tstat / AFE CAI / MF hi-flow cats, mids, catback / DMH cutouts
MOOG suspension / R1 Concepts brakes / 20" Konig Blix 1 / Kuhmo 275/45/20
