Advice on installing an audio setup in a '07 Silverado Extended Cab? Parts guide?

by "bridging" the subs puts them at 2 ohms. by doing it parallel puts the subs at a 4 ohm. you'll have to check the rms output at both loads and see which one works for you. what kind of subs and amp do you have?

oh my god! someone pm'd me and helped me fix it! thanks!!
I took the amp ground off the seat bolt and held it to the door latch on the side of the car, and it stayed on! I turned the volume up and I could hear bass!! It was awesome! Turns out it was that after all. All I have to do now is fine a place to ground it. Every bolt and piece of metal inside the car (what i had it hooked up to before), has a white paint coat over it. Im guessing that takes away the grounding. So not sure what to do from there.
And does anyone know anything about this? I dont know how. Not sure if I blew it doing all this, or did it a while back, but my rear left speaker doesnt work. Can I use the front speaker I used to use (factory), and hook it to the back? Or are the rear speakers different than the front?
So all the questions I have left for now (bc im hard to understand sometimes)
1.) So my sub and amp setup is good? Someone had pm'd me it wouldnt work. Heres his PM:
2.) Any suggestions on how to find a good spot to ground my amp? The amp HAS to go under my front seat, and the ground cable is about 3 ft long.
3.) Can I use my front factory speaker in the back? Do you know anything about that?
Thanks a lot! I imagine Ill run across another problem tomorrow, but hopefully not. I'ld appreciate it if you could help me then too if I do run across something again.

Ooohhh its kind of a mismatch there. That amp is too much for them subs. You need 2 subs with bout 300w RMS. That amp can either run 500w or 150w to both subs. If you hook them up at 2 ohms this will put out 500w RMS and thats too much for them subs.
If you hook up them subs in parallel that would put a 2 ohm load which would make the amp put out 500w RMS, the subs are only rated 300w total RMS together.
If you hook up them subs in series, it adds resistance or OHMS. Since I am assuming you have single voice coil subs, this would put them at an 8 ohm load which would be about 150w. Only way to work it to put a 4 ohm load is if the subs have dual voice coils at 2 ohms each. Thats what I mean when you shop around for sub equipment you gotta match it close so you can work with it.

sorry, forgot to answer your question s34n. its a 1 channel amp I believe. This is my amp:
Alpine MRP-M500 Mono subwoofer amplifier — 500 watts RMS x 1 at 2 ohms at Crutchfield.com
These are my subs:
Kicker TC10 Ported truck enclosure with one 10" Comp subwoofer at Crutchfield.com
I have two subs in total, so that amp and my two subs should work fine right?
