Ground it to the floor. Use to shortest run possible.
Remove, scrape and sand away the paint so that it is contacting clean bare metal.

You lost me on that. Are you trying to install a amp? Or maybe two amps. If so where are you putting them?

I dont know how the crew cab setup is but i have a reg cab and i pulled up the carpet behind the driver seat and sanded and grounded there. a ground wire goes from amp to metal of truck. if you have three amps then you have 3 wires that should be grounded. u can use that nut setup to ground all 3 wires at the same point.

The battery is grounded to your truck...... Or else none of the electrical system would work.

That's what it looks like. A ground lug that you would bolt to the frame or floor.
Then you cut the wire in half (or whatever length you need) and you will have 2 wires with ring terminals to go from the lug to the amps.
For three amps you will have the use the left over wire and add a terminal.

Or you could run it to a good ground closer to wherever you're mounting the amp, it doesn't have to go to the battery. Like TexasXtreme said, ground it somewhere close to where you're installing the amp...just easier to wire up that way.

That's redundant, you're grounding the system twice.

each amp needs to be grounded one time. if i was you i was pick up the carpet and sand the paint off. make sure its metal and bolt the wires to the floor. then run them to the amps..

ok belizeanlow i think you are confused, 12v wire on amps goes to battery, remote turn on to hu, ground to metal under carpet(or wherever you choose). make a grounding point and ground all 3 amps there. run all 3 12v to battery.run 3 remote wires to hu, join 3 wires together and connect to remote lead coming from hu. then i assume you know how to run wiring from amp to speakers and subs.

You don't need separate feed lines to the battery or 3 lines running to the head unit. Just run one wire to each and split it at the amps. Much less wire to run.
