Any Car Audio Gurus Out There?

[rawfuls]

What guage should I be looking at for the dedicated power to the amp?

Looking at 8GA for +12V/-12V, remote turn on wire (is this a special wire? Could I just use regular speaker wire?), and some RCA cables (same with this, regular RCA or special?)

I know at work, we have a huge roll of speaker wire we used for about 15ft for a project.. and we have never needed it since.. I could probably grab about 10ft of it to use on the remote turn on wiring?

In the other forum, a member who used this exact sub bought a few ft of regular power extension cord, and wired it that way.
I feel like this is a really good idea since people are familiar with regular household plugs, and would be able to unplug/plug really easily, in the case that it gets knocked off/whatnot.. In the case that I'm not around to "fix" it.

Though, Anderson PowerPoles, I already have.. and would be a quick and easy way to do it.

Basically, I'd like for it to be easily removed in case I need the extra cargo space.
Also, it'd make it really easy to transfer to another car (when this thing dies).

Any suggestions on the sources of wiring?
I feel that I'm most scared/worried for the head unit installation..
Ripping apart my entire dash sounds annoying.

EDIT: any suggestions for a ported sub?
Debating between the Pyle (Sealed) and DUAL (Bandpass).. so now I'm at a lost of words.
Ported seems to be the king of boomy bass, so maybe that might be what I'm after?
