Wiring Question

[dacfleming]

So I am running a 4 channel amp,

I am looking to run my MTX Terminator Sub As well as my speakers.

I've never done anything before with amps, although I know how to do speakers.

I am assuming that the Sub gets its own channel, Which speaker should get which channel?

(I have two front doors, and two rears)

Secondly,

How do I know whether or not that spot that I chose to ground my ground to is a good enough ground?

What resistance coils does your sub have? If it's got dual 2 ohm coils or is single 4 ohm, you can bridge two channels for the sub and run your speakers off the other two channels.

Google how to bridge an amp and do some research. Lots of people do this with low power audio installs. There's lots of information sitting around the web waiting for you

Single 2 ohm, no I wouldn't recommend bridging the amp for that.

You can get a cheap little Boss or Planet 2 ohm stable monoblock amp though. $54:

Boss AR1500M 1500W Monoblock Armor Series Class D Car Amplifier

Okay cool, And I would just use that monoblock amp to jump power the sub, and my other amp to power all speakers?

Where can I buy splitters for the power cables for the amps?

"Jump power to the sub"?

Yes, monoblock for the sub and another amp for the regular speakers.

Ebay would probably be the cheapest, but you can browse on Sonicelectronix. They're called "distribution blocks"
