HELP PLEASE - Setting up custom system in used car?
 

I recently bought a Mazda MX-5 with a custom audio system (Alpine deck, 2 amps, 2 subs, and component speakers). I tried tuning it a bit but I can't seem to get it right.

I have 2 suggestions:

1 - Does anyone know a site/video I can go to that would tell me step by step how to properly tune a setup like this (I didn't find what Crutchfield had up on their site too helpful)?

2- Does someone, out of the goodness of their heart, want to help me set it up?
I'm in the GTA.

Much appreciated,
Marco
