Appreciate the help guys. I've had to put off my project due to school/finals but now that summer has come I'll pick up where I left off. The plan for right now is to map out all my electrical needs and cover my car with some deadener (second skin damplifer pro). As far as wires go I see you all favor the knukonceptz so I'll have to check them out over stinger. As for everything else I'm still planning on going with monster cable. Here's where it's still fuzzy. I'll be going with their 400 series with their 2 channel rca's for my mono amp and 4 channel for the 4 chan amp.

Then how much speaker wire will I need? The speaker wire runs from the 4 channel to each speaker, correct? is it just one strand of speaker wire or more per speaker?

Also, I'll need a distro block to connect the two amps. The monster cable distro block converts 1/0 to 3 4awg. How much of the 3 4awg will I need to hook into the 4 channel amp?

As far as box building I have little knowledge. What exactly do you mean when you say 35-50hz?
