How much RCA cable do I need?

[speedyjuarez Premium Member]

Okay so I'm going to do some upgrades and add to my system. Incase you want to know I currently have two 15s bandpass 4th order, one BRX 2000.1D pushing them. A singer 275 amp alt under the hood. A mulit amp wiring kit from kicker 09PKD1 1/0, and one yellow top battery.

So I Plan to add another BRX2000.1D and two more 15s 4th order bandpass. And add a second yellow top in the mix.

I plan on adding another run of power wire to my power distro block, and running a new RCA interconnect to my amps. Then RCAs I have now are monster cable but I had to add an extension after relocating my amp.

So my questions to you guys

1. Should I upgrade all my 0 gauge power wire from batt to distro block to copper instead of aluminum?

2. What's the length of RCA I would need to run for a 99 Tahoe from dash to cargo area? and would I have any drop in quality, strength or something running a long RCA?

Thanks again for your input.
