What kind of copper cable do I need for an 8 gauge amplifier?
See attached photos for a real 8 AWG Rockford Fosgate pure copper cable (left) vs. BOSS cheap copper coated aluminum undersized cable (right).

What kind of wire does a boss Kit use?
What BOSS are giving you amounts to a 10 or even 12 gauge copper wire. Aluminum does not have the conductivity and thermal capability that copper does so you already need a thicker cable to match a true gauge copper one. It is especially alarming that the gauge is not true on any of the Boss kits as well as using coated aluminum.
