since I dont really understand this and I have no clue what to look for what is the smallest gauge of wire could I use to safely run these two amps?

Amazon.com: Kenwood KAC-7204 1000-Watt Max Power Stereo Bridgeable Amplifier with Variable LPF/HPF: Electronics

and

JVC KS-AX4302 2-channel car amplifier — 100 watts RMS x 2 at Crutchfield.com
