Wire the front channels to increase the output power from 70 watts to 200 watts per channel. Try the 4 full-range channels and a subwoofer channel or the 2 bridged full-range channel with a sub channel configuration.

Enjoy the powerful sounds that come from a sleek little amp, the Polk Audio PAD4000.4
