[QUOTE="microhaxo, post: 5442853, member: 570733"] I measured the watts with a combination of a DMM on the amp and a Clamp meter on the speaker wire from the sub. Amps x Ac volts = watts so 18 amps x 40.1 volts = 720 peak watts take that x .707 (efficiency of amp) and i get 510w RMS Also positive on the ohm.. Wired it Neg to Neg Pos to Pos and Pos to amp Neg to amp. [/QUOTE]
