[QUOTE="ado, post: 5666849, member: 603881"] There was already a hole in the frame, it is on my pass side. Then ran that wire to the seat bolt, then my back battery is connected there along with my two amp grounds. You need a clamp meter to set the gains properly with a dmm. You need to clamp the meter around one wire going to the sub and get your current (amps). Then measure your output voltage (VAC) of the + and - of the amp. Multiply the two and that is your power (Watts). VAC x AMPS = Watts It is best to do this while playing around a 40-50 hz test tone. [/QUOTE]
