you need a true rms DMM and an amp clamp. hook them up to your speaker wire at the same time, run a tone ,and read them at the SAME time. DO NOT PUT THEM ON PEAK HOLD.
box rise will be different at every freq...it will prolly be at its max a little above tuning. (5-10hz)
okay thans alot marshall your the only one i htik that knows that lol so when u figure this out what should u do change the setting on yor amp to that impedance or what
oh...and incase you didnt realize, your sub will see different amounts of power at different frequencies.
just because an amp is wire to 1ohm and is supposed to do 1000wrms...it will only actually see 1ohm at VERY few instances as the frequencies change during music.
