[QUOTE="PioneerSPL1990, post: 5604136, member: 604911"] yeah he measured with a 45 hz signal if it was more then you should be wining becouse with the lower fq his numbers were probably less than the what the amp was actually doing, just slightly. and that is for AC but thats only like a 250mV difference on the scope. close enough your test probably isn't any more than 300-400 watts off and probably for the better anyway. plus his resistance was higher than what most subswould present bay around .6 ohm-.8ohm. which also makes the true number higher. i was told by my electrical engineering proffesor to try a water heater element for the load, to dissipate the heat and handle the 4000W but i'll have to research it and have him explain it better. he said i might be able to do it sometime in the next couple weeks so i'll post the results when im done. and his voltage dropped, he was only on 4 ga as well...... these amps have the balls. its almost put my pioneer's VC into the magnet a couple times and that thing has +3" P-P in it.
