okay i tuned my JL 1000/1 to put out 500w rms to my 15 SE for now... i tuned at 50hz and turned the gain up until the dmm read almost 32V. now thats appx 500w at a 2 ohm load.... however today i hooked the dmm up to the amp as i turned the volume up to the same level i tuned at but a 40hz tone and it read 37V. thats 684w rms. (by the V^2/load formula) then i turned the sub level to 5 out of 15... the reading was now 60V which by that formula is 1800w rms. whats the explanation for this? an SE should blow instantly with 1800w rms clean. and if it was 1800 from a 1000w amp then there would be clipping too... so im pretty postive it wasnt pushing 1800w.. but is it because of the impedence rise ? or whats the reason this is happening? the sub played it clear and very loud. i just wanted to do a burp and see the results. i dont play it like that daily...
note: i tuned with sub not hooked up as JL tutorial says. and these results were with the sub hooked up...
