TaylorFade Posted July 8, 2014 Author Report Posted July 8, 2014 Thanks for the words, guys. And your insight, Ninja. There were a couple of anomalies in this testing and a margin of error is difficult to predict in SPL testing like this, but if you consider the bulk of the data and assume a +/- .3dB margin of error on burps and +/- .5 on the music runs... things get put into perspective. It's difficult to eliminate ALL variables in SPL testing. But I try. Also... a lot of people have asked me why I didn't include a brick of caps in the testing. Well, frankly it's because it would draw attention away from the results- because a brick of caps would skull drag any of these batts on burps. Including the bank used for the control. But for the sake of data, I did an amp roundup a couple years ago and I tested batts vs. caps. Batts were an Odyssey pc2150 (which is easily on par with the very best G31's) + an XS d5100 underhood. Here are those results. This is a traditional clamp NOT on peak/hold. Rise was ~ .9ohms. AQ2200- 2,538w @ 11.4v (batts)- 3,365w @ 13v (caps)DD M3a- 3,657w @ 11.2v (batts)- 4,088w @ 13v (caps)RD D5 - 3,898w @ 11.1v (batts)- 5,355w @ 13v (caps)B2 Audio Zero5- 4,052 @ 11.3v (batts)- 5,355w @ 13v (caps)About 1dB louder across the board. Batts don't want none.

Batts don't want none. And that was 12 total caps right, you call a brick 2 banks of six? Blue or black? I don't want to draw attention from the thread topic, but do want to clarify. "Clipping" is the biggest forum boner now. It's like witchcraft... it automatically explains just about everything people don't understand.

TaylorFade Posted July 8, 2014 Author Report Posted July 8, 2014 Yeah, a brick is (12) total. So, (2) banks. And actually... that testing was done on two banks of (7) so reserve was lower. I had them bussed in 7's so we could do 17.5v testing on the D5 and Zero.
Bass head 4-15s Posted July 8, 2014 Report Posted July 8, 2014 Thanks taylorfade now I know what I need to do,and thanks for the demo a STC am the black guy that walk up to you and shook your hand. Man that is one loud ass truck you got now I know how 155+ on music feels like.You know I won 1st place in my class 751-1500 stock 152.3.
