Spitfire2k6 Posted July 17, 2010 Report Posted July 17, 2010 Ok 48-10's equal 3768 sq inches 32-12's equal 3617 sq inches 20-15's equal 3532 sq inches 14-18's equal 3560 sq inches OR 8-24" Jackhammers equals 3617 I wondered the same thing as to what was close and wasnt a odd amount of subs to run to multiply amps. you have to take excursion into account too tho... only messin that its nuts haha Live life to the full... Then TURN THAT BITCH UP!

MrSkippyJ Posted July 17, 2010 Report Posted July 17, 2010 Hmm, I will be in Speedway probably Wednesday-Monday, how close are you to there? I need to check this out.

sundownz Posted July 17, 2010 Report Posted July 17, 2010 Batteries are charging and we will do some metering once they are full. We don't expect optimum results as there are 18 sets of Y-Splitters involved -- bet the head unit is hating life Once Hank gets home he is going to use a Maxx-Link at least for a while until he figures out whats wrong with his line driver unit. - Jacob Fuller - Owner, Sundown Audio - Sundown Audio on FACEBOOK - Please DO NOT PM ME -- use my email address -- [email protected]
sundownz Posted July 17, 2010 Report Posted July 17, 2010 We got the batteries up to 17.8 volts and got sick of waiting so we did a sweep : Peaks at 30 Hz ! - Jacob Fuller - Owner, Sundown Audio - Sundown Audio on FACEBOOK - Please DO NOT PM ME -- use my email address -- [email protected]
sundownz Posted July 17, 2010 Report Posted July 17, 2010 Burp - was a bit louder with 156.7 dB ----- Clamping power: 910 watts per amp x 12 = 10,920 watts for 156+ dB @ 30 Hz. We calculated impedance rise to be 3.5 ohms -- also currently we are using 18 Y-Splitters to get the signal to the amps so RCA voltage is really low (line driver not working right now). Hank plans to do more testing with a line driver soon when it gets fixed. - Jacob Fuller - Owner, Sundown Audio - Sundown Audio on FACEBOOK - Please DO NOT PM ME -- use my email address -- [email protected]
EricR Posted July 17, 2010 Report Posted July 17, 2010 I should have posted earlier what I thought the number would be lol, 156 at 30 hz I was dead on. That should go up quite a bit once the line driver is up and running. i was thinking leave the 12 sitting in the box in the hole and duck tape from the bottom of the sub to the bottom of the baffle so the sub doesnt free air. would that work?
