321slapinbass Posted February 19, 2013 Report Posted February 19, 2013 ok so i did the "test", i put a 10" sub inside of a sealed enclosure, wired it to my DD M2 at 4ohms, and faced it towards the hatch. i then got out my SPL-LAB meter and did a frequency sweep with the meter on the dash and everything sealed up. the highest it scored was a 122.91 at 35.66hz. So.... i guess 35hz - 36hz is the peak frequency of the 1st gen Durango cabin? am i right? my 2 15's tuned to 33.78hz are also loudest at 35hz. please tell me if that makes sense, thanks 2000 Dodge Durango Subs - (2) SKAR VVX 15 D2's Box - 7.2 ft^3 @ 33hz, 120 in of port Sub amp - Digital Designs M2 @ .5 ohm Mids + Highs - PRV Audio Mids + Highs amp - Hifonics 2000.4 Headunit - Alpine CDE-100 Equalizer - Clarion EQS746 Batteries - Mopar group 27 + (2) C&D 52ah Wiring - 1/0 BIG 3, (2) runs 1/0 Alternator - Singer 250A 147.79 dB @ 35hz - burp - sealed on dash 147.47 dB @ 35hz - music - sealed on dash YOUTUBE: http://www.youtube.com/user/321slapinBass/videos
