Default Hummer H2 4th ORDER BANDPASS 8 nightshade vs2 15'S BY SCOTT BOWMAN

This is on a few other forums as well, was bored, and I'm actually on this site more than smd, so I figured I would post the log here as well. Equipment as follows;
8 Sundown audio nightshade vs2's 15's dual 1ohm
2 audioque aq20k's
2 old school precison power pcx channels
8 kinetik 2400's, 2 shuriken bt120's and one kinetik 2000 under the hood
2 mike singer 350 amp alternators
mla dual alternator bracket
mla missing link module
pair of sundown audio neo 10's in custom doors built by scott bowman
pair of selenium super tweeters
custom a pilars with 4.5 infinity ref comps
q-logic kick panels with fosgate power series comps
one bad as 4th order designed by Scott Bowman and Nick Probst..
a ton of 1/0 welding cable(ofc)
alpine ina w900
cheap clarion eq(but I love it)
Thanks to Jacob from sundown for making a bad as sub, and thanks to Vance Wilkie for installing my alts, and fixing shit that was broken.


old set up




tear down"






Scott bowman

















sketch up of new box




















loading wall
























These are the first subs we tried in the hummer, american bass hd's. They are good subs, but they don't perform well in 4th orders. They have a low qts and are stiff as hell, better suited for ported or 6th order's. Mike Singer had told me this last summer..eventually went to the nighshades




















shrunk the port to lower tuning







best number with the hd's, door open on the dash

clamp numbers with the hd's..a little over 22k ,,a hair under one ohm. funny, clamped about 3500 less watts once we changed subs, my rise went up, power went down, but score went up almost 2.8 db

This is why I changed subs




bad recone, not enough glue on the stitching
Sub blown on 22k - YouTube

new subs





upgrades:

before

after Mike Singer 350 amp alts x2!

H2 hummer 8 sundown nightshade v2 15's 2 aq20's - YouTube

Ty Houstons H2 hummer outlaw testing - YouTube

best numbers with nightshades so far is 156.5 sealed on dash at 41hz? 160.5 outlaw at 43hz, haven't retested since installing the Mike Singer alts, plus Scott is running more runs of 1/0 next week, so hopefully the scores will improve

yes, its supercharged, before I added all the caraudio it was quite fast for what it is, with the weight and the wheels, I'm betting its like a stock hummer again, the charger does help with motor bog from the two alts while under a load from the 20k's
