set 2 new personal bests at the showdown 150db @ 490w , and a new spl best on music at 157.xx db/ 2800w as the amp died , never even got to turn it up , it apears the driver board died as the amp doesnt go into protect it just flashes the clip and protect light once its outputting a lil bit of power , amp is on its way back to taramps and will be replaced, cant wait for the new alt so i can get that in and install both 8k's
-
heading to the showdown in 4 days got a single 8k installed lot more power now with the smart series amp, didnt have enough cable to install both amps so will install the second after this show/comp

i so cant wait to get this on some real power

saving the deafbonce 16k's for when i make the move to 4x 15's picked up 2x big boss 8's to run on the 12's ,
going to wire 5 coils per amp in parralel for a .4 ohm load. could have ran a single deafbonce 16k but that would have put it at a .8 ohm load and dont really wanna drop that amp below 1 ohm

shes startinmg to get really windy now
i got it about 60-70% sealed off to the cabin right now , and this clip was shot while using the recoil amps so im getting 450-500watts per sub, cant wait to see what she does at the next comp when the deafbonce 16k or 2x smart 8 basses go in

not getting the taramps
2x deafbonce 16k amps inbound instead time to get loud

big update today i went up to jones subwoofer solutions today to do some testing and learned alot
first up we did some testintg to see impedance at various frequencys
starting at 50 hz imp is 1.6 ohms @ 40 hz were at 2.8 ohms and at 30-20 hz were holding on at anywere from 4.0-4.4 ohms
so we put this think on a meter as well
20 hz burp netted me a 150 on the glass @ 372w per sub
30 hz burp netted me a 153 on the glass at about 450w per sub
some changes ill be making
im currently running 113 sqinch of port at 28hz tuning
im going to redo the port to around 175sq inch with the low tuning
#2
need more power and alot of it
recoil amps are comming out and at first im going to wire all 5 subs series parrel for an .8 ohm load on a single md12000.1 half ohm model , at some point this season im going to add a second matching md12k and wire 5 coils per amp at .4 ohm
#3 need to finish sealing the wall , but along with this i am doing a wood roof as ive already separated the roof skin from all the supprt braces , while im at it im going to do a wood floor as well
with theese changes ill be looking to be a solid competitor in monster and cyclone/typhone classes

-

bassed on v3 specs im going to guess ur going to want 3cft net and about 46sqinch of port , though u have room to play with port area , less sqinch of port = less port lenght so u can use that to play with ur box design to get it to fit int he car nicely , i would stay within the 36-50sqinch's of port though andthing smaller then 36sqinch is likley to have port noise
-
i also vote for last box design
3x x8's should be p retty dang loud i ran 4x e8 v6's for a while on 2 x 1200w amps and they got loud if i had to guess id say a solid 145ish in my car i never did get that setup metered before i went to 3x 12's in the trunk and then 5 12's in a flatwall int he same car
my e8's were in a 4cft net box with 36inch of port area tunned to 32hz

been a while but heres an update wall is repaired and holding so far though i did burn up my headway bank so i havent been able to give it fuull power yet .that being said i have 296ah of lev60 on the way along weith enough headway to rebuild my bank into a 128ah bank ontop of the 296 of lev60. my next basswars even is comming up on the 4th so well see how she does im looking for atleast 5db gains over what i put up with the leaking wall last time

Might be time to use some metal along brackets along the long sides along with 90s to add more surface area to glue to.
my thought/plan atm is to cut some 2x4's to glue and screw in there , the rear wall is on a 13* angle so im thinking about rippipng some 2x4's on that 13* angle and glueing/screwing them to the floor and the back wall , and i can go 2 layers high which should be plenty.

took 1st place in mod 10k yesterday at the USACi show and got edged out in street beat 3
ended up doing a 151 musical average using the streetbeat track #10 which plays in the 20hz range
and then tracks 8/9 ( 30 hz range ) got me a musical average of 155
i paid for a rerun just to play track 10 and meter it to see what iwould come up with
heres 2 of my favorite clips i recorded from that show yesterday
