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

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

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
