    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

    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

    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

    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.
