well the time came to step my system up to the next level and another upgrade is in the works heres a bunch of pics of the box build and heres the specs the box is 6 cubes of air comon chamber poreted to 35 hz[wish i woulda tuned it a littel lower] but heres all the pics from start to finish and the amp is only temporay and also the subs face the floor to make it a littel harder for the sumbags

 

Ok so I have 2 quick questions!! First is your 12s dule or single voice coils? Second is your amp 1ohm stable when your bridge it?

 

I think those subs are dvc. Setup looks good, I know a lot of people don't like kicker and especially the square subs but they still do sound good and can be had cheaper than about any other brand if you know where to look.

 

I have no issues with the subs if there what you like but I was gonna say is if you can you should run your subs bridged and when you hook the speaker cable up run pos to pos and neg to neg so both voice coils are powered.. and if you build another box and this is just my thoughts but you should divide the speakers and each speaker should have its own port when you run high power subs and they hit the air in the box and act like a wall making the subs fight each other. again this is just from what I have learned from building boxes and a lot of comp grade systems.

 

ther dual 4 ohm wired down to 2 ohms and i was gunna do a split chamber but didnt have enough wood and its nothing to crazy i have a littel amp on it now but i plan on runnin something in the 1000 rms range i dont do comps and it fits good i can put my seats back the only thing i have to complain about is the sq of the square arent amazing but other whys im happy for haveing less then 500 in my whole setup

 

dual 4 should be tuned down to 1 ohm. you really need a 1 ohm stable amp to get the power you want. if your running 2 dual 4's at 2ohms your gonna run into problems or blow speakers. and as for what mikey said only time you will have problems with a shared space box is if you are running 2 diffrent subs or running 2 amps to each sub.. if there not phased together then you will blow out 1 speaker which will make it blow out the other! nice setup man im about to put a wall in my truck and 2x kicker l7 15's on a 2000w @ 1ohm amp!

 

thanks man its takin me a long time to get it were its at today and dam i need to check my self on the ohms stuff lol it dosent run my amp hot or anything and iv had the amp on them for about a year and half in the old box ther dual 4 ohm and i have the posative on coil one hooked to the negative on coil 2 and 2 l7 15s is gunna be crazy my 12s are loud i cant imagine 15s
