i have a pair of rockford fosgate p3 12" dual 4 ohm subs at 1 ohm receiving a 1500 watt rms load.

i have a 98 chevy blazer 2dr

my free space works 2 ways, either one is ok w me, whatever makes best spl.

either a mini wall behind rear seats gives me 36" wide 30" tall and 15" deep

or a lay down box gives me 36" wide 22" tall and 24" deep

can someone help me please???

as long as i have a diagram and measurements i can build about any style box

thank you

i dont even know what to do with those numbers, i know what they mean, but, i guess that's why i needed help with design and measurements

music most listened to is metal, but i love the bass and want to compete in spl again.. i hope you can help

a box tuned for spl (38-50hz) won't really keep up with the tight drum kicks of metal music.

when i had my 2.5 ft box tuned to 42hz it got really loud (made your ears itch/hurt) but listening to anything besides dubstep kind of stuff was so crappy sounding i couldn't take it! it was almost like well you ever have a pair of ear buds wear out? when you move the wires and one ear bud would cut out then on then the other would. well that's almost exactly what having a high tuned box listening to metal music sounds like!

i love the Band Tool (love them!) and when i had that box it sounded so bad i wouldn't listen to them.

rite on, well to do spl competition is my main goal.. everything else is secondary.. love me some 5fdp tho.. lol

well if that's what you want, but you Can build a box with interchangable ports. not only will this help you chase numbers but you can build a port with a low tune when your not competing so you can actually enjoy your system!

ya i can build about anything, i just don't have the knowledge to design it to spec and figure out cut sizes

either Joe x or Ram designs can help you. i know Joe can help with a design and cut sheet. but not sure about ram. but ram makes boxes (really really good boxes) and also makes changeable ports.

also bb makes great boxes. some of his work is the best I've ever seen!

ever!

irnlve I will try to help but what kind of SPL setup are you looking for with 2 600W daily 12 subs in that big vehicle, it may get a little loud with some work but a guy with 2 15s on the same power will likely smoke you in the meter if he's decently setup.
