4 12's

alright well right now i have 2 12" rockford fosgate p3 slims behind the seats of my chevy 1500 single cab truck. i want something louder. so im thinkin 1 or 2 more additional subs in a new box. RF recommends .60-1.0 ft^3 per woofer. the new box i have planned on building is 2.4 ft^3. so if i do 4 of them after woofer displacement there will only be .529 ft^3. but if i only do 3 of them there is .729 ft^3 after woofer displacements. which is in the recommended sealed box volume. so what do you think i should do? do 4 and stuff it with polyfill(would that even help?) or do 3 and do what RF recomends. i pretty much just wanna know what will be louder.

thanks a lot,

*i donno if this helps but i am gonna be giving them roughly 4-500 watts a piece.

so you have 1500-2000 watts to work with. i would go with all 4 if u can cram them all in there and fill the shit out of it. when it comes to sealed, the "smaller" the box the louder it will be. polly fill will bring it down some and alowe you to extend lower

Do 4 with the biggest box possible, and stuff it completely with polyfill.

does it really make that much of a difference? and how do i know how much to put in?

 

[morgans432 10+ year member]

put as much as you can fit. Just stuff it until it starts coming out.

it wont mess up the subs if it gets in them?

 

[atlninja82 10+ year member]

and how much do i need to get? its a 2.4 ft^3 box. i saw some on sonicelectronix.com and it comes in 20 oz. so how many 20 oz things should i get of polly fil?
