A buddy of mine wanted to know if he could get 8 12 kicker comps in an extended cab f150 ... the thing is he doesnt want a wall .. he wants to stack box on top of box , port in the middle//.. So a single box on bottom , and another box on top of that one... 4 subs behind the passanger seat, 4 behind the driver... and port in the middle, i told him it was a bad idea and he would probably get much better results doing 4 12s in a single box fired up port forward but he wants all 8..

So will they even fit ?? they require 2. X cubes per sub for ported, and like i said i told him there is NOOOO way your gonna fit 16+ cubic feet in a NON WALL behind the seat.. so what do you all think ??

I have the same year truck and model. I'd go sealed with all 8.

u sure man?? he wants spl .. 8 12s in the cab of a truck SHOULD be loud nomatter what, but those subs ( oddly enough ) require like over 3 cubes sealed..???.... He will NOT do a wall after all ive stressed to him .. he ONLY will do 2 stacked boxes center port .. i have no idea why , even after i tried to tell him i could build him a wall of 4 12's that would destroy what he wants to do .. but its his truck...


He THINKS he has 18 cubic feet to work with , with NO wall And NO sealing up.. ugh , is there anything i can tell him?

12cF sealed would be fine for them.

so i got a few guys now on the sealed wagon... well if he absolutely wants all 8 what do i tell him.... I might be able to sway him on the sealed ported thing , but he will insist on 2 seperate enclosures stacked... so in you alls opinion 4 subs sealed in each enclosure stacked, what should i even start with ?? 4 subs... 1 sealed box at 6cf?

tell him to do less of some better subs to use the space he has.

Tell him to take out everything but his driver seat and he could fit 12 in the bed 8 in the back and 4 beside him...

How many amps?

its just one amp, so i have no idea why he wants 2 seperate boxes... oh well lol.. but if he did go with sealed, u think it would be ok with a single common chamber about 6 cubic feet ( per 4 ) or a 12 cub wall...

And if anyone has any dimensions for the 3 that would help me help him out a ton..

Sealed wall

sealed dual enclosure

ported wall...

im really not sure how much space he has in that truck so anything to start would help out alot

thanks again guys
