[Big Metts]

i plan on putting 4 18" fi's in a '09 gmc sierra 1500 crew cab i need some plans for a box if anyone has any or know where i can get them thx

[brewer_brewer]

what are your dimensions?

you are going to have to do a wall for 4 18's.

what model fi do you have, how much power, what type of music do you listen to, do you want sq, sql or spl?

[zfrerichs]

what kind of build back seat wall? blow thru? 5 cubes a sub 12-16 sp inches of port per cubic ft is the basic stuff for the btls

[bennett15]

if you dont do a blow through your probably

going to be very tight on airspace back there

well I knew it'd have to be a wall and I was planning on 4 kenwood kac-7204 1000W amps too start off with, kinda broke as a joke atm haven't got the subs yet but 18" fi btl's, going too be little by little build the box get it prepped. I figured I'd go big on a first time big build. I like heavy bass rap like anything coming out lil wayne gorilla zoe etc go a little easy on slang terms kinda new at this learning as I go along. yeah my ideas are all screwed up in the first place kinda how we do it around here

how big of a box can you fit back there.

max width, depth, height.

sound quality, spl (loud) or a both (sql)

[Big Metts]

i'd need too measure it but bout 5-6 foot wide 4-5 foot high maybe 2-3 foot deep and definitly spl

[brewer_brewer]

i would say tune it around 40 hz but it is kind of pointless to tune for spl unless you know what HZ your truck peaks at.

but my box is 52 inches wide. with about 3 inches the spare.
