16 sierra crew cab

[cjohnson547]

Hey guys, been outta the stereo game for awhile now and I am looking to build an under seat box in my 16 sierra crew cab. I was thinking about four 6.5s ported, two 8s ported, or four 8s sealed what do you guys think would work best? Im not to savy with designing boxes so any build logs or sketchups you could send my direction would be greatly appreciated

I was going do 8 6.5" subs two people said not to do it output wouldn't be all that.im in the same boat as you , I'm going do two 8" ported, maybe down the road 4 8" sealed

Any clue how much air space we have to work with?

Not sure on your truck mine a 2011

guess i will have to build it up and see what i come up with before making a decision. thinking about glassing the bottom to get a little more airspace

[dolarbilz]

I wouldn't waste money on glassing whole bottom..lot of money to gain not much airspace.i have a design for two 8" ported box. Specs are for sundown sa8 if you want it.youll need to measure to see if it fits

Yea if you could send it my way that would be awesome
