Default Need help with building a sub box (to SPY or anyone else who can help)

ok, this is my first post here. i have a 1983 Chevy S-10 reg. cab, im getting ready to buy 2 18" Fi SSD subwoofers and im going to do a blow-through set up in my truck bed. The max dimensions for the box i have is 39"Wx60"Dx14"H the subs will be facing up and there will be a port going into the cab. i would like to have the box tuned to 32 or 33hz. what would be the final dimensions for the box and port. I would like the box to look something like this but it dosent have to. ive built many ported sub boxes but never one for 18's. any help would be great! Thanks!

how can u mount them up bro.. not gonna happen


assuming u were going to give the BTLs 2000w rms per sub... thats 4000w total, just divide that power between more lower end subs

with that height restriction of 14" u should do 6 12s

u cant just have ur port firing into the cabin sealed off and the subs firing into the bed of the truck whether u have a cover or not

the sub and port need to interact in the same airspace for a ported box

15's probably wouldnt fit either because the box will have to be at least 17" tall with 3/4 MDF
