fiq blow through S10 2002

[ncc74656 2]

a friend wants a fi q 18" in a blow through box in his S10. my thought was to build a box in the bed with a collar of linexed MDF into the cab. once i have the box built then i would build another box over it to span the distance of the bed rails and help weather proof the box in the bed. a ZX1500.1 will be his amp with a 220A mechman alt and a XS 2500 battery.

 

he mostly listens to chilly peppers, some techno, basically what ever pandora throws on.   to that end i think the sub might do well tuned a tad higher than 32 but what are your thoughts? 

 

is there anything that most people over look when building a blow through?

if you plan to use acordian boot, round out your metal corner cuts cause that boot will not seal good on 90 degree cuts ...

Does he have a bed cover ?? ... and I'm thinking that a 18" driver will need to have a good bit of angle on it to fit below the bed trim line ...

Extended cab or single cab?

its a single cab. my thought was to build a flange that extends into the cab and have the sub and port on the box wall maybe 3 inches before the bed hole starts. as it stands i will need to cut the bed rail out and then weld in some steel to raise the bed rail about 5 inches to accommodate the sub. the sub itself has a larger O/D than the bed rail is tall... 

 

basically my friend has an extra 4K that he wants to dump into a stereo. last time he had extra cash we build him a 5K dollar computer with an intel extreme and 5 SSD's in raid-0. this time round he wants a sound system that will beat mine. he even suggested buying 2 sp4's but outside of a 4th order i do not see any way to fit them in there. unless he buys a new truck...

 

i have never built a box like this before so its a learning experience for me as well.

why a q?  a band pass would make the most sense for a blow through.

he is looking more for audio quality than spl performance so i figured a Q would fit better than a SP4 or BL. i thought about a band pass, figured a standard ported box for a Q would give him a wider frequency range than a band pass would. if he wanted 2 subs then that would change things i suppose.
