OK so Ive been needin to build a box for my sub since beginning of february. As I had my amp installed and had the sub...just never got around the the box. Well now I had a hand and some time n dedication and well heres the result so far!
#1- Cut 3/4" MDF sides, back, etc.
#2- First stages of assembly
#3- Now with the slot installed
#4- Closeup
#5- Same thing, diff angle?
#6- Cut cross bracing
#7- JUST after cutting the hole for the sub
#8- Love this pic, shows the size ratio

obviously after being sanded to fit
#9- With cross bracing in
#10- With the lid on
#11- Straight up nearly finished
#12- Full pic, all woodworking finished carpet going on tomorrow
#13- The cover for my truck box, needed to cut section of 2x4 out so i can fit the sub and grille, the box fits snugly in between the far left 2x2 and cut up 2x4. Its also being screwed to the lid and the lid is bolted to my box so no theifin without a crowbar and even then it will be hard and better hope i dont catch ya with my 2 way alarm!
Well thats my box, SO FAR. I have carpet going on tomorrow I HOPE and wiring and sub is going in PERMANETLY never coming out unless I burn it up (doubtful). OH and its being powered by an Alpine MRD-1001 V12
