I recently pulled the trigger and cut my cab/box so I could do a blow through on my S-10. Originally I was going to do a hole large enough for 4 10's facing forward ported then decided that the hole would potentially weaken the front of my bow and cause issues with the way my hard shell is mounted. So I decided to go 4th order and only make the hole large enough for the port I intended to use.
I am really impressed on how much louder these subs are in this box. I think I did a fairly good job on the design/build of it, still need to do some finish work. Previously, these subs were in a 5 c/ft sealed box in the extended cab space, I wanted to reclaim my cab from the box and up the output at the same time, I think I accomplished my goals.
My g/f was leaning in the drivers window after I got it tuned and I was just starting to hair trick her, need MORE POWER!!!
I am wondering though on my tuning. I tuned the box to 45hz and from what I can judge with my ear off test tracks, my peak is in the low 50's. It plays the upper 80's nicely and drops into the upper 20's on the low side without a complaint.
Eventually I want to change the subs out for a pair of FI BL15's and up the Power to about 3k clean.
Oh, FYI, the box itself figures to 15.25 c/ft internal and I positioned the baffle so the sealed side is just over 5 c/ft, the ported side figured to 9.46 c/ft. The port is 17x9 (internal) and is 11.3" long.
