For sure. Just gotta figure out which route I will take. Nearest scrap yard is 45 mins - 1 hour out from where I live, and I'm having little luck finding someone I know who makes custom boxes. But I think if I do an 8 inch there and figure out how to replace the center console sub and with what, that'll suffice for me
I posted this before and copied this over.
I have bought several enclosures, and IMO they ALL seemed a little cheaply made to me. Every where I looked for an enclosure at least 1 dimension was always at least 2 inches off from the size I wanted. I was looking around to get some completely custom boxes for my regular cab pickup so I could keep the seats all the way to the back, and keep the center storage area. Every audio shop in town that actually made them wanted $500 or more. I searched around local to just try and get some custom sized cuts made so I could assemble them myself.
Lowes and home depot only do straight cuts, and aren't guaranteed to be very exact with size. I really like ACE; at least around here, everyone who works at ACE has another job that they do, and uses ACE to network. I was trying to see if they would make me some custom cut sizes so I could build my own boxes. I show the guy I am trying to get some custom cuts made, and he tells me one of the other guys does cabinetry work and could probably help better. After talking about for 20 minutes, he tells me he could make them.
He made me TWO boxes out of 3/4" mdf to the exact measurements I wanted the outside to. All sides were within 1/8" of an inch, perfect: cuts, corners, angles. Screwed the sides together with some perfect angle tool, braced the edges, glued the sides together to seal it, the entire thing was sanded down smooth, and he cut the speaker hole. He would have cut out the terminal cup if I wanted him too, (but I went with just tap-in terminals instead). These boxes sure seem perfect for what I was trying to do, and much better quality than anything I could have made. He did them in two days, said they took him a few hours. Charged me $100 for TWO single 10" enclosures ($100 total). These boxes were perfect size, and much better quality than anything I have bought prefabbed.
I would suggest to anyone looking for a custom/unusual sized box where you just cant find what you are looking for, to search out for someone who does (kitchen) cabinetry (a sub box is just a cabinet with a hole), either on Craigslist or through a local hardware store, or someone you may know.
I still think you need to reconsider moving the jack mount. Not sure what reason you have for keeping it there, but its really going to limit you. That's such an incredibly minor thing to change not sure why that matters.
If you're on this site, then you're probably already prepared to change your vehicle some how. The engineers didn't design YOUR vehicle, for you. They designed it within budget, and for the majority of people. I really do think you will regret not taking out the jack mount so you could design a better speaker enclosure the first time.
TO ME: Not taking out the jack is the same as saying you can't add a water softener to your home because it didn't come with one 40 years ago. Or your not allowed to remodel your home, because that's not the way it came. I've said it twice, that's enough convincing for me to try, its always your call.
