Hi SMD Forum. I am a long time lurker first time poster! So here's the deal, I'm currently working on building out a Mazdaspeed 6 that i recently acquired at auction. My current equipment is in my signature and i know, its a mess. Basically the trunk is set for equipment as the only things i carry for work are a small tool box and customer purchased equipment. I have a cut out of peg board on the back wall of the trunk for my amps. What im shooting for is a box for maximum SPL but also SQ for 2 Skar ZVX-8" (maybe 3, havnt decided if i want to purchase the 3rd one yet). 


ANYWAY I am good with woodworking and have all of the required tools so im looking to see if anyone out there can make me plans for the perfect box blueprint/plans for my application. I am willing to pay via Paypal, Cash app or other available option. Please let me know if this is against the rules, if it is i apologize in advanmce.
