So to start off here I've built sealed boxes in the past for my vehicles without issue(matter of fact the last box I built for my Silverado that was sealed with 2 JL Audio 10w3v3's I still get complements on....miss that truck), but it's been a LONG while since I built a "truck box" or "regular cab" style of box since my last Toyota single cab I was lucky enough to score a set of diamond audio 10's in custom built boxes for free. Where I'm hitting a wall on the current build is that I'm intending to run a single RF T1D210 along with a pair of RF P2D28's, the idea is an 8" behind each seat with the 10" in the middle of the 2 seats(no center console currently and don't really intend on putting one in) and I can't find any info relating to anyone building a similar setup to at least give me something to kind of aim at, it's always 3 of the same subs if I do come across a triple sub truck box. Now where I get extra confused is do I make the box in manner where it's 3 separate chambers so that I can seal the 10 and port the 8's or seal the 8's and port the 10? Or do I make it a single chamber and seal all three or port all 3? I listen to predominately hip hop, southern rap, some country, minimal metal-ish type rock, but majority is hip hop so obviously bass heavy music. The 10 calls for 0.75 cu. ft. sealed and 1.5 cu. ft. ported with a mounting depth of 6.375", the 8's call for 0.23 cu. ft. sealed and 0.65 cu. ft. vented with a mounting depth of 4.76". The amount of cabin space that I have is around 53.75" width X 20" height X 9.75" depth. Any thoughts/advice/ideas would be greatly appreciated. Yes I know I'm really pushing it as far as speakers to available space, but I'm kinda stuck with what I've got since I rather screwed the pooch 6-7 months back when I purchased everything... I thought I was gonna have a bit more room in the cab after I installed the custom one off bucket seats that I had made, after the cost of the seats I was being a baby an didn't want to spend the extra $100 or so on the RF T1D210-S so I got the RF T1D210 instead, and that's biting me in the *** currently because the shallow model would've made this 100 times easier but since it's been so long since I purchased everything I don't feel like fighting with the ordeal it would be to return it(not to mention how it is with covid everything is constantly in stock then out of stock then in stock briefly only to be back out of stock). So yea as said above any help would be GREATLY appreciated cause I have to get this box built asap as my buddy who's storing my materials/tools to build it with dad is going to be returning soon from a long vacation and he's way beyond ridiculously about anything being in his garage etc(which I do understand to a degree being as I was when I had a garage but I was nothing like my buddy's dad)
