Keith77 Posted September 16, 2014 Report Posted September 16, 2014 good luck getting four 12s in a 4th order in a trunk.. Let a lone a 6th order.. Thats cool. Im way too old to be upset by shit like that. Your name is winston. Your own parents hated you even before you were born. My penis is bigger than your penis I'm far from loud and my roof/headliner flaps around like Adam's ass on a windy day. I think it depends more on the structure of the vehicle.
zrkie Posted September 16, 2014 Report Posted September 16, 2014 Find out what type of space u got.. If u cannot fit at least 4cf per woofer, forget about doin a 4th order :/ Don't like sharing your knowledge? Welll.. Don't come here and grab others then! - GTFO.
T2bumper Posted September 16, 2014 Author Report Posted September 16, 2014 the subs are small and i have about 9.2 cubes total to work with, if i do a 4th order all the subs need for sealed is 1 cube per so if i do 2 cubes sealed on each side and in the center for the port i will have 5 cubes to split between the 4 subs, its not a whole lot but the subs are small and only need about 1.5 cubes ported its alittle less but its what i have to work with, will i be able to make it work? and i might be able to get another sqft in there when i actually get the final dimensions. what do you guys think? 1 dc level 5 15 t2500-1bd Rockford 10 farad hybrid capacitor 4 rockford pro punch mids 2 pro punch super tweeters Both on pro punch rockford crossovers T400-4 (speaker amp) 30ft sky high 1/0 20 ft rockford 1/0 xs d3400 xs d1200 stock batt under hood 200 sqft fat mat kenwood kvt-516 flip-out and 70ft Sky high 14gauge speaker wire
_paralyzed_ Posted September 17, 2014 Report Posted September 17, 2014 it's better to have a single 12" in a proper (big) box than have 2 12"s in too small of a box. You also need to account for box material and speaker displacement. Just go for 2 in a proper box, it will sound better than 4 squeezed in.
CleanSierra Posted September 17, 2014 Report Posted September 17, 2014 You don't have space for a 4th or 6th order bandpass. Either do a, sealed box or a simple bass reflex(ported box). To do a bandpass 4th, you'd literally need like 18-20 cubes. Even with a 1:1 ratio bandpass you'd need 8-10 cubes. Im not the one you want to try to troll. Just a fyi for you.
SlamminBeats Posted September 17, 2014 Report Posted September 17, 2014 4 12s in any trunk will never be loud fyi. go with 2 12s and sell the other 2 for electrical. youll thank me later.

T2bumper Posted September 17, 2014 Author Report Posted September 17, 2014 thank you for all the input, i will just do a ported or sealed box then with the 4 in the trunk 1 dc level 5 15 t2500-1bd Rockford 10 farad hybrid capacitor 4 rockford pro punch mids 2 pro punch super tweeters Both on pro punch rockford crossovers T400-4 (speaker amp) 30ft sky high 1/0 20 ft rockford 1/0 xs d3400 xs d1200 stock batt under hood 200 sqft fat mat kenwood kvt-516 flip-out and 70ft Sky high 14gauge speaker wire
OrionStang Posted September 17, 2014 Report Posted September 17, 2014 And after all the replies he's still gonna try to do all four, ported or sealed. Fucking hard headed NooBs piss me the fuck off lately. Bet this same motherfucker judges loudness by the amount of trunk rattle. SMD Super Seller My Feedback Thread
