fastfox89 Posted November 18, 2008 Author Report Share Posted November 18, 2008 dude, i can't say that 145 is for sure gonna happen, but I only have 2 15's in sealed enclosures in the trunk of a sunfire and i do 145's. so, it is very possible, depends what you want the system for, if your gonna tune the vent to a really low frequency, you might not get there, but there is no telling with no details like your electrical, and a for sure enclosure and all. very possible though. I know of a suv that does 148 on music with 2 15's and he kept his back seat. its not going to be a comp car just something to piss old people off at red lights..lol for electrical gona do a few extra batteries and an alt, 10 cube ported box tuned to 40-45 not sure about that yet that’s something i was hoping to get some advise on from one of the great minds on the site i still have my back seats. but i took out my 3rd row seating (Durangho) i know you jeep doesnt have that so dont gotta worry about it. but if theres something i can help with ill let you know as far as my knowledge allows. (dont ask for design as in how to tune and such...i dont know how to design boxes i just build with plans other people have made for me haha) cant ask for much more than that Quote Link to comment Share on other sites More sharing options...

eliassami5 Posted November 18, 2008 Report Share Posted November 18, 2008 (edited) The only way you are gonna fit 4 15's in the back of a cherokee is if you take the box all the way to the top of the ceiling and make it a little more than a foot deep, that will give you ~10 cubic feet. The jeep measures: from spare tire to the wheel well it measures 3.25', from floor to ceiling it measures 3', and from the top of the back seat to the tailgate you have 2 feet to play with. If you build the box right and you dont tune it too low then you could hit 145's with 4 15's at 250rms each, if your jeep came with the 136 amp alternator then you wont need a bigger one. make the box 39" wide, 36" high, 15" deep with 3/4 mdf and you will net 10.10 cubic feet of space, then that will give you about 9" of space behind the box for your batteries, amp, and whatever else you wanna put there. and yes i also have a cherokee Edited November 18, 2008 by eliassami5 Quote 91' Jeep Cherokee - The Heep Just Empty Every Pocket 96' Volvo 960 - The B◘x [sPL_4_U] HiFonics - Alpine Pioneer - Clarion Infinity - Kicker KnuKonceptz Link to comment Share on other sites More sharing options...

bman8891 Posted November 18, 2008 Report Share Posted November 18, 2008 You should look into other subs if you haven't already bought the mtx's. DD, Fi, and RE make great subs. A friend of mine is doing 150's with only one 15" dd. Just something to think about. Quote Link to comment Share on other sites More sharing options...
