draper Posted April 14, 2012 Report Share Posted April 14, 2012 I got a 99 grand marquis No that is to wide, if you put the box in the well in the trunk its 40.5 inches across, any bigger it wont fit all the way to the bottom In my experience 25 is the max height, 26 will work in some places but it will rub And the biggest deep I've done is 24 deep, But current box is a 4th order 3 sealed 6 ported ish 10 cubes 40.5 wide 25 tall and 21.5 deep 3/4 birch. With a 1"thick plexi front Which ways are the port and subs facing? 97 crown vic kenwood hu big 3 mechman 270 amp alt 1 d3400 2 d3100 hiffonics collosus (bass) Hifonics Zues (mids and highs) 2 15in kicker l7s dynamat extreme sound deadner viper secured Link to comment Share on other sites More sharing options...
SimonSezGoDwnBit Posted April 15, 2012 Author Report Share Posted April 15, 2012 so basically the 4 12s across the back idea will not work? how come i see people with 4 12s across the back in crowns and marquisss all the time? maybe if i build the box INSIDE the trunk maybe exact specs they will fit? or should i say fuck the 4 12s and get 2 15 l5s and do this SHOULD I FACE THE SUBS UP, OR DOWN IF I DECIDE THIS ROUTE?? WHICH WOULD YOU THINK POUNDER HARDER 2 15" L5S OR 2 RE SX 18S? ANY IDEA WHAT ORDER BANDBASS THAT BOX WOULD BE? if i build this box on my own can i just cut a big ass hole out in my rear deck and reinforce it so the opening on the picture is close to the hole i can cut out in the deck minus any major supporting brackets if i run into anything of that sort. will i have to cut the port out to certain dimension so that i get a certain frequesncy?.. or can i just make it as big as i possibly can with all the space that i have and HOPE it sounds good cause i dont wanna dump allllll this money into it and it sound like shit and just sell it all and get some prefeab l7 2 15 box Link to comment Share on other sites More sharing options...
SimonSezGoDwnBit Posted April 15, 2012 Author Report Share Posted April 15, 2012 and draper, to me it really doesnt matter if the box goes on the side steps or not, i rather it do so that i can place amps under it Link to comment Share on other sites More sharing options...
SimonSezGoDwnBit Posted April 15, 2012 Author Report Share Posted April 15, 2012 Idk it would be close. my box is 40x26x18 with sub up port up. You should really build your own box. with 4 12's you don't really have the room for all those dividers and ports.Way to much potential net volume lost. Also if it did actually fit, you would be wasting trunk space because the box would be sitting on the side steps of the trunk... What do u meter? What subs etc? hey no i dont want to set the box inside the tire spot? lmao, i wanna know if it will fit across the trunk ontop of the humps. sadly everybody thinks no :( :( Link to comment Share on other sites More sharing options...

So ur port length will be pretty short probably around 6 to 10" Im trying to find someone who got a 148+ from the trunk SCSB Santa Cruz Speaker Box Build logs: Daily Driver Lemon Marquis 2 american bass 750.1s 350.4 on 14 focal 6.5s sq 945 on 4 hertz tweeters Mystery subs http://www.stevemead...__fromsearch__1 The Mustang 'dubbed' Shirley the project from bullet holes to badass http://www.stevemead...cond-skin-time/ Link to comment Share on other sites More sharing options...
CortezDTV Posted April 15, 2012 Report Share Posted April 15, 2012 Careful cutting that metal out, im welding in a massive amount of steel for support cuz it was flexing over 3 inches.... and that's not good, means it was loosing structural rigidity but I have also cut the armrest support out SCSB Santa Cruz Speaker Box Build logs: Daily Driver Lemon Marquis 2 american bass 750.1s 350.4 on 14 focal 6.5s sq 945 on 4 hertz tweeters Mystery subs http://www.stevemead...__fromsearch__1 The Mustang 'dubbed' Shirley the project from bullet holes to badass http://www.stevemead...cond-skin-time/ Link to comment Share on other sites More sharing options...
