Did the box you built just sit down in the storage area?? You must have cut the bottom out of the storage area. My storage area thereis like 3"-4" deep,at best.

 

JL audio is probably one of the best sub companies out there, without spending thousands. You obviously have not ever heard a JL sub. The w7's will blow most anything else out of the water when it comes to loudness and clarity.

 

I didn't have to cut anything up. The box does sit down in the storage area.Here are some more pics:

I took the plastic part out and it was an open bottom. I used 5/8" MDF, so that's the piece of board sitting there.


The sides I added where 3" tall. After that, I added3 more pieces of the 5/8" board. So overall, I suppose the storage area was about 6-8" deep.

 

JL are really some of the best out. High priced yes, but thier quality is top of the line. Longevity, clear sound, hard hitting. Only other sub that comes to mind for tight space are the Kicker Comp's. They make a nice shallow mount unit rated as high as the regular mount, but from my exp. are lacking in longevity.

 

not just any sub. if were to look at the second web site i likned up will show that theDD1500 sub holds 450rms. put in theright built boxit will hit hard.the amount ofspaceavailable would be best for an 8.it wont distort as soon and the volume is idel for an 8in sub. the 12 to sound proper and reach its optimum proformence would need bigger box. if u were to stick that 12 underone of the rear seats it would have the right volume i belive.

i wouldnt say all that. jl audio is good. but as in sound quality they dont cut it. ur in the wrong direction. image dynamics makes a much better sub for that. or dd is even up there as well. adire( now closed) was a great subwoofer to comepte with. anyone in the industry will tell u that there are many companys that arent huge and make great subs for the price as compared to jl audio. kicker comp is jus trash. sorry but my cousin had 2 L712s and i would way harder that his 2 subs being pushed at 2000watts with my 1 image dynamic 12 at 2000watts.
there is so much like rms, excursions( how much the sub comes out), efficiency( how much power to produce how much decibles) , magnet size, material ( not all materialis great for one thing) and price.

 

true sealed boxes are idel for sharp clean bass...like for rock, classical, pop,
ported are used for when the 1. the box is to small and u need to compensate for volume 2. to compete 3.rap r&b .

 

As far as sheer power handling JL arent top of the line, but IMO a great sub for a decent price. I love the old ID, Diamond Audio, Pheonix Gold, but they are few and far between. Alpine makes good things but more and more companys are totally commercialized and are sold by people at best buy who know nothing of good sound

Heck, my duel 2ways sounded better then the store owners JL audio setup that would have cost about 800 bucks installed

 

You can only do a 10" under the back seat unless you build a single enclosure and go far to one side to make up air space (I speak from experience). A ported box also is usually bigger than a sealed box.
