Has anyone done a dual 12" sub box under the seat of a 2004 f150 extended cab. I heard it can be done... I just wanted to know if there is someone that has done it, or knows where i can get a pre-made box .???? Thanks for your suggestions

 

a few of us have done it but more that likely you'll need to install a seat lift and build your own custom box.

 

i think supercrewsound.com has one? not positive though

 

I would like to do this as well. They only have dual 10's and single 12's on ebay. And I cound'nt find anything on crutchfield either.

 

o nvm jsut looked supercrewsound only has boxes for 2 10s sorry

 

I have the dual 10 box in there now.. I just want more bass.. And deeper hits too... Just cant get that out of the 10s....

 

I beg to differ. What is the ohm load you are sending to the amp. What is the brand of the amp and subs. Have you tuned the amp? What is the volume of your box?

 

Not to drag up an old post, but if you find an Audio Enhancers Enclosure dealer, they can order you an under seat dual 12" enclosure for the 2004 F-150 Extended Cab. It is an SSC120, and when they order they can specify cut for 12", but there is an upcharge.

 

Very few 12" subs can work well in the airspace available under the seats without a seat lift. Just because the subs and box fit doesn't necessarily mean that its going to perform well.

Generally, swapping out 12s for 10s in the same airspace will yield worse results - "boomier" bass and worse frequency response.

 

Very few, but there are several that can and do work in the airspace that is offered in the enclosure I mentioned. Usually slim such as the Rockford P3S, or even the Phoenix Gold SL series. Just check to make sure the subs choosen will work with the enclosure, and since it is sealed, you do have some play room seeing as sealed enclosure specs are pretty forgiving.

 

The F3 for either in .6 ft^3 is ~66-67hz. Qtc for the RF is 1.02 and for the PG its 1.292.

It can work... With cabin gain you may be able to get decent response. I prefer both a lower qtc and F3.

 

i just put my 2 12s on top of my back seat. but then again my 2 12s need 8 cubic feet of air.

 

have u tried the jl w3v3 4ohms
