Well i was looking at possibilities for subs for my reg cab and was wondering if somehow i could manage to squeeze a 15 sealed w/ 2 cubes behind the seats. After checking out a few spec sheets and some calculations and measurements I think it could fit. Basically i have heard that lower freuquency waves from larger subs are not fully completed inside smaller cab trucks, and i would like to hear any thaughts or inputs. Im not really too concerned with the whole larger cone worse sound "theory". Or would it be better to go with a slightly nicer 12 and port it.

15 choices= ss rl-p, Re SE w/ XXX voice coil
12 choices= RE SE, rl-p, id max, Re SX

 

Awsome choises there man

But honestley, do you have enough backspacing. Some of those subs are deep and I wouldnt thing you would be able to fit them without taking up alot of leg room, unless your pretty short and like to drive with your seatback about straight up and down

Ive never heard the idea of larger subs not being able to complete lower frequencies.
I would call BS on that one though.

I would go with a 12" Rl-p and port it if there is enought room for a box that big. Think, youd be the first one on f150online with Soundsplinter

 

I don't think that it's impossible, but it'd most likely be highly uncomfortable. The only way I could see one fitting is if you had it centered to where the speaker was in between the seats... but if you did that then you'd more than likely lose the functionability of your arm rest. (I'm not sure you would be able to move it up and down.) If you had the time and money (And the nerve) you could always go for a blow through, but that's more on the extreme side. But, as the saying goes... if there's a will, there's a way.

 

I think i measured right, and if i take out the back plastic molding that will give another inch, i think. My seat is far up , and im only about 6 feet. The bottom of the box on the drivers side would have to be where the sub is mounted and the bottm = 14 inches and top = 6 inches and looks like the height will be around 20 inches and length around 50 to 55 inches, all measurements minus the 3/4 mdf board. The front face where the sub would go is gonna be about 2 feet long and the width of the seat. Now i just have to look more closely at all of the specs of the subs.

And what i think i meant to say was larger subs create longer sound waves that arent fully completed inside smaller cab trucks, but still i think its just a theory.

And the 12 rl-p also sounds good, so i dont know, thanks for the input.

 

Well if you think you can do it, go for it.

Now that theory-Even a small sub can create a longer sound wave. A sound wave is a frequency, and freq. is measured in Hz, and even small subs can play low frequencies.
