im getting a 2004 f-150 supercab and im wondering about putting in my 2 12's kicker comp subs and i was wanting to know if its possable to do that or not or if i should sell these and get 10
's cause i love bass and all and im looking into putting in my pioneer headunit into it or should i stick with the stock unit for now

 

depends, are you wanting to put them behind the seat or underneath the seat? How much external volume do you have and power? I wouldn't use the stock HU to power them..

 

now i have a little more info i now own a 2004 f-150 supercab im thinking about putting them under the second row i have a amplifier to run them i have a kenwood kac729 amp to run them it runs fine in my car now i have my truck so i was wondering if i can fit them under the rear seat or if i should get 2-4 10's instead cause of the mounting depth and all should i sell the 12's and get some 10's thanks for the info.

Owner of a new 2004 silver f-150 supercab working on getting running boards and sprayed in bedliner soon any info on turn signal bulbs so i can run clear i would appreciate it and also what headlight numbers are.

 

forget the mounting depth, I don't think you'll be able to fit a 12" in there (front to back space) once it's in an enclosure.
There's no way you can get 4 10's under the seat and have the required volume to run them... unless you jack the seat up with a lift kit.

 

Well, I have in my regular cab a ported L78". I actually work for Kicker, and can use about anything space previded. And I tell you, with 400 watts, it sounds flat amazing. Something to think about, possibly ported VR8's, or L58" or even an L78".
