shuld l put two 12 inch subs or just one? and where shuld l put the subs?
i haave a 2001 ford f150 extended cab

you can probably fit them behind your seats if they lean forward as mine do

l have a 1999 f250 extra cab and have two 12`s in a box under the rear foldup seat and the amp under the passangers seat. l think if l did it again I`d go with one real good 12 and have both the amp and sub under the rear seat.

if you can get behind l would.

l suggest getting the kenwood excelon shallow subwoofers. Either that or the JL audio shallows. Meant for trucks, and many boxes are available for these. Put them behind the back seats if possible, or under them. These thump with the right amp, so your truck will be loud.

hit me up and let me know what ur budget is and l will get u the best bang for ur buck. Hit me up.
