15 vs 2 12's
i have a 79 f 150 and i am getting ready to put a system into it. i am on a limited budget of course and i was wondering what would be better. One 15" sub and one amp or 2 12" subs with one amp? i do not have the money to get 2 nice amps and 2 nice 12's and i have heard from a friend that a 15 inch sub which is the same model as his 2 12's sounded better than his. i have seen some reasonably priced 15's and it seems like a good idea to me. i was also wondering what you guys have that is a good combination for a 15" sub and a good amp?

I'd prolly vote for 2 12s
15s can be hard to fit behind a truck seat, they aren't just wider, they're deeper too
also 2 twelves have more cone surface area than one 15, so unless the excursion of the 15 is much greater, the 2 12s move more air, so they'll make more sound.
get a decent mono amp and wire the 12s in paralell for 2 ohms

Ah, my bad, i meant parallel. The ohm depend on the load you're going to be putting on it like two 8 ohm wired in parallel will create a 4 ohm load on the amp, but you're probably going to be having 4 ohm speakers for a 2 ohm load.

id personally go w/ 2 10s or one 12. 2 12s behind the seat of a pick up gets hairy and IMO isnt needed if u buy one good 12.

A single 12 should suffice when it comes to hard hitting bass notes....
Unless you are looking for SPL....
15s require lots of volume behind them and a good amount of power to really
make them perform to their potential..
with that said, go with a single bridgable amp with a built in low pass xover.
A nice JL audio 12" would do nicely......being pushed by a 200 watt Kenwood,
Pioneer, Rockford fosgate, etc...

go with two tens. for all the reason above. plus if the have the space a ported box will do more than two 12 sealed and takes less power to do it. i would look at jl audio tens and a rockford 301s amp. two subs are about 200.00 and the amp about 200.00.

http://www.sounddomain.com/sku/ROC301S for the amp (punch is the low end of the food chain, but ok if your onna budget)
http://www.partsexpress.com/pe/showd...D=166911&DID=7 for the subs. (just as good as the JL if not better, 5 year warranty on Daytons btw.
