Two cheap 12s or one really nice 12?

 

I'm looking for really loud, deep bass.

 

The cheap subwoofers would be the Kenwood KFC-3012s (400w rms each)

I had a pair of them in my sealed box and it sounded great! The single 3012 in the ported box is almost as loud, but I blew one of them //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

 

The nice one might be a RE Audio ***-12D4 (600w DVC woofer)

or a Kicker CVX124 (750w DVC woofer)

or a Soundstream T5-12 (900w DVC woofer)

or anything that anyone else might suggest =]

depends on power, space and how cheap/good the subs will be. among other things.
be more specific

Not very much space at all. I have a small car with a small trunk..

I will be pushing them with the amp in my signature.

900w @ 2 ohms, 500w @ 4 ohms

then u dont wanna go cheap.....

get a good 12 and u mite get loud and low, depending on what u get

2 12's will generally be louder because you double the cone area and that adds ~3db IIRC. if you double the power, i think thats another 3db (not sure though, im also still a noob)

as for lower, its all in the box really. id suggest maybe fi q or shiva x2
