6 12's vs 4 15's

[bamaman]

It's almost rebuild time for me and was thinking 6 yard sale sa 12's or 4 fu audio 750v2 15's. They will be flat wall in an 04 f150 extended cab on a banda 5k till I can save up for more power. Any thoughts or opinions to go one way or the other?

1 fu should be louder than 1 sa same size (based on models i've been doing) but that comparo is about same cone area so unless 2 extra motors help i'd say 4 fu's but really that depends on airspace and box.. also i posted yesterday on my box thread that i noticed the fu 12 tends to play louder below 40hz and drop off really fast after 45 hz and that was with a 35hz tune.. see what jeff and popwar say..

Assuming that amp makes close to rated power 4 2.5" coils are not going to like it very much so you might lean towards the 6 subs for the extra thermal power handling.

BS. I have had many friends run 4 SA 12s on 7k amps daily at 1ohm and all have been fine. I'm sure the FU woofer will be fine on a 5k. But I still say go sundown //content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif

4 FU 15s would be fine on the 5k. 4 15s will be slightly more cone area but 6 12s will be more motor force. I think the 6 12s would want more power though.. Its a toss up. For an F150 wall I personally would do 8 12s.

motor force doesn't add up. all 6 12s has is more coil cooling and more expensive.

phase and loading is more important that arguing cooling or motor force. lol

My buddy who knows what he is doing runs double rated power amp to his subs = the subs can handle double rated power for a guy I don't know who's build I haven't seen who has to come here and ask advice.
