alright thanks like i was thinking about running 2 t2500.1tbcd one to each voice coil. but would that be to much power?

i think the n3 has more control making it have a "better" sound than the sp4 at very high volumes

also notice the difference here:

sp418: Spl: 87.8dB 1W/1m | 87.9dB 1W/1m

n318: Spl: 95.3dB 1W/1m | 95.4dB 1W/1m

The efficiency rating means nothing, just FYI. It is carried out at 1khz, which isn't relevant to subs

They dont need that much to get loud. I would run one 3500 to a single one in a daily setup.

4.5 cubes is not a lot of space. I would try and run two or three 12's

that leaves the sp4 out of the question. they dont make sp4 in 12's

if you are dead stuck on FI. get 3 12's Btl n2

if not you can get DC XL, aa mayhem they are good subs and for sure can take more than rated power
