Four 8" Subs vs 3 12" Subs

[All__Fun]

I have a - DOWN4SOUND JP95 - 1500W RMS 5 CHANNEL AMPLIFIER - Which can do : RMS power, 1ohm for CH5 BASS CH: 1212 W x 1
(From independent testing - Big D WIZ)

My rear cargo area measures:
43L x 22h x 16d = 15,136 = Cubic Inches
15,136 / 1728 = 8.759 Cubic Feet

I am deciding upon doing 4 10's or 3 12's in a sealed box.

I listen to mostly hip-hop but I previously had 2x12's and now I want hear something different
I am debating between:

3x Kicker COMPC12

VS

4x Alpine W10S4


I know that 3x12 has slightly more Cone Area (339 vs 314)

I am having a hard time finding the Motor Strength of both subs (Bi^2 / Re)

Can anyone help me make a decision, and also list your reasoning.

I want to stay < $400 on the subs.

(somebody recently stole my previous subwoofers, and now I just don't feel like spending heavy on new subs)

Damnit I fucked up the title. How can I change it to 4x10's ??

Mods can you delete this thread ??

I would run 4 tens sealed or tuned or two decent 12s in a ported and tuned enclosure

Kicker subs are louder than alpine subs in my experience. Kicker is more spl and alpine is more sq.

Four subs can be wired to your amp's minimum impedance, unless you are running goofy jl impedance.

Yeah I would go with this too, and I would lean more to two 12s and get them closer to 600w RMS each.

With three subs they're wired at 1.33 ohms. If you go off the 1212, (without doing the math) I think you are closer to 900-950watts.
