10’s or 8’s ?

[Ron36]

So I’m going to be building a box under seat design and my options are 2 Sundown SD-3 10’s or 4 Skar VD -8’s , both will fit in the same SEALED box and ran off a Skar RP1200.1 , I have the Sundown subs already is it even worth it to think about the 4 Skars or will it pretty much sound the same. In my head 4 subs says louder but there smaller and same power. The Amp can be changed it’s not a big deal it’s what I have laying around.

4 8’s will have more cone area so they should be louder.

3 10s actually have more cone area then 4 8s. It's by about 30 square inch.

Either option installed in the same box size and both wired to the same 1 ohm impedance and being sourced the same power, there will be less than 3 dB difference between them so no compelling reason to upgrade. To the ear if you don't get 5-6 dB gain from an upgrade you are just wasting your time.
