Sundown SA-12: less powerful than I tought?

LOL it is not because it is rated at 800W @ 2 ohms that I cannot run it at 800W @ 1 ohm! The gain can be set to whatever you like you know... Anyway yeah I set my gain with a DMM to get 800W @ 1 ohm (I tested the box terminals resistance just to be sure and it was really showing ~1,1 ohm with the DMM). My gain was already set with the subwoofer output level (on the headunit) to the maximum (which is +6). But some told me that it would more possibly clip at that level so I consider to reset my gain the subwoofer output level at 0 with a -5 dB test tone (instead of 0 dB) and when I want to show off I will just have to crank the subwoofer output level.

I'm surprised no one caught this...

OP, you have a D2 sub? But claim the sub is getting 800 watts rms which is what the amp is rated to do at 2 ohms. So you cannot be wired to 2 ohms nominal, either 1 ohm or 4 ohms. I wonder if you're wired to 4 ohms nominal.

Also, you're going to want your sub level turned up, you're not getting full 4 volts output like that. How were the gains set?

And I agree with Klown, for a single 12" I'd shoot for like 1-1.5^3

1^3???

My box is port up and subwoofer up (I was suppose to face it back but I did not have enough wire, like 5 inches lol, to connect the amplifier to the box terminals, so I cannot move it either I am really straight on wires). Anyway if it was facing back there would only be a small gap of like 3 inches between the subwoofer and the door so I prefer facing it up. My box, like I said, is a home-made ported one (2 cubic feet tuned at 35 hz, L-slot port).

Kicker's sound louder cause they rattle and distort, Sa's put out good clean sound, your ears are used to hearing garbage. Trust me, Sa's pound

And that is not sealed off, and I know I would gain sealed off because it's louder with trunk open

Can't compare a brand new woofer to anything to till it is broke in, they will get louder as they loosen up.
