Featured Need help finding a sub to match my SPL GRLA 1250 amp

I currently have a Pioneer DEH-X6500BT replacing my old OEM radio inside my 2004 Acura MDX and came into possession of a SPL Gorilla 2-channel 1250 max watt Amp that has an RMS rating of 220 watts at 4 ohms x 2 channel, 280 watts at 2 ohms x 2 channel, and 560 watts x 1 channel when bridged (2-ohm minimum impendence unbridged and 4-ohm minimum impendence bridged). The amp requires 4-gauge wiring (as stated on the manufacturer website) so I purchased a kit amp kit on amazon that comes with an in-line fuse holder, the wiring that was originally wired in but never connected to the battery was 8-guage. My question is what subwoofers, or subwoofer should I buy to match the RMS output of the amp? I’d also like to add that I do want to try bridging the amp to get the most out of it since its capable without blowing my OEM speakers since I want to swap them out to match the sub and amp.

The amp in question

I set the everything like the crossover and Bass EQ at half to be extra safe for when its connected fully

This is the wiring kit I bought; I still have pictures of the original if needed

You need to decide how much room you want give up for your subwoofer box. We can give you good advice about subwoofers, but if they will not fit in your car ….
 
How many subs do you want, what car is it going in, and how much are you willing to spend?
I'd like to have a dual subwoofer system going into a 2004 Acura MDX, in the back cargo area where I have the Amp. I'm willing to spend up to 300$ for a goods sub setup so I don't overwork my Amp too much.

This is where I'd like to have the sub setup
