Is 2 sundown xv2 12d4’s a good choice?

Thank you very much for all of the info. I have been trying to figure out the dimensions of the box. I need somthing like 5sqf for the speakers, then the port, but when I do the math, I get crazy numbers. My opening( trunk to back seat) is 14.5 high and 34 wide. I’m not sure if I’m doing something wrong, or what, but the length for the speaker aria is coming out around 30 inches, then I need a port behind that. What size should I make the port if both speakers are sharing it?

5 cubes net with 75 ish sq inches of port area tuned to 32 ish.

Correction, I have 16 high and 35 wide to seal off the opening.(just measured again) should I add bracing inside of the speaker aria? Also is it better to put the port in the center or to one side?

I think I’m starting to grasp the concept. Sorry for all the dumb questions, this is my first time doing an install correctly.

Last question, what is your thoughts on 45’s and a triangle at the back in the center of the vent, back wall?

Router all your square edges in the box. Direct the air to the vent. Just because you can and peace of mind.
