Would it help or hurt spl levels if you sealed the the two vents that are in your trunk, the ones that vent under the rear quarter panels. I have two solobaric 15"s in two 3.5 cubic foot boxes and while they are playing you can hear tons air escaping. I need to know cause Im about to dynamat my trunk and need to know if i should seal it or not. Would it make a significant differance if they are sealed or not.

Yeah, I'd seal 'em. Especially since you can hear the air movin in and out!  I don't think you'll get a huge gain, but it'll certainly help out.

If you plan on attending a DB drag race, then sealing them would be a good idea. Your ears will not notice the 0.1db you may or may not gain from it. But if air is escaping, you would be losing pressure (SPL)

Question? Would spray-in bedliner work as well as, or be used in place of Dynamat. I am thinking it would kinda work the same, but I am interested in knowing. I have access to a bunch of it...

The intention of dynamat is to lower the resonant freq of the body panels by adding weight. Using spray in bedliner should accomplish the same goal. Not sure if it would be more or less effective though.
