Can you tell me what all of these mean? I know qes has to do with what boxes work and such but that is it. Anyone wanna give me a basic run down and how to understand these specs?

I googled and found this:

Car Audio: Thiele-Small Parameters

Didnt read through it yet, but it still seems technical...

EDIT: Also found this: T/S Parameters explained - SSA Car Audio Forum

What I don't understand though still is telling how a sub will like a bandpass enclosure. Is this when the qes would be around .4 since it's in the middle of a vented and sealed or whAt?

Meaning .4 for a 4th order since it's sealed/ported

An EBP of 100 or more suggests using a ported enclosure (and 6th order BP). An EBP of 50 or less suggests sealed or 4th order. EBP between 50 and 100 suggests either type of box, and either type of BP.

EBP = 1/Qes * Fs

EBP = 1/Qes * Fs
