Ascendant Audio

It's a bit small, but in your car it might be ok.

If the box you want to use in your car needs to be small, add some aperiodic ports. Parts Express sells a good one- it's called the Scan Speak Flow Resistance Vent, and they cost about $8.31 EA, $7.89 EA if you buy four or more. Here is the 'blurb' on it from the PE website:
The Scan Speak Vent is an air flow resistant, "aperiodic" damping device very useful in sealed box applications. It works by reducing the maximum impedance at the box resonance by at least 50%. This results in clearer, better defined bass, with more amplifier power and control into the lower frequencies. It also allows the use of a driver in a smaller than optimum sealed enclosure. The vent should be mounted to the cabinet back wall in a 4-5/16" (110mm) diameter hole. About 60% of the cabinet volume should be filled with damping material, being careful to leave an open path from woofer rear to the vent device. For enclosure volumes up to 1.75 cu. ft., one vent is required. Up to 2.75 cu. ft., two are needed, and for volumes of more than 2.75 cu. ft., three vents are required.

Yeah ^ that was my bad. Im pretty new to online forums - and the only other one I am a member of is at 7thgencivic.com and when someone asks for help with audio...its car audio. So that was my bad for not mentioning it before.

Right now I have the sub in a generic sealed Q Logic box w/measurements 10x10x15, is that too small?

Too small for IB?, yes no chance of IB with any driver I could recommend. Car audio is all about cabin gain and mid bass, Home Audio is more about low end extension so the drivers compliance and Fs are usually much different. I can’t really help on car audio, just not my thing.
