Um, not really. You'll be hard-pressed to find ANY sub in which 1.5 cubes is "too big". For most 12"s, 1.5 cubes is on the lower tolerable end. Th
ose MB Quarts in particular are optimal at over 4 cubes EACH. That's over 8 cubes for the box.
You best match for that box are these:
RE Audio SRX12 12" Dual 4 ohm Car Subwoofer their optimal enclosure is 2 cubes each (4 total) and that's about as close as you're going to get. 32 Hz is kind of high of those though, so expect a bump (car transfer fn will exacerbate this further), unless you EQ it down. If somebody finds a better match for that box spec-wise for under $100 each, I will buy them for you. (Disclaimer: previous statement not legally binding)
