Need to build a better box. Let me know if anyone have built one before. I have a space of 36x20x24. Will be behind seat of a s10 extended cab. With sub facing up. Recently bought a Soundstream Rubicon 2500 rms amp to push it. Sub is still new and will be push at 4 ohms during breaking in period. Powered by a yellowtop battery. Will try to get a HO alternator soon. LMK Thanks in advance.

They like big boxes with a low tuning since they're a bit bigger than a normal 15" subwoofer. 4.5ft^3 with a 30-32hz tuning will work well for most people.
