Depends on the sub.

If you have a 400 watts DVC sub, the Alpine.

If you have a 250 watt sub, the JL.

Jl 250.1 is 250 watts at 1.5,2,3,or 4ohms. Anywhere in there and you get 250watts. Also the JL will give you the power from 11volts to 14.5 volts. The Alpine will give you full power at 2 ohms only and at 14.4 volts. I would say regardless of sub I would go with the JL audio.
