350 at 1 or 4 ohms would be good for general listening, but if you want a good kicking then go for anything up to 650 - it'll make the JL sing. Just be careful with the gains - don't send the amp into clipping
Personally I'd go for a DLS A6. 500w rms @ 4 ohm, beautiful looking, and Class A/B to boot

I have two myself, wouldn't change em for the world
