that is an awesome driver! go with the wiring config that best suit's your amp at full power! you can alway's change it also, just by the new coil

Stll need to buy an amp for the sub. So should I go for the 2 or 4 Ohm?

It won't matter if it is 2 or 4Ohms as far as how they sound. Just get the config that is best for the amp you are going to use with it.

Wanted to buy the jl 1000/1

it's Rated Power: 1000 W RMS @ 1.5 ohm - 4 ohm (11V-14.5V)

So 2 or 4 Ohm wo'nt make a difference.

Which sub should I take?

Thnx

4 ohm. The amp will run more efficiently, while maintaining same power output.
