A JL 10W6 has two 4-ohm voice colis, so each woofer can be wired for 2 ohms or for 8 ohms. Where do you get 6?

Can I use only one channel from the amp at 2ohm and leave the other channel free?

Why would you want to do that? If you connect the speaker @ 2ohms to only one channel, you get 400 watts. If you connect the speaker @ 8-ohms to both channels bridged, you get 400 watts. Only in the higher-impedance bridged mode the amplifier will run 4 times cooler, much quieter and with far less noise or chance for distortion. A better solution all around. Just make sure you set your gain properly for the 8-ohm net load.

Its true I mixed up the JL ohms.....Illl just bridge it and run the JL at 8ohms.....when you mean watch out for the gain at 8ohms can you be more specific?

It's 8 or 2 per woofer.

Your amplifier input gain control must be set up to match the output from your HU and to deliver it's power into the load being presented. Your amplifier produces 400 watts into 8 ohms, which corresponds to about 56 volts output. Do a search for setting gain or refer here if you don't know how to do this.
