Just dropped off my boat at an authorized dealer of wetsounds and they recommended purchasing the A4300 to run all 6 of my XS-650's however when I got home and looked at the specs i noticed they only put out 45 RMS x 4 @ 4 Ohms or 75 RMS x 4 @ 2 ohms. I guess they plan on running them at 2 ohms. Is this a bad idea.

I personally would get the 6450A. It is a six channel amp.

It's not so much that 2ohms is a bad thing, but keep in mind that that 75W's @ 2ohm's will be split between 2 speakers.

Make sure you are comparing apples to apples. JL rates their amps at 12.5V, whereas the industry standard is 14.4V. The A4300 puts out 110W per channel @ 14.5V to a 2 ohm load. That being said, you are going to be running one pair at 4 ohms, and two pairs at 2 ohms. Not ideal. I would consider picking up the M6450 (or 6450A if you want to save some coin and don't live in a salty or humid region) and keep everything at 4 ohms.
