He is more of an SPL guy which is why there are 4 per door and 2 tweeters per A pillar. plus 4 18s in the "trunk".

I know we could wire them series parallel to achieve a 4 ohm load and run it that way but he wants all the power he can get. So, 250 watts (MB Quart Onyx 4125 ) per channel at 2 ohms and 125 for tweeters at 4 ohm is what he's looking for.

The resistors would have to be 4 ohm, 50 watt resistors then correct? the gain won't be cranked full obviously because it starts clipping around 3/4 of the way.

Thanks for any help.
