haha. x2 on the demo board comment.

that being said, demo boards are difficult to set up right.. but its possible.

im not sure what you mean by 2 ohm "cheaters" though... the low end diecis are all 4 ohm speakers.. they do have a very high sensitivity, but thats more because they are meant to be drop in replacments for non-amped systems. we currently have 4 sets in the front doors of a jeep patriot off an ep-4, and the thing JAMS. wish the tweeters were a little brighter, but... they are cheap speakers. cant have it all. haha
