why would you want to do that? just curious, a super loud mono channel with a bunch of drivers will sound like absolute ****. your only real options are 1 or 4 ohm final load and from what i seen on a taramps 3500 on ebay is that it does its rated at a 2 ohm load so your going to be out of half the power of the amp or running a load its not rated for.
well it might do 1 ohm not sure the only sites i see selling a "3500" are spanish so im not sure but i think they made a 1 ohm and a 2ohm version.
you must understand that super loud mid and high frequencies will destroy your hearing a zillion times more than a loud low frequency. if your not familiar with tinnitus, but imagine a single high frequency tone that plays in your head 24x7 untill you go crazy and want to put your head in a garbage disposal
