just connected 9 to one side of the amp (bridged)... fckin loud! running 3 in series (x3) and then parallelling the 3 groups to equal 4 ohms. didnt have to connect 9 to the other side, my ears are ringing enough now! gonna use the rest as back ups for now unless i switch amps and configure more or less speakers differently.
they scream like no other, they can almost pass as full-range, but im still going to run 3 or 4 sets of low powered tweeters
