information on audiomobile sa1600?

[uncadave]

i'd appreciate any information on audiomobile sa1600, even if it's 'if i remember correctly.....' styled information. i know it's signal-sensing for turn-on, has a crossover, i believe it's 1ohm-stable. it has pico-fuse output protection, 40w/channel, 4ohms (i think).

here's what i don't know: there's a switch on one side next to the level adjusting screw. i forget if it disables the crossover or bridges the low side. i have the line input pigtail but if anybody had a pin-configuration diagram, that would be great (yeah, not likely, i know!).
