I have a Canton Audio AS 650.2 SC subwoofer with a failed preamp circuit and I'm looking for replacement options, since the company is not being responsive, and it's doubtful they would offer a replacement preamp circuit. I need speaker level inputs, crossover, level control, phase control, and auto on. I guess I'll have to figure out how to splice the new preamp into the harness for the ASC200 amp module, and would also have to modify the aluminum backing panel to handle a different switch and jack configuration. Major pain in the rear, but I don't want to send this nice sub to the garbage heap. Does anyone know of preamp kits available that would suit my needs? Thanks, and sorry if this has already been covered.
