Subwoofer Amplifier Schematic
I'm looking for a schematic for a subwoofer amplifier that has stereo line-level and speaker level inputs, sums the low frequencies of the channels, and has an adjustable crossover. Anyone know of any good examples?

Kudos on the subwoofer amplifier part, but as far as I can tell this doesn't cover the line-level and speaker level inputs with an adjustable crossover, the part I'm interested in.

Sub amp schematics
This amp based on two LM3886 chips is very simple and has what you are looking for. Check toward the bottom of the page for the schematics:
