Look at the LM4780 kit from Audiosector. The chip is 2 LM3886 which makes it easy for parallel operation for sub duty (have a look at the Schematic PDF).
You can order the extra diodes if you want to use the 2nd amp kit and power supply PCB for another mono or stereo amp.

Yeah, a LM4780 kit is the way to go for a mono block---120 watts into 8 Ω (bridged) or 4 Ω (parallel); either for $32 from Tech DIY Company Store. Even after adding a transformer (AS-3225 - 300VA 25V Transformer - AnTek Products Corp) for $41, a bridge rectifier and two 10,000 uF caps, the cost is still VERY low for 120 watts!!
