This is my first serious project. It's a LM3886 from chipamp.com. I got my inspiration from all the guys on this great forum!
Case is aircraft aluminum as well as the transformer cover. Isolating feet were machined from copper/bronze alloy. I machined the heatsink from solid copper billet. Red oak with a cherry stain dresses the sides. I cut the volume knob from acrylic and the bead blasted for a frosted look.
The transformer is a 300va 25 volt dual secondarys. Right now I am building some full range speakers to pair it with. I need to tidy up the wires still but overall I am happy with it.
I was wondering, if I wanted to put a subwoofer out for a powered sub what would be the best way to do this. I've searched but having trouble finding clear suggestions.

Thanks for the compliments. Very surprised on the quality of sound and the power out of such a small number of components.
I'll give that sub-out circuit a try.
If anyone is interested I can machine some costume isolating feet/spikes for your amp/speakers. I would gladly give out a few sets for all the knowledge I have gained from you guys!
