do you all think this would this be a 'hard' thing to build? About how much cost in components, ballpark? what about time (for a novice, although I am somewhat comfortable with a soldering iron)?

an easier solution would be to find two units, (maybe)

has anyone used a DH500 in bridged mode for sub bass amplification?

here is a handy dandy schematic for future users....

Perhaps find an unmolested kit, or an already bridgeable DH-500 if that is your preference.

One mistake here and you could easily put out an eye and/or smoke the DH-500.

You'd have to locate/price the parts, custom etch a circuit board from a pdf (possible
scale issues), drill the board (before etching helps) with specifically sized tiny bits,
be -very- comfortable with a soldering iron and techniques for heat-sensitive electronic
components, check the transistors (maybe bother to match them), build it, somehow test
it, then install it and test the amp... & probably a few steps I forgot.

All very doable, but not trivial. Then again, potentially fun and rewarding :D
(so don't let me stop you).
