Wow, this thread somehow got brought back from the dead!

j57ltr: Those "amps on a chip" have their advantages and disadvantages. The good thing about them is that 90% of the circuit is integrated, so it takes less space, can have better noise rejection, and is simpler. The bad thing about them is that the heavy current stage is also on there, is generally pretty weak, and you might run into thermal issues since it's so compact. However, you could use the chip to replace the differential input, voltage amplification, and pre-output stages, and use outboard transistors for the final stage.

edep345: No, not waterproofed. Although, it wouldn't be all that difficult to do. A little silicone around the various openings of the amp, and a weatherproof speaker would be all that's needed.

swiftneed: You mean like a boat with wheels?
