Using a pre-packaged BTL amp, rather than this circuit?
I just ran across this thread on vwvortex:
Assuming the posted knows his stuff (I'm not in a position to tell), it looks like the monsoon amp expects a BTL load swinging around 6V on all inputs 4 inputs. Also, there's this talk of BTL a single input being out of phase on + and -. Do the diagrams here or in R32 JUhl's post do this? Clearly they work people have heard pretty good sound coming out out their speakers, but are they correct?
I'm wondering if we can find a pre-packages part that converts either speaker level or line level output from a soundcard into this BTL signal. Somthing like this:
The little bit of searching I did didn't turn up any pre-packaged car audio amps that had BTL output
