All good, but I wanna hear it louder!

After testing the SD-Card object and worked very good the first time, I compiled this MIDI player by Andy Schenk ("Ariba" in the Propeller Forums). And I have loaded the "NUTRAC.MID" [MIDI format 0 only!] into the SD-Card as a test.
I have changed some of the code to print the messages onto the UART instead of the TV screen. Pins 0 and 1 are to the speaker, and what he had recommended was this configuration:
Unfortunately, the sound was barely audible. I stuck that 4ohm speaker to my ear (hopefully it didn't scream and break my eardrums!) and I could hear that tiny sound. Obviously, this needs amplification - I'm gonna figure out how to do this effectively!
