will this work on 2005 harley softtail?

yes it will just connect it to battery on your bike

I do not ride every day I am worried this will run my battery down

This is what we do very well, unlike other brands, our audio has a superb standby capability. Listen to music while the motorcycle is starting, you don't have to worry about draining the battery at all, as long as the motorcycle engine is running, the stereo will always have power. If the motorcycle does not start and you are listening to the stereo, with a 20A battery capacity, you can play music continuously for 10 hours. If you turn off the stereo without disconnecting the wires, the stereo can standby for 270 days without depleting your motorcycle's battery.

Can you hear it over the motorcycle

Not at high speeds or if your bike is noisy.

Can you sync and use 2 of these speakers together?

No you cannot sync 2 of them together
