13.8v switch-mode power supply

I have a 2011 XFR.
If I want to have the audio blasting in the garage is it ok to attach a 13.8v 20amp switch-mode power supply to the battery (as in +post and -chassis)
Reason I ask is that when I attach my 16amp charger the battery warning will appear after awhile and the system will shut down.
Is it ok to have a power supply rather than a charger hooked up for short term use. I see guys at car shows with power supplies hooked up with there audio systems running all day.
