I've recently bought this little 2*3W USB-powered amp and it is working pretty well with my old Panasonic boombox speakers (rated 2.7 ohms, 15w peak input).
However when switching off the USB power i hear a "pop" noise from the speakers.
I've seen there are pop-suppression circuits to avoid that, but i'd like to go with a passive solution not requiring any extra power.
So can i just wire 2 slide switches like these in series with the speakers and manually flip them before turning off the amp?
Are the switches better wired on the positive or negative side of the speakers?
