Be careful; you should check the ratings for speakers as they can be damaged if underpowered. And by underpowered, I mean both the output wattage of the channel they’re plugged into, and the impedance rating; if mismatched (for instance, a larger speaker designed to be driven at a low impedance like 4 Ohms, plugged into an amp channel rated for 16 ohms), then the speaker may be underpowered on account of the increased resistance (impedance) on the line. The telltale symptom of this is a speaker that plays semi-loud but sounds severely distorted. You risk permanent damage to the driver units in the speaker when you do this. When in doubt check the reference manuals for both.
