You will need a speaker and something to plug into the input to test but yes, you can use it for everyday use. Just remember the sound will be mono, even with a stereo device hooked to the input. Make sure you hook the speaker to the right terminals. For example, if the speaker is 8 ohms impedance then hook it to the com and 8 ohm terminals. You can use more than one speaker if you wish (sound will still be mono) by wiring them in series - again, just make sure you hook them to the right terminals. For instance, if you wire two 8 ohm speakers in series the total impedance would be 16 ohms so hook them to the com and 16 ohm terminals. Also, make sure the speaker(s) you use are rated for the wattage the amp puts out.
