: Ensure that if you hook up two external passive speakers simultaneously, they are both rated at 8 Ohms . When wired in parallel via the dual output jacks, two 8-Ohm speakers create a safe 4-Ohm total load for the amplifier. Do not connect two 4-Ohm speakers, as this drops total impedance to 2 Ohms and can permanently damage the power supply. 5. Troubleshooting Guide for Better Audio Performance Problem: No sound output.
