A:Answer I have been running 4, 4 ohm speakers, it's not good for the unit, it will run warm, I put 2 desk fans blowing through it, it increases the power when you drop the ohms, but much lower than 4 might not be wise, I only knew this because I spent 20+ years designing car audio, just remember to KEEP IT COOL and dust free. HEHE my car amps run at 2 ohms, my sub amp at .5 to1.
