Had it hooked up to 2 Yamaha 80w outdoor speakers. Sounded ok for about an hour until it crapped out. Probably was just a defective unit but I returned it and got a Sabaj A3. For the extra $40 Canadian you get 80w x2 instead of 50w. A remote and a nicer looking and sturdier feeling unit that sounds better. Well worth the extra money imo
