Those would work fine. On the little stereo I just did I have 25 watts going to 2 coaxials paired with the tang band sub at 50 watts and I had to turn the gain down on the speakers. My speakers are crossed over at 150 HZ HPF though, which lets them play much louder than if I had them playing down to 80 HZ.These are the lil speakers lol 14w x 14w built in.
