    The amplifier in that system is designed for the speakers it came with. It is not designed as a general purpose amplifier that you can connect a different set of speakers too. You can *probably* get away with a smallish set of stereo speakers but without matching the impedance you may cause the amplifier to switch into protection mode if you raise the volume.

    What I'm getting at is this, you might be able to find a compatible set of speakers. Maybe. All in all, I'd rather see you get a new amp and a decent set of speakers. Or, just grab a set of multimedia speakers designed for a computer. For about $100 you can grab a 2.1 set of Logitech's that are THX rated and will rock pretty hard. If you've got a little more money to spend check Klipsch or M-Audio. Stay away from anything that says Bose on the box, it's 'probably not worth the price.

    excuse me for disagreeing with the above post but it's not entirely correct. In fact, it's not all that correct period. The ONLY requirement for that model of amplifier/tuner is that the speakers connected are between 6 ohm and 16 ohm impedance. I verified this on numerous occasions, even using it to test various used car speakers I picked up or gleaned from a junk car.

    Point being, keep within those impedance boundaries, keep it well ventilated and it'll do fine on all functions.

    Check out the speakers at Parts Express. Low price and decent quality. Lots of good reviews on Dayton speakers.
