how do i test if my speakers are dead of if it's my tuner?

The DRA-295 is actually a receiver, not just a tuner.

There are two speaker buttons on the front, Speaker A and Speaker B. Make sure those buttons are selected, specifically speaker A. It is possible someone accidently push them off. Also check in back to make sure the speaker wires are connected.

If the speaker selector is on and still no sound, try plugging in a pair of headphones. If no sound then perhaps the receiver is broken. Maybe you can hook up a CD player and try that also.

You can test the speakers and the connection to the speakers by touching the speaker wire leads across a 9V battery for each channel. At the very least this will isolate the problem between the receiver or the connection/speakers.

This may not necessarily help since usually the receiver has separate amps for the headphones and for the speakers. One can be fuxored while the other still working.
