Audio help needed

Just purchased 95 Trooper, runs great, but no audio! This vehicle has no head unit! It has a Pyle VIN70 monitor, Clarion VS715 dvd player, and a Virtual Reality Sound Labs VR3 200 watt, 2 channel amp. All these components have power(the time, date display does not light up on the monitor however) but with no volume control...How can I get audio?? Appreciate the help!

did you check the illumination wire to see if it is conected?
mabey the face is blown?
