question from cav2006

Need an audio expert for this one! Just purchased a 95 Trooper, runs great, but no audio! It has a Pyle PLVIN70 in-dash monitor, Clarion VS715 dvd player and a Virtual Reality Sound Labs VR3 200 watt, 2 ch amp installed. No head unit at all....How do you recieve get or adjust volume with such a setup? All the units have power(time, date on front of monitor doesn't light, but screen does) But absolutely no sound ! Your help would be appreciated!

the in-dash monitor may be a touch screen, or the setup is controlled thru the DVD player

i assume it has speakers? nothing was said about that. it's probably controlled by the dvd player. are there rcas running from the dvd player to the amp?
