On my 1995 Range Rover 4.0 SE the factory Clarion radio will only play sound out of the passenger side speakers (5 of the 11 working) No sub or anything on driver's side. Radio was recently reconditioned, with new code, etc. All radio functions work perfectly (LCD screen, vol, presets, tuners, tape, CD Changer, etc, plus steering wheel controls) There is power to the amps in the doors. How can I test the amps and the out put on the back of the radio? Anyone know what it should be in voltage or ohms? Anyone want to test their own? Also, by the way-all of the amps are small. Why are these so small when the ones in my Classic are large? The sound output I think is about the same, 120Watts. Classic radio (factory) sounds great.
