2001 Dodge Grand Caravan Sport. Van has factory installed AM/FM Radio/Cassette Player with separate CD player Radio clock works, but no sound from radio, so it's getting power. I installed 3 radios from 2001 Dodge vans, but none would produce any sound. I don't know if there is a separate amplifier Any ideas?

 

If you have premium sound system, the speakers are powered by a relay. Check the fuse to make sure it isn't blown

 

I looked in the box in the engine compartment, but didn't see anything about speakers. Can you give me a little help with locating the relay.
Thanks. Chuckroast

 

The one that says "name brand speaker relay"

 

Thanks so much for your help. The schematic on the inside of the box cover has "NBS" rather than Name Brand Speaker and I just overlooked it. thanks again. I haven't had a radio for 18 months. Chuckroast
