I bought a 2004 Chevy Venture that did not have a radio in it. I thought it would be easy to install a After Market radio in it. Power and all functions work except there is no audio output. I ohmed out all the speaker wires thinking there was a ground issue. They all checked out. I then hooked a tone generator to each speaker wires to make sure they weren't blown. Checked out good. Any help would be appreciated.

are all the speakers the same ohm rating? if they are not, the aftermarket radio will think a short is present. disconnect either both front or both rear speakers and see if you get sound.


does the factory system have an amp?

Yes. I checked. They all read the same.Not sure on power amp.Can't find any info on it.I thought maybe that was the problem and went looking for a fuse. No luck.

Found the problem. After moving some wires around,I found another Blue wire in the bundle.Ohmed out the same as the rest, nevertheless I decided to try it. Violia. It worked. Thanks for the tip.
