haroldl Posted September 19, 2006 Report Share Posted September 19, 2006 This has happened to me twice. I always remove the faceplate after turning off the engine. When I get into the truck first thing I do is intsall the faceplate then I start the truck. Normally I hear music playing before and after I start the truck, but yesterday no sound came out of the speakers. No matter what I did, checking all fuses options or setting etc. there was no sound coming from the speakers. This lasted the whole trip (1.5 hours). I removed the faceplate as I always do after I got to my destination. When I came back to the truck after about 1 hour installed faceplate started truck I could hear music coming from the speakers. What could cause no sound from spaekers? Is there an option or a setting I need to do? Everything seems to work except no sound. Quote Link to post Share on other sites
cntrylvr79 Posted September 20, 2006 Report Share Posted September 20, 2006 What kind of truck is it and what year? Where is the brain located. Quote Link to post Share on other sites
haroldl Posted September 20, 2006 Author Report Share Posted September 20, 2006 I have a 2000 Ford Excursion and the brain is mounted in the dash under the avic-n3 Quote Link to post Share on other sites
haroldl Posted September 20, 2006 Author Report Share Posted September 20, 2006 I forgot to mention its been installed for 6 months and working perfectly until 2 weeks ago. Quote Link to post Share on other sites
cntrylvr79 Posted September 20, 2006 Report Share Posted September 20, 2006 If it was working properly for that long, I'd lean toward it being a bad speaker in the truck. Basically when one of the speakers starts to go, the amp inside the brain will read the speaker as a short circuit. When that happens, the amp will shut itself down to keep from frying. Try testing the speakers at the radio harness. You should get between 4 and 8 ohms resistance between the positve and negative wires. Also make sure you don't get continuity to ground on any of the speaker wires. Quote Link to post Share on other sites
haroldl Posted September 21, 2006 Author Report Share Posted September 21, 2006 Thanks for the info. I should mention I installed JL audo speakers xr570-cxi about 2 months ago. They have the separate crossover network. I wonder if that could be shorting out? I'll check this out over the weekend. Thanks Quote Link to post Share on other sites
