I absoulutly hate sony Xplode, I would never buy one, EVER. But i bought a second hand car with a Sony cdx-c6800x deck in it. it was working fine at this stage, a few days later i got around to taking the sony one out and puting in my good kenwood i had. I then put the sony cdx-c6800x in my other 4wd car, when the time came to test it there was no sound. I then took it out thinking i stuffed up the wiring but everything was good. It plays cd and and you can select a channel fine but you can hear a thing. The wiring is fine and i tested several other speakers on it but to no avail. Sound still comes out the av Leads at the back, But nothing out the 4 Channels. ???????? Has this happened to anyone else, can anyone help, I cant afford to buy another deck right now? Thanks in advance Chris, Australia
