I have a pioneer deh-p2900mp radio in my car , and it been there since i bought my 99 maxima everything worked great till like a week ago . My radio stopped working driving up my driveway, everything works but theres no sound. the next morning i took the radio out and all the wires were connected i turn the radio on and it works. today same thing happened but it dindt start working after i toook it out. What can couse the radio to work but no sound comming out? tried disconnecting battery and everything . anyone has any idea ?

 

well it may be the harness for the radio, try getting another aftermarket radio harness for the pioneer and see if it works, also the radio and harness are old so it may be radio and/or radio components and also check for the fuses in the fuse box next the the steering wheel, it may be a simple fuse

 

if it would be the fuse woulnt the whole radio work ? i moved the cables around while having the radio on and still nothing.

 

How are both harnesses connected? I remember having my Pioneer DVD player wired up with electrical tape, and it sucked. Speakers kept cutting out constantly. I upgraded to Wire connectors I got a NAPA for 3.00. Works great now.

 

they are connected with the plastic splice in connectors

 

How old is the radio? Could be at the end of its life? I had a pioneer deh-p4300 (i think thats the right model number) that lasted about 4 years and stopped working.

 

You guys make me frowny face First off, check your fuses my friend.. BOSE? no Bose? help us out a tid bit please.. The harness is probably fine.. so long as everything is connected properly. Its highly unlikely the radio harness would die after this long.. Its probably the amplifier... sorry bud your prolly gonna wanna try a new Headunit.. if you have a stock bose or a friend with one try it out first.
