try hooking the radio power wires to the battery! To '' TEST'' twist red and yellow put on the poss. blk. on neg. ! take a speaker and test speaker wire out put! if don't work output is blown out! but will still work with rca jacks hook to small amp ! this to pull sound out of your radio for sure!!
So everything is coming on but you have no sound from anything?If that is the case you may want to check the amp fuse.The car has a factory amp i'm trying to remember i think it is in the trunk.Look in your owners manuel for the fuse box location.If the fuse is good then the factory amp may be bad.Or you may have a blown speaker that is showing a short and putting the amp into protect.If the amp and or speakers are bad i highly recommend just buying after market speakers/amp.The price for the factory equipment is very high and there labor rates even higher lol.Plus if properly installed you will noticed better sound from the after market stuff as long as you get brand name equipment.Go to a well trusted audio shop in your area they should be able to see if it is a speaker or amp problem if your fuses are all good.They should be able to test the impedance of the speakers at the amp for you and see what is going on.
When you have no sound on the radio the first thing to checkl is the speakers. Using the smallest voltage battery you can get hold of and handle easily (AA or AAA) conect +(ve) and -(ve) terminals of the battery to the 2 speaker connections. If the spreaker is OK it will produce a cacling sound. If non, replace. If speakers are OK the trace connection from radio/amp to speakers. If OK then radio needs attention.
I had an issues where the my radio was working but no sound was coming out of the speakers. My problem was that the passenger speaker was disconected, and the wires were shorting out the radio. So I took it in to a pro installer and we put in a new speaker to the passenger door and hooked it up properly. The deck then started playing music fine.
Make sure your speakers are all connected properly, and that your wires have no cuts in the plastic that would expose the copper, causing them to short out. Also check your fuses to see if you blew any.
I have come to find out that in the 90's auto makers started installing factory amplifiers in their cars so they could use low wattage stereos in the dash. It's usually a blue wire off the stereo that runs the amp, maybe it couldve become disconnected? I also know that even if you put in an after market stereo, this wire must be hooked up or you'll get no sound from the speakers. hope this helps.
On many cars there is an exterior amp that the sound goes through before it is sent to the speakers. If the remote turn on wire isnt connected after you take your previous cd player out then the amp wont know when to turn on and therefore no sound will come from your speakers although your cd player is doing its job.
