radio muting itself

yesterday i was installing an amp in a friends car and when i went to connect to connect the remote wire to the blue and white wire ont the radio, which i normally use the radio would mute itself. the radio he has is an aiwa, i have no idea what model it is or anything like that. i even acidentally touched that same wire to the chassis of the radio and the radio muted. i have done plenty of sound systems and i have never had a problem or complaint. i want to know did i do something wrong or is the radio just bad. also is there anywhere else that i could run this remote wire to so that the amp will come on. i tapped into the yellow and red wires, the amp would come on but i would get notthing but distortion from the subs. the amp is a legacy amp i believe and the speakres are infinity. i am installing this in a 89 regal.

If you touched the blue / white wire on the Aiwa to the chassis, you directly shorted the remote on lead from the deck, if this line does not turn on the amp, you have caused damage to the circuit in the radio itself. Now you can hook that remote on wire from the amp to the red ignition wire as a temporary fix, if you are getting nothing but distortion from the subs ensure that the crossover is set properly, the gain turned down and listen again, if you still have distorted output then you either have a blown output section in the cd player that is causing the noise, a bad amplifer (suspect) or blown subwoofers. I am assuming that the subs are new so they should be OK. You can do a whole pile better than a Legacy amp though, if it is what you had, time to shop for a real amp, if it is all you could afford, take it back and get another.Top Secret, I can tell you but then my wife will kill me.

the wire never touched the chassis until i did it by accident. the radio was muting before i even had it touch the chassis. i personally think its the amp though because he bought it used from someone for like 50 bucks which was 49.95 too much. i thought maybe i was doing something wrong but turns out he went to bestbuy to day and they told him the radio is a piece of junk. thanks for the info though
