troubleshoot this wierd radio issue
 

ok long story short, kenwood kdc-x997 brand new i have a 4 channel amp and sub amp all work great. when i turn the internal radio amp off i lose my sound now heres whats wierd the amps stay on radios on just no sound, i tripple checked my wiring its all good. this is where it gets wierder if i turn internal amp off while cars on my sounds is on once i turn the car off and back on sound is gone. now with internal amp on the sound never turns off. i should be able to turn my internal amp off like i have with every other radio on the past. i cannot figurte out why its doing that any ideas? i dont have factory amp or onstar from stock radio its just my 4 channel my sub amp and my head unit.

Did you buy the harness adapter for the car? It is a little box that mounts under the dash and plugs into the factory radio harness. I would guess that it would either be that, or your internal amplifier is shot.

The problem that you seem to have occurring is usual.. That option is for when you go up to the DB meter and you want to turn off the highs amp to prevent blowing your speakers under a burp. I noticed that option on my old KDC-X496 and it was very handy testing out subs without annoying people with my profane rap music lmao. Keep that setting on cause its the internal amp in your head unit not your car.

Also check and see if the mute wire is not getting grounded.. that will cause all kinds of fishy stuff to happen..
