the search yeilded no answers, I have a mach 460 stereo and the tweeters are the only speakers working, what fixes or things should I look for

if you still have the factory radio in the car then you need to start checking fuses. No, we do not know which ones and I am not going to try and figure out my manual to tell you. Go out to your car and start pulling one fuse at a time and look at it to see if it is blown, look under the dash and the hood by the battery.

If you replaced the deck and then noticed that it died, it is because you did not connect the amp turn on(blue and white on the car side fo the hrns) to the remote turn on from the deck(blue/white or blue). page 2 of my cardomain page shows the 460 integration.

No blown fuses I checked that prior to posting, It is the stock head unit.
