Ok i am not a novice but not a pro either, My ram has the standard stereo system in it. Headunit is the single cd system 6x9 front doors and 5 1/4 rears no satelites in the dash. I replaced all the speakers with new infinity speakers tested with the head unit only works fine. Then wired in a 4 channel amp using the high inputs.(yes i know ,i should use some converters but i didnt). the amp is working. the rear speakers sound great but no output on the front channel and the protection is not on. the amp is getting the input , just no output. I believe this to be an issue with the head unit. all wire ohmed out from the amp to headunit, no shorts or breakes. Is it possible for the out put to be to high on the head unit? Thanks in advanced,

well i am assuming no one has a clue or even a guess about this. I dont mind even guesses as i am at a complete stand still at the moment.

I would switch the high imputs around and see if the fronts work then and the rears quit. That would tell you if you have an input problem. If the rears still work then and the fronts don't I would check for a front speaker terminal that might be grounded. If you have a grounded front speaker that might shut down the output to both fronts from the amp. let me know what you find out, be glad to help you further you may just have a couple of bad channels on your amp

I think Charles has the best suggesion for you, you need to issolate the problem and figure out if its the input side of the amp or the output side of the amp. You can also try disconecting one speaker at a time in the front to see if you have a blown speaker, but since you said the factory deck ran them fine that is very unlikly

ok well believe it or not i removed the ground wire on the high input connector and now all speakers work, down side to this is now the fade and left, right is funky, so seems to be a floating ground on the system. if i ground it fade and left right works but only for the rear it kills the front. any suggestions?

If you connected the input wires according to the manual's instructions for common ground vehicles, which includes using the ground wire, then the wiring is wrong. Each wire should be connected to the corresponding speaker wire lead. If any of these wires are mixed up, the problem shows up in fade and balance. But on the other hand, I spent one long frustrating time recently trying to figure the same thing out with the high level inputs on my four channel amp. Turned out the input on the amp was bad, and aftermarket LOC's did the trick.

on the factory wire harnes there are two BLACK/ green wires directly after the speaker wires that are grounds should i try grounding them to the high input ground wire? i am refering to pin 21 and 32. as far as the speaker wiring i have rechecked it and they are correct and in phase. and the amp is set to 4 channel.

Grounding those wires should have no effect at all. Touch them to metal and you will see, nothing happens. But I referred to the wiring diagram for the high inputs of the amp, where if you were wiring for a common ground system the wiring is different than wiring for a floating ground car. When you said you disconnected the ground wire on the input connector, it made me think you may have wired according to common ground. So if you have tested each of your leads connected to the car's speaker wire harness for the proper speaker position and polarity, and have them connected to the correct wires on the high-level input plug, then the high-level input on the amp may not be doing its job properly. Which is why I, from my bad experience, would just use a separate LOC right from the start. I looked again at your question. Should you connect those ground wires? Doing that should make no difference either, and wouldn't hurt anything if you did. But not necessary. ------------- Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.
