Im trying to install a new head unit and I have power but no sound.  All speakers are connected properly.  I called circuit city and the guy told me that my factory amp might be going bad or speaker wires not connected right.  as I was inspecting my wires and removing the amp I realized that my speakers were going right to the unit.  My question to anyone is do I need the factory amp?  can I just run my speakers right to the head unit?

Is your amp coming on?  The head unit doesnt supply power to the speakers if you have your factory amp in the loop.  Sounds like you dont have right harness.

Your factory unit does not need the amp to power the speakers.  You can bypass the amp completely.. and like i said earlier you need the right harness for this.

You can run your speakers straight to the aftermarket unit. It will not sound real good when you turn it up loud but it will work.

what i mean is some decks do not have a built in amp e.g. 40x2 or 30x4 etc. the kenwood unit in my car will not work(has no amp) (sound out of the speakers) if i dont wire it through an amp

so far so good, it looked like a crimped wire going to my rear right speaker that may have caused it.  so I am going to run new wires to all speakers.  I got the rears done today, they were easiest, now for the door and dash.  As I was pushing the radio back into its spot there was a brief sound interupt.  Im wondering if there is a wire from old harness that is exposed and contacting metal.  As I drink my 4th whiskey Ill ponder.  Thanks for all your help tho.

Update:  So far I have both rear speakers hooked into the radio and they work, however I did notice where my problem might be.  When I first got my car it already had an aftermarket radio and speaker box with amp in hatch.  When I removed the box and amp to go with just the six factory speakers, I noticed that the previous owner had run the power wire for the head unit to the fuse box where there was a constant source and from what I assume is the wire bunch from the factory harness he had run the ignition wire from head unit to that bunch but no other wires in that bunch were being used.  Thats when I assumed the factory amp was not being used.  Now upon replacing the new unit inside the console I noticed the radio lost power when that bunch of wires not being used was moved.  Is it safe to assume that there is a short somewhere behind the console along that bunch of wires?  My ground wire is also in that bunch.  Im thinking the ground wire in the bunch is shorting, anyone any ideas?
