Everything is working fine with the stereo, but I am getting no sound from speakers. I had the RF factory system. Could somebody please help me with the wiring to get sound from the speakers. Help Help

Start at the beginning. What have you done? What haven't you done? It's working fine, but there is no sound. How can this be? What exactly have you installed?
Sorry but I cut class the day they discussed mind reading, so you are going to have to help us out here.

I used the Metra wiring harness and have all the wires hooked up. I have power and cd is playing fine also. I checked it out by getting and old speaker of mine and hooking it up to the FR wire from the Kenwood. Though, when i hook up the harness I am absolutely getting no sound from speakers. Honestly I feel it has something to do with the RF being there first. I write to you because I noticed you have installed an aftermarket HU replacing the RF unit, and that is exactly what iam trying to do. How did you do your wiring?

Are you aware that there is an external amplifier in the RF systeem? I suspect not. It is located almost against the firewall just above the brake pedal. If you want to use the existing speaker wiring it will be necessary to unplug the two connectors from the Nissan amp and jumper the necesary wires accross on the blue/black plug.
As it presently sits the output of the Kenwood is playing into the inputs of the Nissan amp, but since it is not turned on (the amp-on wire is not connected) there is nothing coming from the speakers. You do NOT want to use the Nissan amp so it will be necessary to add jumpers as I indicated above.
If what I suspect is correct, let me know and I will provide the info on the necessary pins to add jumpers to.

I believe one of the reasons that you are getting no sound might be that the RF system has an external amp. I believe you have to bypass this amp to get everything to work correctly. I'm not sure how people are doing this, but if you do a seach in the forum you'll probably find your answer.

Attached is a sketch showing which pins to crossconnect on the plug to get the front and rear door speakers to work. Orientation of the plug is facing you (pin 5 on your left) with the locking clip up. You will notice that the dash speakers are not connected.

How to make the jumpers: I used male pins purchased at an electronics store which will just fit into the sockets on the plug. I used short pieces of speaker wire (about 3-4 inches long) and crimped the pins to stripped ends of the wire. I wrapped each pin in red and white electrical tape using one color for "+" and the other for "-". Wrap all metal of the pin that does not fit into the socket, these pins are very close together when in place and one does not want them to short against each other.
Once all pins are in place, wrap the plug with electrical tape to hold all pins in position. Make sure all speakers work then secure the connector under the dash.

AWESOME!!!! Thank you very much. Though, is there anyway for me to get my tweeters to work?

Well, there is a way. I have mine working. I used a couple of Radio Shack crossover networks. Using the pin into the plug technique, I connected the input of the crossover network to the front output (amp input) of the HU, connected the lowpass side to the door speaker and highpass to the dash tweeter (do this for both sides, L and R, one crossover for each). I placed the crossovers into plastic boxes and have them tucked under the dash. The center dash speaker does not work. I felt it was entirely too much hassle to get it to work for the little it would add to the sound system.

You da man!!!!!!!!!! I greatly appreciate you sharing all the information with me. It definitely made my day. Thank you again.

How do you like the system I have been looking at the same unit for a couple of weeks is it worth the money. Did you do the install yourself ? How did you mount the unit in the dash.
