In the manual in the troubleshooting sections it describes how to set the preout mode and that fixed my problem even after I had disconnected my battery.

The maunal states the if you press the display knob down towards am for at least 2 seconds it will turn on. However, for me it did work, but i recently disconnected my battery and now it doesnt work so good luck.

Subwoofer output: Hold the (AM-) button down for at least two seconds. You can do this function when "SWPRE" in is set to . The SWPRE (Switching Preout) Switches the preout between rear output ("R") and subwoofer output ("SW").

How many amp can be hooked uo to the Kenwood X792


Hello clay3227,

The X792 has 3 pairs of preamp outputs, so you can directly connect a 4-channel amp and a monoblock amp for subwoofers directly to the receiver. If you need additional amps connected, you can use RCA "Y" cables to split the signals. Also some amps may have preamp outputs that allows you to "daisy chain" more than one amp to the same set of outputs from the head unit.

Hope this helps.

I have a kdc mp632u and i cant get any sound out of my subwoofers. The amp comes on and there is power to the amp but still no sound. can someone tell step by step what i have to do to get it to work with...


Hello,

First, make sure that the RCA's from the HU to your amp are properly connected, and fully seated on both ends. There are 2 sets of outputs. You should be using the ones on the left as you face the rear of the HU. Here is a link to the manual. Page 40 shows the connections on the back:

http://inform3.kenwoodusa.com/manuals/KDCX590.pdf

After making sure that everything is connected OK, check to see if you have the subwoofer output turned on your MP632U.

To do this, push the control knob on the right toward AM (toward the bottom). Subwoofer output switches off/on each time you push it. When it is on, the display reads "SW ON".

If this does not solve the problem, you most likely have a defect in either the HU or the amp.

Hope this helps! If it does, please rate as "FixYa." Thanks!

CD player wont come on was doing weird things


You have your accessory wire (red wire) and remote ran together and the yellow (constant wire ran separately in the dash?

You need the red wire to so you can use accessory and to turn off your cd player when your vehicle turns off.

You need the yellow wire to keep all your settings stored. base/treble/time clock

Just a little clarification. Your amp turns on with the remote wire (blue) wire, if that is not hooked up you will get no power to the amp.

Here's the in-dash diagram to your vehicle at the bottom of this pdf.

You want to focus on N,O, and P

Do you happen to have an after market wiring harness? These can be bought from walmart for your vehicle. You just take the male end connect the colors together and plug end that goes to your cd player into the female end. Very easy to do.

You could also have one of these fuses out under your hood, that might cause you to lose power to everything.

No sub when listening to a cd


you're using the wrong remote output wire. You have it hooked to the power ANTenna wire (blue) which turns off when not using the tuner. You need to use the REM OUT wire (blue w/ white stripe).

Audio Output problems


Currently you have the blue wire from your Kenwood head unit connected to the blue wire in the Chrysler wire harness adapter. You need to disconnect this wire, and reconnect it to the blue/white wire coming from your Kenwood head unit instead. You probably already have the remote wire from your subwoofer amp connected there; both wires need to be attached to the blue/white Kenwood remote output. Your LHS is equipped with a factory amp. The blue wire in the Chrysler harness activates the amplifier, but it's connected to your Kenwood's power antenna activation output; therefore it's only being turned on when the tuner is selected.

My deck doesnt not transmit signal to my amp. Is this an rca cable problem


Hi Your problem is almost defenetly that one speaker is hooked up with reversed polarities, making one speaker cancel out some vibrations of the other speaker. So get the wiring phase checked again, its ethier this or a fauly cable. Good luck.
