Installation in a boat. How to maintain the memory?

I am fitting the unit (Kenwood KDC-W3041) in a boat. I do not want it permenantly connected to the ship's battery for safety reasons so wish to supply an alternative source for the memory. Is this possible? What is the minimum voltage required for this?

Hi,

A possible method would be to hardwire a rechargeable 12V battery to the yellow wire and ground. The rechargeable does not necessarily have to be high capacity, Actually, a series of 10 AA 1.2volts penlight battery would do the job. Alternately, a small motorcycle battery would probably be better. Wiring wise, pls reference below diagram.

KDC-w3041 says PROTECTION when i turn it on


Sometimes if the power is removed it requires a code to be input, to remove the protection, you will have to contact Kenwood, and ask for the code to clear it. This is an anti theft feature. Often the car dealers have these, or try an auto-electrician.. BTW your English is good.

You will need to hool up the blue and white wire will need to be connected to the amp turn on in the vehicle. Hopefully you are using an installation harness to make your job easier. The vehicle has a small amplifier in it. it does need to be turned on when you turn on the stereo.

Kenwood kdc-mp239 car stereo overheating


Did you change the speakers, usually this happen because of the Ohms. Let me explain you, The factory radios are usally 8 Ohms and must of the aftermarket speakers are 4 Ohms or less so if you put 4 Ohms in a radio designed to work with 8 Ohms of coures is going to get hot first and them you burn it out.

When I plug my iPod into my car stereo, it's a Kenwood KDC-W3041, sound only comes out of the speakers in one door, but when I play a CD, sound comes from speakers in both doors. What's wrong?


If your using the aux plug in the front make sure the plug is fully inserted into the ipod and the stereo. then make sure all audio settings are set correctly. If you are using any other type of connection for your ipod ensure the connection is not loose.

Kenwood KDC-MP443U reverting to defaults


i don't think it will blow the unit if swapped...both of them should have power (~positive 12volts)...in the red wire power is supposed to cut off when you turn the ignition key to off...and the yellow wire is supposed to have power constantly(memory)

Kenwood kdc-w3041 protect mode


Hello ia737,

The "protect" display is probably being caused by a shorted or grounded (touching vehicle chassis or other ground) speaker wire. Check the speaker wires for bare spots, etc and insulate or replace as necessary.

You do not need to remove the fuses to force a "cold reset" of the W-3041. You can simply press the "reset" button on the front of the unit. It's the little recessed button at the lower left of the volume control. Use the straightened end of a paper clip or ballpoint pen to momentarily hold the button in.

Hope this helps.
