I have a kenwood KDC-MP245 , AM /FM/CD car audio player . When I crank up the volume the unit shuts down for a few seconds then comes back on . It continues to do this until I lower the volume , then it will stay on . The point of buying a better car audio cd-receiver was to have better sound and be able to crank it up . The better sound is there , but the crank it up .........not so much . Why ???

Hook up the power source to the battery, wire in some speakers.

Try putting the radio in standby mode and then hold the menu button in for a few seconds. Once you enter the menu, use the am or fm buttons to scroll through the menu. Then hold the seek up or seek down for a few seconds until the clock flashes, You should then be able to use the am/fm buttons and seek up and down buttons to set the hours and minutes. Once you have the time set, press the menu button again.

You may have a bad switch. You can try replacing the switch.

P. Cont wire that us usually blue and white

get in to "menu" (hold magnifying glass), scroll to "demo mode" (am or fm button), push volume knob in and hold for about three seconds. Should work, that's how I did it.

The KDC 334 doesn't have any audio input, so there's nowhere to hardwire an iPod or other mp3 player into the unit.

I'm sorry, but the only way to get iPod sound to come through this head unit is with a wireless gadget like the iTip FM adaptor.

press the menu button for a few seconds until the menu comes up, then using the am or fm buttons scroll until you reach clock, then press either the seek up or down button untill display flashes. then press the am/fm buttons to set hour and seek up or down to set minutes. when finished just press the menu button againl.

Have you tried the balance and fader control?
Also make sure the ground or - negative wire has a good connection for that speaker from the back of the unit. Or it could be the internal amplifier it self.

Your ground is weak or your running your radio at low voltage. Good Luck

Try the tiny reset button on the front just below the volume down button.
