How do I turn the volume up on my Kenwood car stereo so I can hear the other people on hansfree with my iphone

This could be due to a faulty speaker relay (if your unit uses one). Normally, the unit will "wait" a couple of seconds after you turn the unit on. Then you will hear a "click" and the sound will begin coming through the speakers. If the relay is faulty, it would cause the problem you describe.

I had a similar problem with the DDX470 in a 2003 Hyundai Sonata. Turns out the car has a factory installed amplifier so the Blue/White wire had to be connected to the Blue/White wire on the wiring harness I had connected to the car. Let me know if you have this wire connected or not, and what type of vehicle you are installing the stereo into.

Of course it has no volume the KT56 is a radio tuner! It needs to be connected to a power amplifier to hear anything. The audio out sockets need to be plugged into a stereo amp that has speakers. The KT56 is not a stand alone device!

• Check to see if the sound on the stereo receiver has been muted.

• If the stereo receiver has a headphone jack, make sure

no headphones are connected.

• Try a different audio setting on the stereo receiver.

• Check the speaker wires to make sure they are

connected securely to the stereo receiver.

• Try connecting different speakers to the stereo receiver



If these have already been done,

Symptoms still persist, service may be required.



hope these helps,

thanks for choosing Fixya for assistance.

My electronics savvy source says you may be overdriving the amplifier in your Kenwood stereo to an impedance-mismatched set of speakers, meaning that the speakers are impedance mis-matched to the Kenwood stereo, and therefore operate ok (but inefficiently) at low volume, but cut off completely at higher volume.
Fix: match the impedance of your speaker network to the specs on your Kenwood car stereo. Once this is done, you should be able to crank up the volume to the point of permanent hearing loss.
SAFETY CAUTION - sound levels above 85 decibels produce NIHL (noise-induced hearing loss).

Sounds like you need to send it in for service.

Hi If anything the stereo was probably designed and tested using a certain version of the Iphones software, now that version 4 has been released the way the IPhone communicates may have changed.

As a result the stereo is no longer able to talk to the phone and vice versa. your probably best off contacting Kenwood direct to see if they are aware of this problem and if there is anything that can be done about it.

You can buy a thing(not sure of exactly what its called) that you plug into your iphone and you pick a radio station on it and turn your stereo to that same station and listen to your itunes

I had this same exact problem when my last older Kenwood Marine stereo cooked itself while I had it up loud for a few weekends on the lake. (smelled like it had burned inside). I went out and bought a new Kenwood KMR-550u stereo deck. (I do not have an additional amp). I hooked it up to the exact connections where my older Kenwood stereo unit had been hooked up, as I never had a problem with this for the past three years until it failed after smelling of burning elelectrical. I had chalked the problem up to heavy rain we had one day. Every time I turned up the volume, sometimes up to 27 out of 35 possible, or 29, or 32, the stereo would suddenly shut off as if I had turned it off. After a few seconds the stereo would come back on, but unless I was quick enough to turn down the volume it would do it again right away. Of course on a boat, we were beached in a cove and the engine was not running when I encountered this. I searched the internet finding hundreds of similar complaints and several dozen theories of all types, but only a couple that pointed me towards the power (voltage) idea as the problem. I put a volt meter on the positive & negative wires powering the stereo. I watched as I gradually turned up the volume, the voltage on the power wire gradually decreased from 12.5 volts, down into the 11 range, and as it hit 10.9 or 10.8 volts it shut off typically around a volume of 32. The red power wire in my boat that never seemed to have an issue with my old stereo until it fried was determined to actually be inadequate for the power flow for the new Kenwood, and probably was the culprit of my failed older unit. I offer this sound advice: Run a new pair of positive & negative wires directly from the battery (with an appropriate fuse of course (the deck has a 10 amp fuse in it's back so I would use that at the battery) to the stereo. Check the voltage as you turn the volume up into the high 20's and low 30's to ensure you are still getting voltage in the mid to high 11-12 volt range. The stereo is designed to require a minimum of 10.8 volts to operate, and when it drops below that it protects itself and shuts down.
