it could be several things, it could be a bad ground, a bad power connection, a bad speaker(s) or the deck itself could be bad, i would check all your connections first. if they all check good try disconnecting one speaker at a time.

try checking your speaker wiring and speakers for shorts or grounded wires.

Most head units come w/ connections for both auxiliary units (for an amp, etc) and the line for the power antenna. in the past when my deck would stop sending a signal via the auxiliary, I would simple use the power antenna. It pretty much just lets the amp or whatever know when to turn on. Separately however, most newer decks have a way to turn off the auxiliary via the menu settings. I might start w/ that if your kenwood happened to be a newer deck.

try checking your speakers and speaker wires for shorts.. if that is not it you may have a bad output ic.

For these kinda devices the security can not be by passed ..and there isnt a master code to delete the old one ...The security code it is stored in a flash tip memory chip inside..and it is not sensitive on any power removal or any other trick cause it is not a memory that depends on power feeding to hold the information ...so ..the only way to do it ..is to take it to a rep[air shop that handle this kinda devices..and change the memory chip that hold the code...after that you will be able to insert your own code..or ..if it is not a new chip ..they will tell you the new code..
This operation it is well known among guys that handle this devices..cause it is a problem that is present among almost all second hand cars buyers ..and it is the only solution ..

sorry, if there was thieves would just love it, radio and serial no. and they may ask for proof of purchase

check your speakers and speaker wires for shorts. if they check out fine, you may have a bad deck

So you connected your MP3 player into your auxiliary input of your car stereo system?

Hi! Does it have the same wiring harness from the old one? If none then theres a problem. Something might be grounding. May I know what was the old cd player? Thanks!

The only wire that you should hook up from the amp to your head unit is the remote power wire which is the blue wire on the wiring harness for the head unit. Sometimes they are blue with a white stripe. Hope this helps.

check to make sure the ohms rating on the speakers is correct. should be equal to or higher on speakers compared to receiver.

If this happened while playing music at a little higher volume, you must check the speakers for short in coils. disconnect the speakers to see if the protect condition changes, if so check the speakers and wiring. If not then you must have blown up the output IC or a power shorting within the set. You will have to remove the pcb disconnect the power to the output IC to confirm the fault. Helpful I hope. Good day

You cannot override the code, you will have to take it to the nearest service dealer.
I'd appreciate if you rate this 4 thumbs if I had helped you. If I couldn't help you please rate accordingly.

This happened to me. What worked was turning off the ipod (not stand by mode). Turn it back on and plug it in, it should work.

Here is a link to the owner's manual for the stereo:

In order to access the AUX option the source needs to be in standby mode. To do this, just hit the SRC or source button until you reach the standby option. Now hit the menu button and scroll up or down until you reach the AUX on/off option

there is a chip when you open the case up at the back you will see some white putty around it there are also a bunch of prongs coming out of it. that is bad
