SOURCE: Kenwood KDC-138 Operation Problem

Here's the quote from the manual regarding "dcer": "The speaker wire has a short-circuit or touches the chassis of the vehicle and then the protection function is activated. Wire or insulate the speaker cable properly and press the reset button. If the "PROTECT/DCER" code does not disappear, consult your nearest service center "

I believe the manual can be downloaded from crutchfield .com after you go to the Kenwood KDC-138 page on their website. The reset button is either on the lower left of the face or, removing the face, on the lower left of the body. Hope this helps you.

I have Kenwood kdc- mp343 it displays protect then what happens?


Disconnect all speakers from unit. Turn on. If still in protect then unit is damaged and needs repair. If not then reconnect 1 speaker at a time until it goes into protect. That speaker is either shorted or wiring is shorted.

My JVC cd receiver model Kd R-310 reads protect on the display and won't work. I cut the wires to try to install it in my 2002 grand am. Can this be fixed?


Repair cost would exceed replacement cost. Try disconnecting all the speakers and see if it works then. Try reconnecting each speaker by itself and see if that causes the problem. Most grand am have the monsoon sound syatem...even if they aren't labeled as such. Pull the carpet in the trunk on the left (drivers) side wheel well. The monsoon amp is located over the wheel if you have a monsoon system. If you have to remove the amp then you must change the speakers out or rewire them as the monsoon system uses bi amp speakers. Most of the ga forums have extensive write ups on this system.

New car head unit, same old problem: Garbled sound


Hello susanmillan,

If it's not the head unit, and it's not the speaker, then it must be a problem with the wire going to the speaker. When you hit a bump, the wire shorts or opens intermittently causing the faulty sound. Some insulation could have rubbed off. There could be a bad pin in a connector. The wire could have some broken strands. It could have become pinched against something sharp.

The good news is, it's really an easy fix. Just have your installer make sure that the sound is OK at the wiring harness itself, and run a new wire from there to the speaker.

Hope this helps.

It is flashing the word protect on the screen


You have a shorted speaker wire or a blown speaker. The unit is protecting itself from damage. Did you install it? if so, pull the deck and check your connections. If they all seem fine, disconnect one speaker at a time, and turn on the radio. Make sure the radio speaker wires are taped so they don't short and cause more damage. Test each speaker wire until you find which one is causing the problem. Now re-connect all the other speakers and test. Next, disconnect the speaker wire right at the speaker that's giving you a problem, tape it off, then re connect it to the receiver. now test again. If all is ok, you have a bad speaker, if not run a test wire from the radio to the possible bad speaker and test again. If the speaker plays, you know what the problem is, replace the bad wire. Most often it's a door speaker wire or a wire got pinched during installation and took a while to short. Hope this helps

No volume


Protect is on because one of your speaker's or wires is shorted out. It comes on to protect the amp from frying, check ALL of your wiring and speakers for shorts to ground, NONE of the speaker wires should go to chassis ground only the stereos negative (-) speaker termina.l
Checking your speaker is easy, take a (D) cell battery and a couple of wires and connect the wires to the speaker, you should hear a click if the speaker is working properly. Good Luck
