Question about Kenwood KDC-128 CD Player

1 Answer

No sound from speakers

I just replaced the rear speakers on my car, and now when I turn up the volume past the "20" level, all the speakers (front ones too) turn off. If I turn off the car and start it back up, the speakers will work again, but will again shut off inexpicably when I hit the magic "20" level. Anyone know what could be causing this?

Check the value of the fuse for the power feed, it could be that the fuse is to low. The unit uses 10A min. I suggest a 25A fuse. here's a manual http://inform2.kenwoodusa.com/manuals%5CKDC1028.pdf Luck

Ouku single din no sound from rca cables


Sorry I did not use the video out RCA cables. My audio RCA cables worked fine... I ran them to my JBL amplifier through a conversion adapter. I did not run it direct to the amp.. I used Metra TYTO-01 03-08 Toyota Vehicles Harness for JBL SYS (Ebay item 160560648718) and it worked great.

Here is the wiring color coding that I found online:

When I do a noise test I get no sound out of the woofer. I am getting no bass from the woofer


These are "decent" quality 5.1 speakers, usually without any trouble.

Now, to your question, you will not have 5.1 "surround sound" effect with standard sound card, standard sound card will provide only three speakers sound, rear speakers will not connect but bass should be hear. Please switvh power off to the speakers and disconnect all cables from spaekers and connect them for best quality as follows:

1. Audio from PC, orange, green and black connecting to front right speaker.
2. DB15 (D-SUB) connecting to subwoofer, subwoofer is serving as mixer, power board, amplifier and connection box, control pod is just cable connection to it
3. Connect all cables to they respective speakers

Establish location of the speakers, from experience, in ideal world:

1. Sub should be on about your knee level or below, about twice your hight from you.
2. Front centre speaker should be about some distance as sub or bit closer on front and slightly above your head.
3. Front left and right speakers should be at about 45degree from your axis, at distance of about 1.5 your hight and on the level of your head or slightly below.
4. Rear left and right speakers should be located similiary to front speakers, on they level or slightly above them, again, about 45degree from your axis.

Location of the speakers is more actually important than it is assumed, total sound immersion is not possible without proper speakers installation. Head in these instruction meant a location of your head while you are listening to your music or recording not while you are standing.

In reality... hang them higher than your head in four corners of your room, front centre higher than sides, woofer lower than sides and below front centre, if they interfere with each other - increase the distance. I hate reality...

After speakers are connected:
1. Plug power cord in,
2. Turn all sounds totally down, including subwoofer
3. Increase sound on PC to maximum, let play any known to you music, tufftuff or bach, whatever, do not bother with metallica as you cannot discredit on it correct levels.
4. Increase subwoofer volume, holding one hand on the front of the grill till you get some vibration from it
5. Increase sound on centre speaker, then on sides front speakers till you achieve equality of the sound
6. Decrease sound volume on your PC to about 60% - 70%
7. Increse subwoofer volume till you feel sound on your hand in front of the speaker.
8. Increase sound volume on front/rear speakers as required.

Hope that short intro solved all your speaker problems, enjoy! if you require any additional help, do not hesitate to answer to this post with request.

I bought these x 240 speakers used. do i need a driver to run them? where do i connect the plugs, black and green?


These are "decent" quality 5.1 speakers, new were on about $100.00 to $150.00, have two years warranty from time of purchase.

Now, to your question, you will not have 5.1 "surround sound" effect with standard sound card, standard sound card will provide only three speakers sound, rear speakers will not connect.

Connect speakers as follows:
1. Audio from PC, orange, green and black connecting to front right speaker.
2. DB15 (D-SUB) connecting to subwoofer, subwoofer is serving as mixer, power board, amplifier and connection box
3. White plug is connecting to front left speaker
4. Red is connecting to front centre speaker
5. Black is connecting right rear speaker
6. Yellow is connecting left rar speaker.

Establish location of the speakers, from experience in ideal world:

1. Sub should be on about your knee level or below,
2. Front centre speaker should be about twice your hight distance from you, on front and slightly above your head.
3. Front left and right speakers should be at about 45degree from your axis, at distance of about 1.5 your hight and on the level of your head or slightly below.
4. Rear left and right speakers should be located similiary to front speakers, on they level or slightly above them, again, about 45degree from your axis.

Location of the speakers is more actually important than it is assumed, total sound immersion is not possible without proper speakers installation. Head in these instruction meant a location of your head while you are listening to your music or recording not whil eyou are standing.

In reality... hang them higher than your head in four corners of your room, front centre higher than sides, woofer lower than sides and below front centre, if they interfere with each other - increase the distance. I hate reality...

4. Increase subwoofer volume, holding one hand on the front of the grill till you get some vibration from it
5. Increase sound on centre button of the right fron speaker till you achieve equality of the sound
6. Decrease sound volume on your PC to about 60% - 70%
7. Increse subwoofer volume till you feel sound on your hand in front of the speaker.
8. Increase sound volume on front/rear speakers as required.

Front speakers only produce static


The amps are on each of the speakers. There is a place in Florida that will fix them for around $85.00 each plus shipping. I put a sony unit in mine and replaced all of the speakers with the kicker ds series for less than fixing the bose system.

Volume fade


Check to be sure there are no speaker wires touching ground, and that the wires are connected in phase to the head unit.
Front Speakers 5 1/4" Doors Left Front (+) Green Left Front (-) Black/White Right Front (+) White/Red Right Front (-) Black/White Rear Speakers 6" x 9" Rear Deck Left Rear (+) Pink/Red Left Rear (-) Pink/Blue Right Rear (+) Pink/Light Blue Right Rear (-) Green/Red

The symptoms you are relaying definately sound like an internal amplifier problem. It is fading in and out for a reason - usually due to heat.

Have you had the radio bench tested (seperate from the car) to eliminate the car as being the culprit?

Since the radio was run with damaged speakers originally, the output or amplifier power supply on the amplifier may be bad.

As an alternative to repairing, I would suggest investing in a small 2 channel amplifier to power the speakers.

The radios claim 50W per channel, but in reality give 12-15W RMS power.

A dedicated amplifier with built in crossovers and gain adjustments will prolong the life of your speakers and add to the tonal qualities of your new speakers. Instead of turning up the volume on the head Unit, and sending out a distorted signal that will blow your speakers, an amplifier will give more CLEAN power to them, so it will be louder at a lower volume setting.

This will bypass the internal amplifier on the radio, and send a Low Level signal ONLY thru a set of RCA cables.

Good Luck!!

Rear speakers don't work


Speaker test confirms whether the speakers actually work but not the sound level you have them set at. Chack volume level of each speaker. This may be a separate button all itself.

Rear Speaker volume too low


Channel level output can be adjusted in the menu if you have the remote. Set the rear channel level volume higher and the fronts lower if need be, and then turn up the volume. Enjoy!
