Question about JVC Car Speakers & Subwoofers

1 Answer

I am trying to install a JVC KD-S34. I have tested all the power lines, and they all have power when they are supposed to. Light line comes on with the lights, switched line comes on with the key, and continuous power is always on, yet the unit does not seem to get any power. Nothing happens when I plug it in. Have tried reset button, and nothing. Any ideas? Thanks, Brian

There should be 2 power cords , one yellow and one red, ensure both are connected and the input power is sufficient

I have a jvc kd r310 cd player and im running a 4 channel amp and 2 subs. How do i hook up another 4 channel amp to run my door speakers and rear speakers


There should be a "line out" on your amp. Take a pair of RCA patch cable and run it fron "line out" of the 1st amp to the "Line in" of the 2nd amp. Then wire that 4ch amp for your speakers.

I have a jvc KD-G320 deck and need help hooking up subs...


Hello c92bivens,

While your KD-G320 does not have a specific subwoofer output, Kenwood did make provisions for adding one. There are two stereo pairs of line outputs on the back, one each for front and back. On the set for the rear, you can select a "line output mode" of "REAR" for normal speakers, or "WOOFER" for operating a sub.

Page 14 of your owners manual details the setting procedure while page 31 shows the connections. The manual incorrectly refers to the FRONT line outputs on page 14. Use the REAR line outs instead. If you do not have a manual, you can download the PDF version here at Crutchfields's web site. Ignore the "DISCONTINUED" notice (it's an old head unit), and scroll down the left just under "What's in the box" and click the "download owners manual" link.

Hope this helps. If it does, please rate as "FixYa".

While testing before final installation of the JVC KD-G240 CD Player, the only power I can get is to eject a disc and temporarily display the time. I cannot turn the unit on. After pressing the reset...


This is an indication that the "ACC" line is not getting the 12 volts to turn on the radio. Check the fuses, it may have blown one. The "ACC" is the red wire that comes off the back of the radio harness. It needs a 12 volt supply when the key is turned on for the radio to work properly. When this is missing, you will have the conditions you have described. The yellow wire is for a constant 12 volts even when the radio is off and the car is off. Since you do get the eject and the clock display you have a good ground, so that is not an issue. You just need to find out why you do not have the 12 volts on the red wire when the key is turned on in the car.

My JVC KD-623 Car deck is recieving power as the stand by light is on but it will not turn on or eject the disc. It was professionally installed.


there is two power sources to head units, one is a constant that makes the unit remember the time and such and the other is to actually run the unit. So am I correct to assume that the unit does not come on when the car is turned on? If so, check the wiring for the ignition

Hey there,

There are two power wires to consider when installing an in dash receiver. They need to be connected to different sources.

Red gets +12VDC when the Ignition is ON.
Yellow gets +12VDC all the time (Fused line straight to the Battery).

The yellow is most likely the problem. If it's power source is interrupted, the unit will 'forget' it's settings.

Double check your power sources (for both red and yellow) and get back with me (either way),

Remember: Good things come to those who Rate!

Manual for jvc kd-lh811 car stereo


You can check here for all of JVC owners and installation manuals, but your model number did not come up when I did the search for it. You may want to try using the KD-LH810 manuals, it may be the same as yours.
