I have a kenwood cd Head unit along with a second cd player.
Top HU is a KDC-716s
Bottom is a KDC-D300
Problem:
With the Head unit in operation, I get sound with all four interior speakers along with the sub. But when I remotely switch to the bottom cd player to play music (KDC-D300), only the two right side interior speakers along with sub work and not the two left side speakers.
I removed both HUs to see what the wires look like in the back. It appears it has two wire harnesses. One to the HU and one to the cd player. Nothin seems to be loose.
The model number of the working head unit is KDC 716s according to you. I looked it up and it has an inbuilt CD player.
Why on earth do you have a second CD player installed along with the first? This is confusing me and making it difficult to envision how you have the systems wired.
Please provide more details on the above, as well as a list of all components in your system - with that information I’ll attempt to provide some help.

The system plus wiring was done at Professional shop …10 plus years ago. BUT not the interior speakers and head units. As I changed those several times.
The second cd player has cool graphic displays and works as an equilizer. It works as a “CD changer” if you will. I don’t see why not?
I have nothing major. Just a simple set up.
Head units stated above.
two JL audio fronts
two JbL back
350 watt amp bridged.
From what the newer 301 manual shows is that is a slave unit with spectrum display and no eq loop. It hooks up with standard bus cable. Since the both sides works fine from the radio, I would suggest to look at the cable connecting the two units for damage.
So I found the Owner’s Manual for the slave unit online.
Take a close look at page 10, which I’ve screen-captured below.
You can see that there appears to be two connection points in hooking this slave unit up to a master unit.
The first is the bus cable, which provides control over the unit from the master unit. If you’re able to control the slave unit from the master, my guess is that the bus cable is properly connected.
The second appears to be a simple 2-channel analog audio connection, which requires a particular input on the master unit to work properly. I’ve highlighted it here:
Based on your description of the problem, it seems that this is where you should focus your troubleshooting attention. I hope this is helpful to you; let me know if I can help further.
The speaker wire inputs are for the dancing light display and have nothing to do with audio output.
The audio signal is transferred through the bus cable. If the cable is good, then the slave cd player output is bad or the master cd input is bad.
Make sure to wiggle the cable and connector while playing to see if the left side comes back. The wires inside the cable and very small and can be damaged without any signs of outside physical damage. If wiggling stuff around makes it comes back on, it could also be a bad solder joint.
Seems that theres a little conflicting infomation about the bus cable and the speaker input cables. Ohh well, like you said, I’ll wiggle them both one at a time with power on to see whos the culprit. btw, i don’t think the wires are soldered.
I haven’t examined the wires up close yet but how are the input slave speaker wires spliced on the master units wire harness as shown in the picture? How does that physically look like? connectors used?
I was thinking of redoing that portion. maybe there is a bad connection on one of those connectors.

I look into that this weekend thanks. Do you know how the input cables on the slave unit spliced on the main harness?
