Question about Kenwood Audio & Video Receivers
Remove the receiver and see the connection given to left speaker follow the same for right speaker .........the connections will be similar only.........

Since it was just recently installed, would it be safe to assume that it is fairly new? If yes, perhaps your best bet would be to return to dealer/manufacturer for repairs/replacement. It is highly probable that the unit has sustained major hardware fault at least on the right channel. Even if it were just a fuse, it would still be to your advantage going that route.
Should for some reason you would venture a DIY, diagnosis and repairs of course would require fair familiarity with electronic components and circuitry, use of a VM and a soldering iron and preferable access to a service manual or at the very least a schematic diagram with voltage readings.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.

It is possible that the amplifier had encountered a fault with a higher current drain which had triggered it to a protection fault condition. The fault can be with your output drivers. Please check for short on the outputs fitted for both the channels. Use a meter after disconnecting to check for short in the drivers. Disconnect the positive and negative voltages to the output and see if the protect changes. Even a fault in the preamp stages that drives in high current into the output can shut the Amplifier. Sometimes this can be a noise which can be a HUM or HISS before the protect works. Faulty capacitors in these circuits also can cause similar issues and needs close observation.You need to confirm and replace the specific stages or outputs. If not there can be issues in the mother board. Maybe the protect circuit by itself is shutting off due to a faulty bias or there is a leak in any voltage/current sensing circuit. Also disconnect the speakers and test, if the amplifier comes out of the protect mode then check for short on the speakers.
