Default Two Amps Installed but One is cutting out

It sounds like undervoltage protection. Make sure your wiring and
connections can handle the combined power draw.

Anything more than a loss of 0.5V at peak currents could cause problems.
The voltage loss is resistance/foot * feet * current. To address
heating, multiply the voltage loss by the current again.


For example of what would be a disaster of a setup:

100A peak
40A average
7 feet of 12 guage wire (.00187 Ohms/foot for 12 guage)

.00187 * 7 * 100 = 1.3 volts lost at peak current
.00187 * 7 * 40 * 40 = 20.9 watts average wire heating


Thanks. I'm running about 10ft of 10 guage to a distro block and another 1
1/2 feet form the distro to the kenwood, then i'm running what looks like 16
guage from the distro block to the road gear amp. Could that power to the
road gear be making the kenwood cut out? I have extra 10 gage that i can run
to the road gear, but I will pick up some 10 guage grounding cable for it
too.

What are the ratings for the amplifiers?
