Default Two Amps Installed but One is cutting out

The Kenwood is about a 4 x 35WRMS I'm guessing.. I don't even remember
the
model O_O

The Road Gear is a *claimed* 2 x 40.. but since it's road gear i'd guess

its
about 2 x 20 or so.

That's about 35 amps peak.

0.00118 * 11.5 * 35 = 0.47 volts

You're pushing the limit with such a long length of 10 guage wire. Add
in other losses in the junctions and you may be loosing enough to trip
undervoltage protection.

Pick up some 8 or 6 gauge wire for your setup. It's not too expensive
and it's not so big that it becomes difficult to work with. Avoid weird
improvisations on the connections. Solder them or use properly sized
clamp connections.

8 gauge: 0.000739 * 11.5 * 35 = 0.30 volts
6 gauge: 0.000465 * 11.5 * 35 = 0.19 volts

Moving the amps closer to the battery helps a lot too. If you have
enough clearance for ventilation, putting the amps under the front seats
could cut the wire length, and losses, in half.


Cool Thanks. I actually just found out it was 8 Guage... I always thought it
was 10. But I did buy some more 8 guage to rewire the road gear amp and it
appears to be MUCH better than before, but its still cutting out... I'm
going to try like u said and shorten the power wire. I'm not the one that
ran the power wire, so there could be lots of extra lying around.. Im going
to shorten it where i can.
