My Amp Meter is not an in-dash pass through. I have a 100 amp shunt and a panel meter to monitor. The Shunt is connected between the alternator and 70amp fuse input to the fuse box.
...Do a search, find the other thread where we were talking about this.
My method, giving up some efficiencies, is to use a deep cycle battery, to an inverter, to a charger to the house battery, and kill the alternator field/ or use a Normally Closed selenoid or relay to disconnect the charge line to the alternator.
The reason for this inverter/charger setup --- mantains proper 13.8 voltage to the car. And 2..... I have yet to find a DC-DC converter that can do 12v-13.8 40amps (not for less than $50 anyway)
.... if you will notice, not many here have large stereos.. THEY WEIGH TOO MUCH!
