Stupid Stupid Voltage Drop Question...

[JustStoppingBy 10+ year member]

Ok..

I have a steady 14 volts at idle at the back of the truck running a 1 Farad Cap...

Running (1) Kenwood 850 RMS, 1500 peak Class D

(1) Power Ak 800 watt Peak 4 channel

(1) 400 watt power inverter

Commercial Type 31 bigass front battery... HID conversion (1/2 the draw of the halogens) and 2 smaller 50 watt Fog lights...

Im dropping down to 11 volts when the bass hits low.. and its throwing the amp into protect... Ive done the BIG 3 with 2 gauge welding wire and also redid allll of my grounds, and connections.. The headlights don't dim since they are HIDs but all my DASH LIGHTS dim like hell...

Should I look at

1) 2nd battery

2) larger cap

3) I die in a fire?

Your amp grounds and +12v connections are also 2 guage? Maybe try it without the cap.

Yeah, might need a bigger alt, or maybe that one isn't putting out what it should.
