I have a 2015 Silverado 2500 with a beefed up power system (at least I thought).
My Voltage starts at ~14.7V and when I bump it gets all they way down to ~12.4.
YES it recovers pretty good.. but I shouldn't be breaking under 13V PERIOD !
What's your thoughts here...? I'll list the basic components of my setup...below:
(I can provide a detailed schematic if needed).
1. 320 AMP Iraggi Alternator w/Big 3 (Actually Big 4). ALL GROUNDS CHECK 3x
2. 4000W RMS Memphis Amp (Running at 2000 W RMS at 2 Ohms)
3. ~500W RMS Memphis Mojo Amp (Running Mids/Highs).
4. 1 Memphis Mojo 12'' 1500 RMS 3000 Max
5. 2 (Yes Two) Yellowtop Optima AGM D34/78 (750 CCA 55Ah = 110Ah).
6. ALL WIRES are GP Audio 0 Gauge wires.
I checked for clipping and I'm not clipping. I have the GAINS on the 4k Amp ALL THE WAY DOWN. Overall everything sounds ok, I just get such a large voltage drop and EASILY.
The only thing I can think is that I need to increase the (aH) by adding an additional battery. OR Maybe I'm having a PCM issue (with these newer vehicles) the PCM Module | US Alternators PCM http://www.usalternators.com/gm-pcm/ may be my resolution?
The PROBLEM is that the alternator should not even remotely struggle or have to even use the batteries period. Especially since I have my gains all the way down. (I checked 1x with a Clamp Meter and when at ~12.6V it was outputting 16-40A Max.) (Aka not struggling etc).
PLEASE HELP !!
