I am currently installing in a 2008 Escalade, and know I need an upgrade on the electrical system - this isn't a "do I need to" thread"; what I am look to have answered is which option will work best or if there is a difference
I am installing the following:
1 X Kicker 650.4 (Components)
1 X Kicker 2500.1 (Subs - 2 X 12" @ 4 OHM)
2 X New Batteries (no idea what brand ot type, the factory one year old AC Delco battery doesnt start at -20C and colder - 615CCA isnt enough)
Big 3 (@ 0 GA) on dual batteries
All cabling (Big 3, Amps, Grounds) all 0 GA
Now, I know I will need an alternator upgrade, the real question is single or dual.
If I run a single 300A DCPower unit, I would run the batteries in parallel, with no isolator and then the drain would be on both batteries for the system on big hits "IF" there was more draw than the alternator coud supply. The benefit to this is at start up there would be more available amperage and less voltage loss - dumbed down, basic theory - this isnt the issue.
Option 2 would be to buy a dual alternator kit from DCPower, adding a second facotry alternator. This would allow me to completely separate the audio system form the rest of the vehicle. Deck and amps would all run off of the second battery/alternator with no tie in to the factory running system.
In either option, will there be enough power to run the system? would one system be preferred over another, if so is there a particular reason?
