Spazy808 Posted May 14, 2020 Report Share Posted May 14, 2020 If I run a skar rp-2000.1 a 4-500watt four channel and a extra battery off a 100amp alternator. Or will this just be bad and a h/o alt would be the only option along with a second battery Link to comment Share on other sites More sharing options...

It's possible even to find an alternator shop in your area and a lot of times they can rebuild your alternator to up the output 2011 Chevy Silverado under construction My build log here.

12V71 Posted May 14, 2020 Report Share Posted May 14, 2020 There are so many misconceptions about DC electrical systems and how accessories effect them, this will apply to anything. 1. What is the needed running amperage for basic operation of my vehicle? Ex. (Draws the Most) Modern, electronic ignition with multiple coils and electronic control modules Ex. (Uses the Least) Diesel with straight drive and mechanical injection no abs 2. What accessories does my vehicle use in basic operation? Example does it always have the lights on day and night Is there automatic ride control 3. how many accessories are you using Do you run the climate control (heat A/C) all the time what else has a constant draw GPS, phone, etc. _______ amps= total amount needed for basic operation above amps x 25%=_______amps needed to properly maintain battery +or- depending on how long you operate the vehicle (normal time driving) between restarting. Now what are you installing? maximum current draw? ____________amps @ 75% _________amps @ 50% _________amps @25%___________amps How do you listen to your system and how long at each % ? Are you planning on competition? What is the condition of the battery and alternator? (these are questions to ask yourself and find out what is needed for the results you want) Link to comment Share on other sites More sharing options...
Spazy808 Posted May 14, 2020 Author Report Share Posted May 14, 2020 Well I’m no math guy so that stuff is a bit confusing to me sadly. But I’m not gonna be doing comps just my daily driver but I like to Slam what ever I got. The truck is super basic no power locks windows headlights can be turned off during the day run the heater once in a while during the winter it’s Oregon so not horrible so I’m assuming it doesn’t use much to begin with Link to comment Share on other sites More sharing options...
