Joshoe Posted May 25, 2014 Report Share Posted May 25, 2014 Hello everyone heres the rundown... I have a 2013 GMC sierra with a the Duramax diesel.. The configuration that it came in has two batteries and altenators that cam STOCK. Altenators are 150 amps. I am trying to figure out do I need to do the big 3 twice? Only once to the battery im connecting to? I am also installing an extra battery in my cab for my system. What type of wiring configuration would be reccomended? Just connect the rear battery to front battery? Connect it in series or parallel to both batteries? Thanks Link to comment Share on other sites More sharing options...
Broke_Audio_Addict Posted May 25, 2014 Report Share Posted May 25, 2014 I would do runs to each battery from the alts then a run from battery to battery then all your grounds for each battery just like you would do for the big three but twice because you have double everything under the hood. You would be connecting them In parallel. The amount of power you plan on running will determine the amount of runs you will need to do. That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.

Maybe morea than a little!So with that said.. I understand know about the big 3 for my vehicle. But when you say to run the batteries parallel your talking about my battery that would be in my cab? (Just want to make sure).. As far as runs go.. I have yet to decide on an amplifier either a SAZ-2500 or 3500 and havent even bought the batt yet so I know whats my limitations on the supply of my power to my amplifiers Link to comment Share on other sites More sharing options...
Joshoe Posted May 25, 2014 Author Report Share Posted May 25, 2014 So for the runs all considering my decisions would that depend on the size of the amp or rear batt? Is there a rule of thumb regarding runs? Could I even use bigger wire to reduce the amount of runs? Link to comment Share on other sites More sharing options...

Yes you could use larger wire to cut down on runs. What amps are you planning to run?

MECHMAN Posted May 28, 2014 Report Share Posted May 28, 2014 Just don't mix battery types (ie AGM, Flooded) Keep the battery types the same. 1-888-MECHMAN www.Mechman.com [email protected] Link to comment Share on other sites More sharing options...

Yes you could use larger wire to cut down on runs. What amps are you planning to run? Probably a Sundown Saz-2500v.2 or Sundown Saz-3500v.2. along with a Rockford 400.4 (for now..) with possibility of one more 4 or 2 channel in the rear stage. The runs would go from my extra batt INSIDE the cab of my vehicle correct? Link to comment Share on other sites More sharing options...

So does this mean the extra battery inside my truck that im installing to run my amps. Should match the ones that currently run my truck? ( because those im guessing are not AGM just regular batteries). Link to comment Share on other sites More sharing options...
CommGuru Posted May 28, 2014 Report Share Posted May 28, 2014 This applies to every battery in the circuit. All batteries that are connected to each other in any way need to be the same type. Oh, and pics! Sounds like a nice truck. Good luck on the install. Link to comment Share on other sites More sharing options...
