09 silverado options

[stevemead08 752]

I have an 09 silverado crewcab v8 thats about to go form 3k to 6k so i think its time to upgrade the charging system.

DC has so many options im a little lost. i currently have my factory battery and a deka 9a31, going to add another group 31 in the back with the amp.

how much alternator do i need with 2 group 31s and a large OEM starting batt?

On your truck with that much power, run duals for sure.. I'm going to trim some of the options off the website soon, we have WAY too many options for people.. We build so many different types of alternators that it actually hurts us more than helps us... My recommendation, leave the stock alt alone on the stock battery, and run the secondary to the system. You can also run your mid-high amps off the stock system if you want, and keep the sub amps separated, or run them all together. The problem on your truck is running an RVC (PCM Controlled) alt in the factory, and a normal 4 pin in the secondary location, they just dont play well together.. IF you dont want to run a dual (which I would highly recommend) we have our heavy-hitter alternators coming.. The new monster I'm building will do 330-340 and well over 200 at idle (think 230-240~ish) and with a couple of batteries it would run 6K no problem. Really, it just depends on your budget and what you want to spend. You have one of those systems where one 300+ amp alt wont power it along with the truck's loads, but, you can run a dual kit with a smaller alt for about equal money to what a single premium H.O. alt will cost you, but with a dual your doubling power for equal or less money, and dual's win this battle hands down... If you need more info or more help though, dont be afraid to call or post up here and I'll help you out any way I can.. Rob

I think id like to run a dual alt set up using my factory alt for my truck and the second alt for my mono amps. what all would i need to complete this installation.

Budget is not a big deal. if i cant afford it now ill save up and get it soon.
