Tundra after market alternator

Hi I’m running a big 3 upgrade, 1 lead 12v north star battery and ofc 0 gauge wire all around with a capacitor and I’m still having issues with my alternator going from 14-10.2 and the truck is hesitant when starting up , I was wondering if there was a good after market alternator that’s on the market due too the fact that I’ve used most the upgrades I can besides the alternator, I’m running a taramp 3k HD@ 4 ohms , DS-18 frx 3.5 @2ohms , 8 8” ds-18 pro gm-8mid range , 3 quantum audio 3k 8” subs

 

There is a high amp output available. Can't remember the brand, do a search with the search box or w8 and others will chime in. I think you should do a second battery tray, check SDHQ site.

@Cruzer is working on, or might have it installed at this point, a 300 amp alternator. https://www.tundras.com/threads/cruzers-re-build-for-the-rubicon.79505/page-23#post-2688921

 

Why not just install a capacitor?
