Dafaseles Posted May 5, 2021 Report Share Posted May 5, 2021 Yeah dude, those SFB amps are beasts. You gotta feed the beast. I feel like doing the big 3, at least 270 amps of alternator (more is always better, you can't have too much electrical) and 2 80 ah (or more) AGM batteries should scrape you by. Or, if you're willing to do a battery delete, 1 lithium and 270 amp alternator should suffice. 2011 Chevy Silverado under construction My build log here. Check it out!

Kyblack76 Posted May 9, 2021 Report Share Posted May 9, 2021 Wired at what nominal load? Id bet a second battery would be more than fine, with some up graded wiring. If your just doing music, not burping, wired down, youll be ok, adding a second battery is all. No need for 11 alternators for what, 1800 watts. (on music), and yes i know, it says it does 3k at 1ohm, but unless your wiring down to like 1/4 ohm, and doing burps, youll be ok, Music is dynamic, you wont see anywhere near full output, or load. Edit- replace your oem battery with a nice stout one, with (obviously) needed wire. Play it, watch your voltage, add a battery IF needed. Bet you may not even need that. Cheers.
