dylanh02 Posted November 5, 2021 Report Share Posted November 5, 2021 I am going to be installing a full system in my 2015 F150 XL 2.7L. Everything is stock including electrical, I was wondering if anyone could help me out with the electrical side of this install. I am curious as to if my stock alternator can handle around 2.5k watts, give or take, without any serious voltage drops or clipping in the amplifier. I’m not sure what amp I am going to get yet but I am planning on installing 2 12” Skar EVLs which are around 1200 rms, along with a 450.4 amplifier for my door speakers. Will my stock alternator be able to handle this power? Of course i’d also be installing an AGM battery. Link to comment Share on other sites More sharing options...

Dafaseles Posted November 5, 2021 Report Share Posted November 5, 2021 It really depends on what your alternator is rated at. I think 2500 might be pushing it a little as far as a stock electrical on a V6, although, being a dual turbo engine, the high revs might work on your favor. Does your truck have start/ stop? Also, another thing to look at is the charging system and how it works. If I'm not mistaken, those trucks have a voltage sensor in the negative terminal on the battery. I've heard horror stories about upgrading electrical in this trucks. But most have to do with upgrading the alternator. Lastly, to get the absolute most out of your stock system, do the big 3/4 upgrade with some quality OFC cable for maximum current flow. I've also read stories about people having huge problems getting a good ground on the aluminum bodies. If that's the case with you, I've read people just grounding straight to the battery has helped. 2011 Chevy Silverado under construction My build log here. Check it out!
