Extra power necessary?

[ilovehoes2]

Hey what's up people! I'm adding a jl audio stealthbox to the factory system (2019 midnight edition). It's only 300 watts. Is this gonna require a "big 3" upgrade or better yet, what would be some recommendations y'all would suggest for this setup in regards to not burning up my battery or alternator? It's been forever since I've messed with anything sound related and I'm passed the days of my lights dimming every time the bass hits . Anyway here's the info:

300 additional watts is easily handled by your existing electrical system. Just wire your power wire to the amp directly to your battery with an appropriate power block and gauge of wire (#10 gauge should be plenty). It certainly won't hurt if you do the big 3 upgrade, but it is not necessary in your case.

I'm running 800 watts out of 2 amps, and I did not make any modifications to my truck's electrical system.
