Will upgrading my electrical up the output noticeably?

Just as the title says....

I have a stock 105 amp alternator, Duralast gold battery, and stock wiring for it all. Nothing special, I know, but I plan on upgrading all of that (300a alternator, 1/0 gauge wiring, extra battery for just the audio).

When my music is playing my voltage drops to 12 volts, and sometimes lower. My brutus is rated at 1500w @ 14.4v. If I upgrade my elec. system to where it stays at a constant 13.8-14.4v, will there be a noticeable difference in output?

Sure, you're losing output because of voltage drop. If you stabilize your electrical system, you'll gain some of it back, but it might not be noticeable unless you're getting metered on a daily basis. Now, if your alternator is struggling to keep up with the load, and you're getting severe light dimming, you might look into a higher current alternator...

Yeah basically I'm asking if there would be a noticeable difference to my ears.

Doubtful.

There was when I upgraded by big three. I gained noticable spl from my sub.
