Battery/Big 3/Alternator/Usually at least 4ga wire
Avoid capacitors unless you already have a massive electrical....

What size wire did you use for your big 3?
Most cars come factory with at least 8ga

yeah man 8 guage is not letting the power travel fast enough, gotta run at least 4 guage, preferrably some 1/0 kicker hyperflex (thats what I like to use). Any brand that uses over 4500 strands with their 1/0 wire.
That's if you want optimal voltage...with what you have besides adding to your electrical (extra batts, upgraded alt, etc.)

Use 4AWG, 2AWG or 1/0AWG.

what amp do you have? that would determine wire size, if it is only a little amp 8 might be fine. what is the voltage at the alternator at idle?
if all else fails after everything... get a mla!

Bigger wire for the big 3, 8 is kinda small, I'll do 0g. Also what front battery do you have.

I have an RD 1750.1 for the amp, and an Alpine PDX 4.100 for the speakers. I could run 1/0 gauge, would a battery upgrade be worth it?
Try the wire first. Just use 1/0 or 2/0 welding cable. If voltage is still bad then add an alt or batts (2 group34). If one doesn't work then do the other. Your big3 should be in at least 1/0.
Most of your drop is from the wire from + batt to the amp. If you are running 8ga to that amp then i'm not surprised you are getting a 0.8+v drop to the amp. 1/0 should make it less than .1.
