Will replacing stock battery with a better battery on stock electrical help much?

YES- an XS power D3400 would be a huge improvement. Also, upgrade the alternator cables if you havn't already. We have a nice kit for $29.

No need really to upgrade the alternator at your wattage.

Thank you Mechman(and everyone else) for answering my question, and the alternator cables are 4 gauge, so being the fact my alt is 100 amps at most, big 3 wouldn't do much, but thank you for the offer.

The new alternator is for future plans, where I end up quadrupling my power, but that's gonna be a while.

I'd still recommend doing the big 3 in 1/0 at the same time you replace the battery.

CURRENT SYSTEM:

  • Alternator:
    1. Stock alt on mids/highs
    2. Isolated DC Power 270 SP - Charging @ 16.8v
  • Batteries: (2) XS D1400s
  • Power Cable: Double Runs of 1/0 KNU Kolossus Fleks
  • Headunit: 80-PRS
  • Sub Amp: DC 5.0k
  • Subwoofers: 2 RE MT 15s /PSI dual .7ohm recones
  • Subwoofer Enclosure: 9.1cubes @ 32hz - brutal.
  • Mids & Highs Amp: CT125.4
  • Active Components:
    • Mids RE XXX 6.5c
    • Highs - 3 RE XXX tweeters per side(A pillar)
  • Noise Control: Damplifier Pro all over the cab.

Big 3 will make a difference. In your case maybe not a whole lot, but when you upgrade your alternator later which you are planning to do, it will already be there for you. Upgraded grounds will be the biggest difference for you if you don't already have a negative from from your amp directly to the battery!

I have an XS D3400, great battery for the money, I'd recommend it to anyone!

*New vehicle and system coming soon.*

Grounds are the frame of the car, added a copper bar in between the frame, and ground wire. Noticed little less voltage drops at time and slightly greater output, so ground's fine. Actually thought about using the battery's ground as a ground.

Yeah, it's probably my battery, I'll just go looking into getting an XS D3400, and see if that helps. My group 47 lead acid probably wasn't built for audio anyways, think it's too small.
