This was a budget build so dont hate on it just looking for some opinions, as I stated in the description Im kinda new to car audio

Right now this is my setup:

Alpine CDE-121 deck

JL Audio TR525-CXi back speakers

Kicker KS525 front speakers


Sound Ordnance M-2250 amp

Sound Ordnance™ B-24 subs

At the time I couldnt afford a amp for my speakers so right now its bein powered by the deck. How much of a better sound will I get if I buy an amp to wire the front and back speakers? Will I need to get a capacitor or extra batteries?
Iso some help thanks guys

there is little to no point in amping them with your current setup.

the main reason to amp mids/highs is because your lows are overpowering them....i can't see this being an issue with that sub/amp setup

you will NEVER NEED more batteries or a capacitor for a daily use setup...relying on a battery just means you will be broke down somewhere needing to get a jump start because your battery is dead.

you upgrade the alternator if you need more power...not add more batteries or capacitors.

What are the three big upgrades?

its a wiring upgrade where you replace your main electrical system wiring with larger gauge wiring. the alternator to battery +, battery - to body ground, engine to body ground are the wires you replace.
