New Battery- 2 12's hit at minimum. Help

[Jaheny]

Normally I have somebody do installation for me, but I am wondering if there is something I can do myself, to fix my issue?!?!?
2018 Mitsubishi Outlander Sport LE. I got my battery replaced and my subs are weeeeeeak. I'm not tooooo electrical savvy because I get paranoid . Any suggestions? Thanks in advance!

HU settings ? Lol

Sounds like your settings reset

HU settings ? Lol

I fiddled with that but I can't find anything to change. Nothing on the hu is different than it was before the new battery

A natural assumption, but nothing on my hu has reset, my settings are still the same

Is the new battery the same capacity as the old one?

Where is the battery located ?

Changing a battery shouldnt have any effects on the subs ..unless deck settings changed ...and level is down...they are newer electronic amps like some Alpines the MRD series comes to mind and their settings were reset ....or they crossed wires hooking up a battery accidently and fried somethingbin the amp ...it doesnt take but 1 sec ...couldve dropped a wrench across battery terminals

Welp, I'm learning things with these questions fr. lol, I have absolutely no idea on that. I suppose it may be best to take it somewhere to get it checked out

check the power wire connection at the battery.better yet,lets see some pics of the battery connection and amp connections.that is why we put a fuse at the power wire at the battery if one is not already there.
