Speakers noticeably quieter after battery died

[MCfRed619]

I have a 2016 Journey R/T that came with Alpine speakers. Recently my battery died so badly that it couldn’t jump start and had to get towed. After my mechanic recent all the electrical I noticed all my settings were reset. Normal and fine, I set the speakers back to the heavy bass I had it at. But now it’s noticeably quieter, my rear mirror doesn’t even shake anymore. Is it even possible that something went wrong when my battery took a dump? And how do I fix this, half the reason I still have this car was bc I loved the speakers so much. Should I go back to a mechanic or get something tested at an audio place (dealership isn’t an option). Any suggestion is VERY much appreciated, thank you.

Do you have the stock Dodge radio?

 

What aftermarket equipment do you have?

I haven’t added anything to the vehicle but it did have one owner before me. I’m pretty positive it’s just the upgraded package with Alpine speakers from factory

I guess. I just know the mirror would shake during certain songs and it just doesn’t do that anymore. My bass has always been set to +9 too.

Running battery dead on a lot of cars seems to create a few weird issues sometimes. Easiest thing to try is pulling main power for a few mins and see if that corrects anything. The sound system has a large rear amp with a separate sub power supply. Think mirror shaker module. It's even possible there is a blown fuse somewhere.

 

If you have a multi meter and no how to use it. Start inspecting and testing continuity on fuses in passenger kick panel. Electrical specialist shops always better than mechanics for fixing and troubleshooting this type of thing.  Even though alternator and battery swaps are typical mechanic repairs. Our journey has the alpine system, if you crank it there is decent power. Sub woofer is important part of it.

The fuses to check are on the interior fuse box.

 

Located below and to the right of the glove box.

 

F128 radio

F126 audio amplifier 

 

If okay. Try resetting them both by removing the fuses. Wait then reinstall.

From the ppl I’ve talked to, they’ve mentioned fuses too. Thank you for the location! I will be trying this very soon

Fuses are my next step. I’ll try resetting  first then new fuses. Keep everyone updated. Thank you for your knowledge.
