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.
