Installed amp/sub and now rough engine, bad mpg
Recently had my 2018 SXT installed with 1600 max watt dual kicker subs with 2400w amp. After leaving the install place, I noticed sluggish acceleration, a significant vibration in break peddle when putting on brights, and MPG is markedly lower.
I don’t think weight is an issues, given the fact all the equipment was in trunk for over a week and no issue. I pulled fuse 29 to reset tranny and still the problem.
Is this something to do with the alternator? I don’t want the bass to hurt my baby, is there an easy fix to this?
