[QUOTE="Lasherž, post: 8703770, member: 679555"] That post must have been deleted. AGMs are much better for car audio, but the RPM drop isn't normal and it's pretty common on his vehicle. That will likely solve all of his other issues without buying a 250 dollar battery plus make his car run better. You expect some drop from an alternator, but this is a 2015 vehicle, not 1990. Modern ECUs adjust readily to handle loads by increasing idle when it needs to and with very little delay, old cars had higher idles that didn't adjust and so you'd see drops like that all the time.
