Battery voltage drops in manual mode
So ive been noticing my voltage dropping in manual mode. I had my alternator checked out and it is running fine. So I figured it was the battery so I just changed it yesterday. Bought a brand new bosch agm and had it installed monday. I drove the car this am and it happened again. It has happened with the old and new battery. At first I thought it was my after market stereo. So I decided to drive in Manual with the stereo off.
When I push the car hard in manual I see the volts drop. But when I put the car back in auto grandma mode the voltage rises back up.
ANy Ideas?
Thanks

Last week the voltage dropped all the way to the last mark and my dash board lights went nuts and stereo went wonky. I had to turn off the stereo and drive real slow

You should try unplugging the rem wire out of your amp/amps so they don't turn on the amp and redo your test. It may be related to where they/you tapped in to get your remote wire signal from.
How long have you had the system in?

It could be belt slipping maybe . High demand of dc at high rpm and belt slipping so the alternator cant keep up. And you don't see it in auto mode because you don't push the car let's say beyond 4000rpm.
