Apple CarPlay Siri voice is too loud after amp install- help

All,

Last week I had 2 Alpine amps installed in my 2020 TRD OR, LB, non JBL.

Alpine 4 channel amp front and rear - mono for sub.

Even with the OEM non JBL head unit turned down to zero, damn Siri is way too loud.

Setting on my phone were no help.

Any suggestions on lowering the Siri volume?

 

That crap was always too loud in mine without an amp. Lol. It’s a setting called “voice” or some crap like that. I want to say it’s under Phone settings. Could be mistaken on the location, but I know it’s the “Voice” setting.

Almost crapped my pants the first time Siri yelled at me
