How o get my factory car speakers to play thru my amp with my phone hooked straight to the amp

Probably just need to insert a preamp in between them
or just connect the phone to the head unit via BT, BT adapter, or Aux input

A few of my friends use this on their HU's that don't have BT but do have Aux input jacks.
