[Filip ON4AEO]

Hi everyone I'm new here have a Dodge ram 1500 larami year 2012 with alpine sound. I install an aftermarket radio with carplay. but can't find the connection diagram anywhere to connect the amplifier from (pre amp out of radio 4 channels plus woofer) to the input of the amplifier, which makes an output of 9 channels. Is there anyone who can help me?
Thank you in advance
Filip
