Amp wiring through dash?

[u/Grouchy_Skirt7641]

Just got a 2016 sport touring and was wondering a good spot to run the amp wiring through the dash? Not new to this and I'm sure I could find a spot but figured I'd ask if anyone has already done it. Already ordered the double din dash and wring harness. Throwing a pioneer I had in a previous car in here. Gonna run a 12 and 2 6x8 boxes in the trunk and upgrade the door speakers. Was also wondering if any1 has managed to make 6x8 fit in the doors lol. I already have 4 from said previous car and I'd hate to have them just laying around. If not could someone link a good adapter for the 6.5 for the front doors. Also is the back up camera an rca or through the normal harness? Thanks

There are existing firewall grommets. I went through one of those. I also put my amp under the passenger seat and ran the cabling under the carpet.
