I've got a buddy with 3 evils in a wall in his Camry on 12k watts... made me an evil believer!! Lol. I love that they're made by FI, how long have they been around now? 15 years?
As fas as my build goes, I've got a quad cab dodge 3500 that I'm gonna put it in. Taking out one of the rear seats on the driver side, 4th order bolted to the ground with the port pointing towards the back of my head. Upgraded 6x9s in the doors and running a zapco 4 channel 400 watt BLuetooth. Just ordered a 300amp Ohio gen alternator so that should be here by the end of the week. Still need to do my big 3. And I've got a 22ah limited lithium battery im going to be putting in the storage compartment underneath the remaining flip up bench seat in the back along with a dry cell under the hood so I should have good electrical.
