Hi all! It's been a while since I built my own system for a vehicle but I recently got a 2021 Tacoma double cab non-jbl and would like to upgrade the audio system but keep the head unit. I've seen a lot of people speak highly of the OEM Audio Plus system but I feel like it's kinda mostly marketing as most of them are youtubers. I want to build a system for around $2000-$2500. Been looking at other alternatives like the Infinity Kappa 90csx for the front doors and dash and the Infinity Kappa 62ix for the rear doors and a couple JL Audio 10" or 12" TW3 subs. For processing I've been looking at the JL Audio Fix 86 and not quite sure yet to do on amplification. I really would like to know if anyone has any experience with the OEM Audio and if it's something that actually is comparable to a nice custom system for roughly the same money.
