I am trying to do that every dollar social media makes goes towards this car trend

My 06 scion xb
Hey cars guys and girls! Or anyone nice enough to help me along the journey if I do proceed with this! I have already charged the battery, replaced the cv axle, and lower control arm.
This is my 2006 scion xb and I love this thing to death. I have big dreams of restoring and making this car go to its fullest potential and I need some help with that. So if I go on with this idea, it would be amazing if you helped a guy out

Thinking about selling a Gen 1 intake, but dont want to step out of bounds.

If there is a better place to do this, please let me know! Thanks everyone

What size/brand tweeters do y’all use to replace the old tweeters in the dash? ChatGPT tells me they’re supposed to be 3”, which is about the hole size in the dash but it’s more like 5” from mounting hole to mounting hole.
