Plz help! 2007 double cab JBL system upgrade. Anyone have a speaker diagram wiring diagram?

My Yota fam, Y’all are so knowledgeable. would lo love a Quick response. I have Component focals with passive crossovers. My door panels are off, new Woofer is in the door and Tweeter in the sail. I made the existing leads from the woofer my input to the crossover. Then I fed a new wire to the woofer and another wire from crossover to sail and tied The existing tweeter leads with the crossover wire and speaker. Did I get my input wire wrong? Anyway, I can’t find a specific wire diagram for my 2007 double cab w jbl. I plan on replacing stock amp with a four channel amp. I also have a 10” JL sub I’m in the process of installing. I’m building an enclosed box to put in the back where I removed the seats. My plan for wiring is either to make the crossovers 2 channels and bridge the other two for the sub, and power the back two speakers off My Aftermarket head unit. my other option is two install another mono amp for the sub. This is the first system I’ve ever put together and I’m doing my research after the fact. Sounds like I should’ve got an amp with DSP and I also need to purchase a base Knob. Can I just buy some generic one and plug it into my RCA jacks? Any help would be much appreciated, you have no idea!
