Lmk if anyone finds any errors...
Ahh okay that makes more sense. From + & - on the amp -> + gets jumped from the 2-pin to the 3-pin and negative jumped from the 2-pin to the 3-pin -> + goes to the diplexer -> splits the + signal to the tweeter -> each + signal goes through filters and out to each speaker. I think I'm reading it right lol...

I think your impedance would be higher than stock setup, which means less power but better quality audio. But if you go with the aftermarket crossover (like I'm looking into now) the wiring will be simplified.... + & - from amp -> goes to input on crossover unit -> splits the signal to the midrange and tweeters (parallel wiring). I want to do some testing though to be sure these will work good for a stock system
