Crossover is made of some capacitors,UPDATE: Good News!
A little backstory. I realized after connecting the harness (ver. A) that the door tweeter and rear-passenger right shelf speaker were noticeably louder. I knew and had a hunch that there was something off.
I ordered a $13 polarity tester at Amazon. I tested all speakers and I was right on the money. The polarity are reversed on both door tweeters and passenger rear-right shelf speaker. I reversed the wirings and when I powered it up to test. The Door woofers came back to life. Right away I could feel the thump. Everything is sorted out now but Hansshow need to do a better job making their harness. Reversed polarity, left and right channel are reversed.
My system is now complete. You can't even tell I have a subwoofer because everything are in sync now. Before reversing the polarity on the tweeters. All of the mids and bass were coming from the trunk. Now, the bass is inside the cabin and not at back.
I have a question. I see the DIY has a box module. I'm assuming it's a crossover? My Ver. A harness doesn't have it. It seems like the door and pillar speakers are tapped in the door woofer. Wouldn't this kill the tweeter without using any crossover?
We integrated it into the wiring harness for the version series.
