I installed the CDT Speakers yesterday (
https://www.cdtaudio.com/2ohm/subwoofers-2ohm/cl69s2.php. ) and did some sound dampening.
No issues with ANC. I checked the polarity of the stock speakers and matched it with the new speakers , interestingly enough all my stock speakers were in + phase ( outward movement of cone) , which contradicted what speaker pop app said.
This is what I used , got it on amazon. Made it very simple and took out the guess work. I wanted to make absolutely sure I was hooking it up correctly.

Overall , I am pleased. Sounds has improved in quality , not much louder if any (didn’t expect for it to be since it’s still on the stock amp ). It did improve bass some ... but not enough for me , I’ll be adding some subs later.
