Just seeing if anyone just upgraded their speakers while using the stock components. I know that Infinity Kappa 60.11cs have fairly large magnet. Curious if anyone have done a test run or with something similar. I was going to stick to component upgrade since I have a feeling if I put 2 ways in the front door is going to get a bit tremble-ly. Though in the end I probably look into which amps I can load into the system without killing the functionality of stock system.
