I am working on adding tweeters and wrestling with determining the proper capacitor I need to protect the new tweeters. Also just the act of adding a 2nd tweeter in parallel would lower the impedance from 4ohm to 2ohm, thereby changing the crossover point on the stock boss tweeter. So don't we need to change the stock capacitor to avoid tweeter damage?

If I had some plain regular ol' resistors in front of me. And I wire a couple of them in parallel, does the color bands on them magically change? Each resistor individually hasn't changed in value.
