My tweeter on my driver side door is crackling really badly so I'm looking to replace it. I'm just wondering about the whole 2 ohm 4 ohm thing(I have the bose amp with an aftermarket kenwood head unit) if I get 4ohm tweeters as long as they are a decent pair will they get blown very easily or just sound output will be degraded? These are the ones I'm looking at, and if I go with 2 ohm I found these Infinity Kappa 10.9t anyone heard of them they have some extra crossover block to hook up with them I'm concerned about clearance and installation.

Polk db1001 4ohm set

 

JBL GTO18T

found these 2 ohm pair as well look pretty good and small
