One of mine are blown.....I disconnected it for now. Less bass, but it is much clearer until I get a replacement. Maybe I will check out JBL GTO series........are there any differences in model's if I were to use them for our cars(three different 6X9's that I found) I understand that they may have different tweeters, but that doesn't matter as they are only used for bass in our cars(as far as I know) Thanks..........opinions on these speakers please or on others that I should replace them with in the factory locations/sizes.
