In my car system using the same track I can hear more top end extension, and I guess I could chalk it up to the speaker’s frequency response or just the gains I have set for the fronts at the amp.@213runnin
Are your tweeters damaged? They are very easy to damage if you overload the amplifier! If they have removable grills or if you know where the tweeters are, run the system, put your ear to the tweeters and see if they are even working. If you have clipped the amplifier at any time in the past, it would only take a second or two to fry the tweeters. This would explain a lot...
