Alright...got my speakers a couple of days ago and install took me only around 30 minutes including a modification to the speaker adaptors. The sound is awesome compared to stock and the bass...woa!! So tight and deep!! I love it!!! But here's the problem...when I listen to some songs, at lower volume (10 to 15), the sound is clear is a bell and bass is great (Bass +6, Treble +6), but when I crank it up (at least 15), there's this crackling noise at each beat at the peak...sounds as if it's distorting. I actually had to turn the treble down in order to listen to the song loud. Is that a problem?
