hmm.. yah i knew i was undepowering them, but i didnt know that it would make such a drastic change. I had a 15" RE SE before this BTL and was running a power acoustik amp at 800w and that thing hit exceptionally well. Alot louder then my current set up. So big 3 and a more powerful amp is whut i need to do huh....Can any of yall suggest an amp thats not too pricey, but will make my roof flex? I jus got my amp yesterday, i might have to sell it already, hah.
