Thank you for the frank reply. That’s exactly the type of information I find useful. To clarify, I'm not wanting "louder", simply better SQ. seeing how I will have to buy something to drive them; I want better than I have now, not the same or worse. Make sense? For example, the stereo in my truck. My subs are rated at 500 wpc 4ohm ea. the first amp I had was 1000 watts. I replaced it with a 1500 wpc amp and they sounded completely different. Tighter, fuller and just plain better. Not any louder, just better.
