Thinking of doing a upgrade. Need some opinions.

For the past 5 years I've been running 2 L5 12'a on a Kicker ZX1000.1and I think I'm ready for something new. I've had my eye on a single 12W7 for some time now

QUESTIONS 1.Is my current amp suitable for a single 12w7. 2. How would it sounds compared to my L5's 3. Any other recommendations on a single 12 for my zx100.1

THANK
