A/B class vs. D-class?

[gloryaccordy]

I have a 900W A/B class Alpine amp, and while it hits hard, my friend has a Hifonics 1500W amp he's getting rid of, and I was wondering if it would be better to go with the Hifonics amp. I personally like the Hifonics amp, and I think it makes cleaner power...the Alpine has bandpass control though.

Also, what do you guys think of sealed boxes vs. ported boxes? I have a sealed box now, and it hits hard and has a nice linear response, but my friends all have ported boxes, and they have that deep, tuned, loose sound. What do you guys think?

ported box sealed in with great stuff is probaly the best set up for SP

Get the Hifonics amp. You won't be sorry!

I say get the hifonics, sell yr alpine and get a 2 or 4 channel for yr doors. Sealed usually sounds cleaner (tighter) but needs more power to get loud like ported. I like 2 sealed 12's for the cb7. What kind of music do you listen to most?
