I'd like to see a HCCA275G4 make over 1500 real watts, and not for a nanosecond. In fact I'd have to see it to believe it. Forget it on a first gen. Never going to happen.
I'd also like to see one handle 24v input. Man they used to change color at 12-14v, they must fricking glow at 18+
Finally, low impedance, HCCA, and clean can never be used in the same sentence. low impedance, HCCA, and arc welder maybe...
Don't get me wrong, the HCCA amps are classic badass car audio history. Let's just keep reality in mind.

maybe 2100hcca17.7v yes 18 volts. an no never changes color
you like new class D? it's nice for low quality crap, but I'd rather have a/b and cleaner sound anyday than some new rockford class D that just starts on fire, BOTH of them. haha
anyways this thread is now void of it's purpose

you guys are nuts haha orion was under rated sure, but how does 2x75 turn into 1600 lol i have a 225 hcca a punch 45hd and as there both old school neither are super heros c'mon...most of the amps back then were very good performers but keep it real.

except my says it, yours is a half baked equation.

The HCCA "R" generation were notoriously weaker in power. They all could do rated power but they failed to meet the underrated power of their predecessor's.
A first gen HCCA would get so hot at lowest recommended impedence that they would turn pink.
Not sure why some of you are doubting that a 275G4 is capable of 1600rms bridged at 1ohm. Spec is 1200rms and that is at 12v. Bring up the voltage to 14v and it doesn't need to be too underrated to achieve a 1600w figure.
The new RF Power series of amps are some of the best performers available today. I'll take one over many of the "oldschool" products.

About a month ago my trusty 551X just burned up after being installed for 2 years, when I opened it up there was a hole about 1.5" on the output side of the amp.
Those were awesome amps, but I don't know if I'd use them again...

It's what is on the board that counts. A HCCA225r won't do near the power of a HCCA225 Digital Reference (same board).
The BD1501 has proven time and again that it is a fine amplfier capable of some serious abuse. The new T-Series amps are a whole new monster though and fantastic performers.

ok, that's kinda what I figured...
Have you tried those new rockford amps?? I've been looking at the T30001BD because I had 2 PG elite's, but I sold them. Now my eclipse 8053 stopped spinning discs, so i've got the old alpine cda9835... shitty SQ compared to the eclipse.
