Oh I know what they ran and no way in hell it would make 1600 watts. It just didn't. Deny it all you want. Dream whatever you like. It wouldn't do it.

The only amp that had that kind of jam back in the day was the Colossus. Everything else hit the wall in the 1000-1200 watt range back then.

My SQ car is purposely all Class A/B. The SPL car is a little different but then it's an SPL car, might as well save the current on the sub amps.

And I never said A/B could not make power - just that a 275HCCA will not make 1600watts. :ohwell:

must be the cheese:)

yeah, i don't run comps at all anymore. I've got an alternator with current to spare, might as well just go all out - I'm a dedicated a/b kinda person. If I'd run an SPL car i'd definitely go with class D, honestly there is nothing better for SPL, just the thought of going from .005%THD to 1%+ in my personal car doesn't appeal to me:dunno:

^ You can't hear 1% eh. Yeah it looks bad from a technical standpoint but it's inaudible.

Audible Threshold of Class A/B Distortion
 

^^ Now that you mention that one tidbit, what is the threshold of where distortion becomes audible with A/B power? Wasn't it like 3 or 4 %?

BTW I run 1970 Watts Class A/B in my daily driver :) Lovin' it...

Guys I know the db sounds outrageous but case and point. I mimiked the enclosure of a Paradigm PS 1000 Home theater enclosure x2. Each PS 1000 will shake your neghbours house... don't believe me goto any quality home audio theater dealer and crank one... no.... two.. all the way up and tell me that isn't crazy db's in your HOUSE let alone a car.

Not only that but they were rated to 100 watts 1% THD and are 10" subs. NOW I'm throwing in 900watts and to dual enclosures.

As for the amps being sold I think it's all demographics... I mean you goto comps and you see people running db drags not SQ. Companies pump out high wattage 10% class D amps cheap because kids buy them. Lets face it, few people, if any, care about SQ in their cars. They goto "westcoast customs" and they throw in thier cr@p audiobahn stuff. Companies don't pump out class A (real audiophile stuff) or an expensive A/B amplifier because db people want db's not SQ and few people are running or care about real SQ anymore.

Also 1% THD on an oscilliscop is very obvious. The clipping effect is what damages speakers. Class D's do clip and same with AB during the cycle change. The only amp that ANY home audiophile user will take is a class A. AB running a close second.

You don't think 1% is a big deal... get into SQ home audio and tell them they have to run 1% THD. They would take your head off.

EDIT: Found this on www.hometheaterforum.com real quick
" ..look for the lowest THD ratings and true wattage at 8 ohms.You want THD at .08 or less...
As a side note. Also remember the watt rating on an amp isn't always an accurate one. Things to watch for are amps that give their rating at 1khz instead of from 20hz-20khz. Amps that give THD numbers higher than 0.1 in their power rating. Amps that don't specifiy all channels were being driven when this power output rating was obtained. Amps that rate into 6ohms but say not to drive 6ohm speakers. So as an example take these two specs:

1) 110W at 1khz, with 0.7%THD into 6ohms (on the front of the box they also claim 110Wx5 and in the manual say not to drive 6ohm speaker with it)
2) 70Wx5 (all channels driven) from 20hz-20khz, with 0.08THD into 8ohms (manual says you can drive 6ohm speakers)"

well, with 18000 watts, what do you use it for? By the way I'd love to see some photos of your set up and the electrical system that pushes the 3500 plus amps required to actually realize the output for any sq based length of time. That's one hell of a daily driver...and you're not deaf! I'm not doubting you have it, just that it's completely useless for an SQ(which you seem to be promoting via your amazing old school specs) set up. That sounds like an spl set up to me. The other problem i think most of you will find is that at the ultra low impedances that those amps produced their max output, they would have also produced significantly higher levels of noise, distortion, and would certainly not have the same damping factor. Anyway here's an example of a comparison from a manufacturer of their old school high power amp which by all accounts is very highly regarded, and thier new comparable model. Remember, according to you guys, it's manufacturer's word as to specs etc... and should be relied on. See link below:

18000 watts? wtf? Man, so if you guys can't win you lie? what's goin on?

and if you knew anything about Orion HCCA amps, you'd know that peak power output is achieved at 1ohm. Will it go to .25? Of course, that's what the old school had, but will never deliver more wattage, just lower damping and higher distortion.

OH ALSO - .005%THD isn't an SPL number. LOL! And maintaining 3kW isn't that hard to do if you've ever heard of something called a high output alternator.

Hey hey! Well your buddy dukk says it's all just corporate propoganda - and if you want me to believe you then i can't believe him? Damn, all your contradictions!
