2100 HCCA digital reference is stable only to 2 ohms mono whereas the 2100 HCCA competition amplifier is stable to 1 ohm mono. What makes the difference? Is the competition amplifier only stable at 1 ohm for short bursts? Are they essentially the same and the digital reference can be run at 1 ohm?

 

You wouldn't be able to operate an amp on short low-impedance bursts unless you were physically connecting and disconnecting speakers of a low impedance, really fast. And why would anyone do that?

Since one amp is called "digital reference" and the other "competition", I'm going assume that the first is more of an SQ amp, while the latter is a SPL amp.

I wouldn't try running the digital reference at 1 ohm if its not rated for it. Perhaps they have the same exterior shells, but the guts of the Competition are designed to operate on a lower load, and with more heat, to give you more power.

I don't have time to check their specs out right now. But I'm going to assume that the digital reference amp is less expensive, and you'd like to get the same output from that unit as the competition. Likely not.

Hook a 2 ohm sub to the digital and get whatever the amp'll give at 2 ohms.
Hook a 1 ohm sub to the competition and get whatever that amp'll give at 1 ohm.

 

do you know what hcca stands for?

 

High current competition amplifier.

Back in the day (20 years ago), the were considered "cheater" amps because they were about the only ones that would operate at lower impedances. The old SPL rules classified you at face value of your amps. You would be in the 0-200 watts class even though your amp made MUCH more power.

 

that amp will put out power at pretty much any impedance as long as you give it sufficent current. i have owned a couple of them and worked down with mark busier for a while at orion and that amp is the cats meow........ for the 80s and 90s.

 

I know what HCCA stands for but I also know that there was 2 versions of this amp (besides different generations) and that there was a difference in the ratings between digital reference and competition amplifier.

 

I forget what one it is but my cousin had an old red orion hcca amp that was about 2 ft long and it was retardedly loud...he was pushing 2 alpine type R subs bridged to 1 or 2 ohms...it was ALMOST stupid lol! Not in our case but apparently theyre prone to causing fires. Great amp if you can find one with the plugs still!

 

Finding plugs for old Orions/ADS/PPI/Audio Control/(and I needed the plug for an oldschool Phoenix Gold Bass Cube, not to mention the LP44 for the remote ****) was a pain in the *** until i found this site.

If you need parts for an old school amp or those hard to find cables (them damn dongles that you need for the A/D/S amps them check it out, there even cheap to boot.
