2 8's AKA Jeepbeats

Hey, I know a guy that is selling an Orion 425HCCA 4 channel amp. They rated them as 25x4 rms, anyone know what they do, real world power-wise? What is a decent price to pay for one of these in good working shape? Stable down to low impedance? Thanks for any help given.....

If i remember right they would do 1 ohm mono @400 RMS and 200 RMS .5 ohm stereo./ch

Thanks, so if I am running some components off the front at 4 ohm stereo, and subs at 2 ohm mono off the back half, the fronts will not be running at the full capacity of this amp?

hey,
those hcca's are indeed rated at 25 wrms x 4 but will bench test at anywhere from 65 to 80 wrms per channel. the amplifier is not perfectly efficient to actually double power everytime you halve the impedence. further, they will actually put out over 500 wrms bridged at 1 ohm. they will also do .5 ohm bridged and put out over 600 wrms although not recommended.

you will find the fronts to be well served with this amp i'm sure. its a very clean sounding amplifier also... i love mine.
as for price, who knows...

Thanks for the help, Mr.Marco, looks like about $200.

Mr.Marco did you sell the Kicker 600.4 btw?

Thanks Paul, I found some manuals for the really old 425hcca's, looks like some of them needed a separate bridging module to bridge it, and they used crossover cards, also. Have to see if that applies to this one.

The first gen 425 needed a bridging module. It did not have crossovers.

The 425 was discontinued for second gen but reappeared for 3rd gen. It did not require a bridging module. It had quad module slots for cossovers.

Mr.Marco is correct as the amp will do considerably more than rated especially at higher impedences and will not quite double when impedence is halved. I found however that the amp would do closer to 600rms at 1ohm bridged.

$200 is an absolute steal. $450 would be an average price for the 3rd gen in good condition and $300 for the first gen (they got really hot at lower impedences also. Like turn pink hot).
