Bridging two Orion 1200D's for 1ohm Load.

[Excalibur0428 10+ year member]

Im running 2 4-ohm Type-R's w/ an Orion 1200D at 1-ohm. I was wondering since the Orion 1200D's are bridgable w/ another amp (correct me if im wrong), If id be able to run two Orion 1200D's at 1-ohm with two 4-ohm subs.

I have never heard of Orion's being strappable

600D and 1200D are. Some say the 2500Ds are too...

The Orion.com specs claim that 2500d's arent strappable. But they might actually be if you know what you're doing.

the older versions are I forgot how but the ne versions def. are also the 1200D is for sure strappable.

Well, they are def. strappable cause it says it in the manuel.

supposed to be strappable at 2ohms stable. that the way i have mine

Does that mean that your two Orion's are only pushing 1600watts to your sub since the 1200D is 800 @ 2-ohm? Or will the two amps together push more wattage at 2-ohms since they're strapped? The Orion manuel doesn't explain the wattage for the amps if they're strapped, just how to strap them.

Here's the deal.

When you strap an amplifier, each amplifier will "see" half the load (just the same as when you bridge a 2-channel amplifier, each channel will "see" half the load). Due to this, the minimum impedance you could strap a pair of 1ohm stable amplifiers to (in this case, the Orions) is 2ohms since each amplifier would effectively "see" a 1ohm load and output their 1ohm rated power. So, a strapped pair of Orion 1200D's would output a total of 2400w RMS, since each amplifier would effectively "see" a 1ohm load and both would output their 1ohm rated power. And strapping them to a load lower than 2ohms would cause each amplifier to "see" a load that's lower than their rated stability.

So when you strap amplifiers, the lowest impedance you can strap them into is an impedance that is double what each amplifier is stable to on their own. For two 1ohm stable amplifiers, the minimum impedance when strapped is 2ohms. For two 2ohms stable amplifiers, the minimum impedance when strapped is 4ohms. Just the same as a 2-channel amplifier that is only stable down to 2ohms per channel cannot be bridged into a load lower than 4ohms, since each channel will "see" half the load (i.e. 2ohms)

Clear as mud ??

^ There ya have it. Either need dual 2's or a 2500d basically.
