Question on AMP POWER

[Realbleach 10+ year member]

Hi

I had a question for experienced audiophiles....

I was always led to believe that if 2 subs were hooked up to an amp in MONO that each sub would see HALF the power watts..

Example

If i had 2 subs in parallel hooked up to a 1000 watt amp (in MONO) that EACH SUb would be getting 500 watts each....

BUT i see on the Orion website that this is not the case

If i am reading it correctly then the same scenario above according to Orion that EACH sub is getting 1000 watts !!

Which is true ?

both cases are true

ex:

a 2 ohm stable amp running a 4 ohm sub @ 1k watts will generally push 2k watts @ 2 ohms with another sub wired in parallel, so each sub would get 1k, but it would be rated higher than just a 1k watt amp

here is the Orion amp i am talking about

Model Number HCCA-D2400

Max Power 2400

4 Ohm Rating 425 x 1

2 Ohm Rating 800 x 1

1 Ohm Rating 1200 x 1

Notice it says MAX power 2400

YET at 1ohm it says 1200

If i am reading correctly then when 2 subs are hooked up (two 2 ohm subs in parallel) then each sub would get 1200 watts EACH this giving you a max power of 2400 ...

Is this correct... ?

I always thought if i hooked up two 2 ohm subs in parallel for the one ohm load that they would EACH be seeing 600 watts in the scenario above ..

Not only does orion display this some other amp companies as well

With that amp and running 2 subs wired to 1ohms each will receive 600w rms

The RMS power of that Orion amp is all you need to concern yourself with. The Orions don't defy physics. Just like every other brand that talks about 'max power' you should ignore that number entirely.

Umm...no, both cases are not true.

If you have an amp that outputs X number of watts @ whatever impedence then if you connect a single sub to that output then that single sub is going to receive all the wattage being output into it.

If you connect two subs to that output then each sub will receive X/2 wattage.

Three subs will result in each sub seeing X/3 wattage. (all of this is assuming that with your particular combination of drivers that you can achieve the necessary impedence to cause the amp to output X wattage.)

The RMS power of that Orion amp is all you need to concern yourself with. The Orions don't defy physics. Just like every other brand that talks about 'max power' you should ignore that number entirely.

"Max" or "Peak" wattage ratings are good for absolutely nothing more than marketing purposes. They can be completely dismissed and you'll never suffer for having done so ~ I promise. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

generally crappy companies put in max power ratings so hopefully orion is falling towards the pack
