exactly as the title says, is it safe to run an stereo subwoofer amplfier at a higher than rated impedene? i know most people are doing the exact opposite and trying to run it at the lowest impedance but what im looking to do is this: run my hifonics colossus XI amp at 8 ohms stereo to power 2 JL audio 12" w6's rated @ 400W RMS
My amp puts out 600x2 @ 4 ohms RMS

So theoreticaly it would put out 300W X2 @ 8 ohms correct?

And another question is would i damage the speakers if i just ran them at the amps rated 600w RMS X 2 @4 ohms?

 

8 ohms word, its cool

 

sweet thanks

 

8ohm ftw

 

Impedence represents a load.

The higher the impedence the less of a load it is to the amplifier.

An amplifier will work harder to drive a low impedence load.

Your amp will run cooler when driving a higher impedence load.

 

damping factor will go up as the load is raised also.
As long as you dont have a JL amp this is not a bad idea.
