Hi
Please can someone tell me if my assumption is correct, I have a 4channel amp that i know is bridgeable to 2 channels. I have no instructions or online manual as its about 10 years old. If the amp is bridgeable does this also mean that the amp will be 2 ohm stable in stereo mode?
Just curious because Ive been told that a bridged amp sees a sub as a lower load eg, a 4 ohm sub is seen as 2 ohms and if this is true is it wrong to assume the amp will be 2 ohm stable?
Any help appreciated. Thanks
Ok, after reading some more I found out that the amp does not see a lower load, it sees the load placed on it, can I still assume the 2 ohm stable though?
In my experience no they are not 2 ohm stereo stable. generally if a 4 channel amp is bridgeable you can either run 4 4ohm loads, 2 4ohm loads (bridged) or 2 2ohm loads (bridged) now this is not true on all amps so the make and model might be helpful also as someoner here may know about your amp specifically.

It not a well known brand, its a starsound ssa 6040, about 10 years old, think it was called "The purple series" ON this amp I wouldn't have thought I could run 2 ohm loads when bridged and if I could run it bridged then why not stereo ( all 4 channels 2 ohm). I guess maybe there is no definite rule and its best to look in the manual but when the amp is this old and a "no name" brand its tricky to find out this info.
Most amps are 2 ohm stable in stereo but not mono. That means that you cannot bridge channels a-b to 2 ohms. You can run channel "a" to 2 ohms and channel "b" to 2 ohms. Same with channels "c" and "d".
