hiendmmoeBe aware with bridging, yes you gain watts if you need to go louder, but you loose too.
Less damping factor (the ability to control the bass driver)
Less current drive into low impedance’s.
Higher distortion.
So unless you need more watts just so you can play louder, your better off not bridging.
If you want you could go bi-amping with a second aw250r if your speakers have separate terminals, this will be way better than bridging.
