To Bridge Or Not To Bridge

Howdy. I have a Krell KAV-500 with five channels running only three Thiel SCS4 speakers. I don't have any need of the other two channels for the foreseeable future.

Anyone see why I shouldn't bridge two of the channels to give the center more power?

It sounds fine now but more power never seems to hurt with Thiels. The only reason I ask is that I don't want to undo all those screws if there is a reason not to do it in the first place. Thanks!

Schipo -- ROTFLOL!!!

Leo -- Bob R. makes an excellent point. In bridged mode an amp will see the speaker impedance x 0.5. The Thiel is rated as 4 ohm nominal, 3 ohms minimum. Therefore in bridged mode the amp will see 2 ohms nominal, 1.5 ohms min. I looked at the amp manual, http://www.krellonline.com/archive_pdfs/KAV500/KAV500_V990_MAN.pdf, and I see nothing that provides confidence that the amp will be able to handle that acceptably.
