The Adcom GFA-545 can't be bridged internally, it's not setup for mono operation. There used to be, many years ago, some type of device box that would bridge a stereo amp, but I haven't seen one for quite awhile. Not sure how well it worked...
bridging a Adcom GFA 545
Hi everyone. I'm new to this forum and a little green to home audio. Any help would be appreciated. I just bought a GFA 545 to power my sub and thought I could bridge it to get 400 watts. 200 @ 8 so at 4 ohms it should double, give or take. I'm a bit puzzled as the are no bridging lines going from the L to the R speaker outputs. Can this amp be bridged and if not can I do something to make it bridgable. Thanks again.
