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.

My woofer is a JL 10W7. Its a single coil @ 3* I am very upset that it cant be bridged. The speaker is rated at 750 watts. I am running the speaker on 1 of the 2 channels. It sounds OK and this little amp is not even breaking a sweat. I need more power!!! I have a THX Pioneer Elite and in the speaker setup menu I had to add 6 db to the sub. At 3* with only 1 channel driven, how many watts would you say I am getting to the speaker? And is it ok to just run 1 channel? Thanks
