Obviously you are going to use the Front pre-out's on the Sony to drive the Adcoms. its pretty straightforward, just do not use a speaker that is less than 8 ohms. and make sure that you always have the power switch off on the adcoms, let them sit off for 5 minutes, THEN hit the bridge switch on the back of the adcom's and follow their instructions for bridging. it's pretty easy and tough to go wrong. Good luck...Rob
SOURCE: how to bridge GPA 555 adcom amp from 8 om to 4 om
First of all, when bridging an anp, the impenence that it can handle usually goes UP not down. I don't believe that the GPA555 can be bridged without circuit modification.

SOURCE: can you bridge an adcom GFA-5802 power amp?
Running an amp in bridge mode requires a specific circuit design. It is not possible to combine 2 amps in this fashion.

This amp is not designed to be bridged and can not be used in the mode you wish. Sorry, but internal circuit changes would be necesary for the amp to work as a single channel.

SOURCE: adcom gfa 555 blows the 10 amp fuse and the 6 amp
Any fuse blowing is caused by a shorted component in either the power supply section or main audio amp part. Follow the fuse circuit and see where it leads you. Look around for burnt of damaged parts. Suspect anything sitting on a heat sink. The most common culprit is the audio amp main transistors, especially if someone shorted the speaker leads together. In the power part it could be the transformer, the large Electrolytic capacitors, rectifier, or voltage regulator. Some amps use an IC for amplification and this can blow the fuse.
