Adcom GFA5500 2ohm stable? & house wirinig

I am redoing my stereo & I plan to use my Adcom GFA-5500's to power subs & use my girlfriends parasound amps to power my speakers. Is it OK to run my GFA5500 in a 4ohm mono load or is that a bad idea? Looking at Adcoms site I beleive it states 2ohms is OK but I am not 100% sure that is the case .... just wanting to be sure.

Is it a good idea to run dedicated power directly from the fusepanel to the theatre area? We are redoing my house & I am thinking it would be good to run power from the fuse panel directly to where the thearte stuff is. At this time there will be 6 two channel amps all of which develop 200-300w at 8ohms. I figured with the current they can draw a dedicated powerline should be done
?. Is that a good idea or overkill? Next to the stereo stuff in a adjacent room (no wall seperating the 2) I plan on running a dedicated power line to my fishtank, about 500 gallons of saltwater.

thanks for any help/info!!

I've never been a Carver/Sunfire fan at all, but that's just my opinion. Please give us room size and all associated equipment and speakers, and then you'll get recommendations.

Generally speaking, I would not recommend Adcoms for a sub. You can do much better for under a grand (used).

So whatcha got?

Well, it really depends on what subs you're getting. You could consider powered subs, which would be better than subs and the Adcom.

There was a posting here a while back by a woman who bought B&W 801s and was disappointed with the bass. She was running them off an Adcom 200 wpc. Everyone suggested getting a "better" high- current amp. She did, and it changed everything.

It's not all about wattage when it comes to amps. There is a difference.

Yes, I do prefer Parasound to Adcom. I'd stay with what you have for the mains and surrounds.

I also would not rush into a sub until you're sure what you want. A homebuilt is a great idea if you're hand - there are plenty of designs out there. Another option is to use the Adcom on the surrounds and use the Parasound on the subs.
