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!!

Back again.Please use a Hospital grade outlet
by a good brand name like Hubbell. It will
give a better connection,resulting in less
noise,and cooler running connection.

awesome.... thanks for the input everyone!!!

My car audio adcom stuff is stable below .5 ohms but I didn't think their home amps were built like that. I guess I need to either get 2 subs that will allow the channels to run at 4ohms.... or fund a different amp to buy which is definantly a option. I only have 1 gfa-5500 now & maybe instead of buying a 2nd adcom I should look elsewhere

So 2 20amp lines is what I will do .... & thanks for the tip on the better grade outlets!!!!

The GFA 5500 I used to have back in 99 ran very very hot. They are decent amps for the money but you can get much better for not alot more. Just my opinion. Yes 2 subs will take a big load off the amp for sure. That might be the best route to take.

Any suggestions on what amps I should consider? I only paid $400 for my amp.... probably can't go much more then $1000 for whatever I would buy. I have had my eyes on sunfire stuff.... how are their amps? I saw they have a amp that's 600x2?

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?
