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!!

Are parasound amps any good? I thought those amps are better then my adcom so I was planning on using those to power my speakers. Would I be better off to purchase a new/used amp to run my kappa 8.1 main speakers.... & then do a sub at a later date? Or use the parasound amps for the subs & all surround speakers & buy something better for the mains..... ??

I was planning on trying a pair of Image Dynamics IDQ drivers however a few people have steered me to 15" Tempest-X or th 12 in Shiva-X which they claim will perform better & cost me less. I am not sold on buying a prebuilt sub enclosure/amp due to how small the enclosures are & also being stuck to whatever amp is provided. I am trying to determine how much room I have to build a box & also waiting on the new specs for the tempest-x that is suppose to be released in a few weeks.

I also thought I could always try my Adcom & when I can afford to get something better for the subs I could upgrade at a later date? I thought giving my main speakers the best amp is my best bet....

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.

Yea, I am definantly not rushing into it. I have a friend who is going to make the enclosure for me (he's doing the entire entertainment cntr) & when I know how much room I have to play with I will then decide on which sub.

I guess I will have a better idea when the amps are hooked up what I should do. I have also heard great things about bryston amps & finding one of their amps used might be a option but due to their cost that will be a while.

That is a good idea though, using my adcom for something else..... like if I do end up with 7.1 they could be used on the kappa video's.
