Just 2 amps? You should be able to run the remote to one, then put another wire in the remote terminal and run that to the other amp... unless your H/U is a POS that will work..
While you COULD run those off of a 4 guage main... I woulds suggest you go ahead and get some 1/0 for your main electrical runs, you can get it really cheap from http://www.weldingsupply.com, the just get a 1/0 to 4g fused distro and a 1/0 to 4g unfused distro, and a 1/0 inline fuse with a 200 amp fuse. That should pretty much have you sitting pretty, might wanna go ahead and get some extra 1/0 and some ring terminals and go ahead and do the big 3. If you don't have battery terminals that will fit 1/0 just let me know and I'll find you some that will work cheap.
No problem man, like I said, just let me know if you have anyother questions. (to a reasonable extent... [thanks to one person I have to say that now //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif ])
