Hey everyone, I'm fairly solid on my knowledge of car audio...but i just bought a 2005 Honda Accord Coupe with the dual climate controls and am trying to figure out how to transfer my stereo from old car over....does anyone know any solutions that are actually worth the trouble they put me through...(would like to retain use of climate control) or any easy ways to add a 4/channel and/or amp and sub to the factory system so i can keep climate controls....

I've looked at line converters and 4channel with good speakers but don't know anyone that has done this setup so i would like to know how it sounds....and if there is a way to add a sub to it...else i have to find a new home for my 12' infinity sub..
