Ok so, trying to do this amp hookup. I kind of found a positive/neg connetion wire under the front driver seat of 1996 eclipse gs. I see this in my 1995 2g GS Eclipse as well.. Can I just hook my amp up threw the seat outlet or should I go threw the firewall? Seems like the person before me on the 1996 used it for that reason.. Found some RCA cables under my seat, thought that was why. Thanks!
