I have an 2003 IS 300 sports edition and want to add an amp and subwoofer to the existing Lexus stereo, is this possible? I was told that it can't be done without re-wiring the whole car and maybe even re-placing all the speakers and head unit. I want to upgrade, but I'm not jazzed about that proposition. Any thoughts or suggestions? Has anyone had a similar experience?
