I have a 2010 forte EX sedan and I want to install my JVC 70 watt amp and 2 x 10" subwoofer speaker box to my stock radio but I'm not too sure as to what I need. I read on some sites that I need and output converter and I found one at walmart that can hold up to 80 watts. Is there anything else I need and does anybody have a how to video? how exactly do I hook up the wires to my stock radio? Where do I hook up the remote wire? If anybody can help me out I'd greatly appreciate it.
