Won't require RCA's. I agree new head unit would be best but I really don't want to losse 6 disc changer. I thought initialy the stock system was decent but unable to handle any base and blew my cardboard speakers from Isuzu. I hope componets will tqaek care of mids and highs and basslink feed my lows. Any idea of other head units I would not have to loose 6 disc function wiht?
