Looking forward in replacing my fact radio got from walmart a 200 watt Duel radio with the bell&wistle feature the problem I having is I don't want to loose anti-thift, willing to sacrifice? I bought a harness conection so that I don't cut fact conection harness, another connection among the same fact haness will not be used. What exactly is that conection; not mention in the picture found with in clubcivic forume on istalling 08 radio &indash kit, help is need? Also I was told I can use fact radio sound good but how do I use a amp with it theirs no RCA plugablity to the fact radio?
