I was just given a jvc single din radio with dvd navi ect but im told it some times freeses up of the face plate wont swing down or it does else something stupid. I have the factory infinity amp under the back seat and was wondering if i should just hook it to the speaker outputs on the head uint or make some adapters for the line level outs and wire them into the amp? I dont want to spend a lot time bypassing the factory amp it this thing is going to crap out on me in a week.
