Replacing head unit in 04 Xterra

Beware when replacing just the radio in the 04 Xterra with A-pillar tweeters. The factory front and rear speakers are 2 ohms. You will blow your aftermarket deck. Almost all aftermarket cd players, tape players…are made to run with 4 ohm speakers. 2 ohm speakers will try and draw approximately twice the amount of power from your deck causing an overload.
