I got a Pioneer Avh-3200DVD and want to install it into my Camry. What do I need to buy? or Can I just hook it up? I think my camry has a built in mini amp and comes with 6 speakers stock. 2 in back, 2 in front doors, and 2 tweeters. I got my paneling off already. Any information would be useful. 5 stars to the most helpful or that can lead me to the most helpful place.
