Stop in for a cup of coffee
That's what I used on my Barracuda convert. Used a pair of 4 inch round speakers in the front and a pair of 6x9s in box's on the floor in the back. Rears have a quick disconnect in the wires so I can pull them out for shows, or if someone is riding back there. Reason for the 4inch in the front is I also added interior lights there.
