I went with the same blaupunkt speaker as Vikki in the rear of my 69 vert and one in each kickpanel up front with the stock speaker grills. I also tried one of the dual cone speakers in the dash but it sounded like crap so I disconnected it. I thought about doing a powered subwoofer under the rear seat, but it wouldn't fit so I located it in the trunk behind the rear seat. I also have the custom sounds secret audio under the driver seat with the controller and ipod attachment in the console.
