Finally a nice solution for fastback sound! 400 OBO
Custom box built for 65-66 fastbacks. The box fits perfectly in the trapdoor location. The box was professionally built in California. The box includes 2 Infinity Kappa 693.9i - Car speaker - 110 Watt - 3-way - 6" x 9" and Kenwood Kac-8405 720-Watt 4/3/2-Channel Amplifier with Variable LPF/HPF Amp. The truck gets sealed off very nicely and everything is hidden. The speakers are barely visible from inside the car - the camera flash makes them look visible.
