In the car:

McIntosh MC440 amp driving JL Audio XR400-CX coaxial speakers in-dash, run on a three-way crossover using a Canton Pullman 6" mid-base in each door, JL Audio 3" coaxials in a custom fiberglass enclosure for rear fill, and twin 8" Canton pullman base drivers (in the same enclosure) for bass.

All required equipment due to the convertable nature of the application, I'm afraid.

When it's not in the car, the Empeg is attached to one of these:

Office: Creek 5250 integrated amp with Vienna Acoustics Haydn bookshelf speakers

Home: B&K AVR202 with Martin-Logan SL3 electrostatic speakers
