Classic looking sound for the Squarback

RetroSound in the states makes nice car stereo's and speakers. They look pretty classic, but are in fact fm/am radios and mp3 players. The speakers have 2 connections, one for left side and one for the right side... "stereo" with just one speaker. The speaker should be able to fit in the original mounting point on the dashboard, and the car stereo should fit nicely below. I have some more work to do on the car before I should wory about the sound system... but hey... a man can dream right!?
