Hello, I am an installer and technician in Philadelphia for over 20 years, ran a store (Boulevard Car Stereo) for about the same, so you can imagine all the crap I have lying around. Store closed over 5 years ago so not currently real active in the trade, but I have stuff I want to sell and would be happy to give free advice. I also collect vintage home equipment and play 2 100 watt Marshall half stacks. Greetings fello dizzeed loudness freaks and thanks to all who take interest.
