Thanks for the ideas. I tossed the idea of the 21" sub by my boss and he shot it down. Lol. I think i need to look at just pushing the idea and like u said, just order them we get that basshead customer. Weve had a few people asking about 18s lately, even have a customer wanting us to build an enclosure for his BTL 18. Which im very excited about. So that being said,do u guys have any other ideas i can present to my boss to change things up and get people excited? We are pro Rockford Fosgate at this shop. We also carry Alpine and Kenwood just to give you an idea of what we already have going on.
