Are they NEW or used at $90?? I could hardly find a buyer for mine when I tried to sell them. I ended up taking $120 in Best Buy gift cards in trade, but I would have rather taken less cash. If you already have MB Quart, why not go with the DTC series 6x9's. I see those on ebay for around $100.
Otherwise, the 4" MB Quart components I have forsale are already mounted on 6x9 cutouts....:naughty:
