Im an old schooler audio hobbiest. Building a system for a used daily driver its 97 escort 4 door, Im planning on running a JL 12w3 I got free, due to foam rot, which is only $25 to repair, along with the 12w3 some alpine POS amp came with it supposedly 200watt, I thinking about running half of one of my old school Power 650's on the 12w3, adn the rest on the high end. I got a box built and its roughly 5.25 cuft ported and tuned to 27hz. Im running an old sony head unit, it does have XM though.
