Image Dynamics IDQ12D2 v.2 twelve inch sub in a ported enclosure. Enclosure was custom built to fit in the trunk of my 97 Cabrio (RIP). Sub originally cost $250; custom enclosure was $140. Perfect condition, sounds great. I'm asking $150 but am open to all offers. Pick-up only. LA/OC/Ventura. Will be listing amp separately would would consider a discount if you want both!
