Ahh... okay. I still have my stock setup and am just wanting to switch out the 6.5" for the 8". I assume there is some sort of connector plug going to the stock sub with + and - wires and I can just cut the connector off and attach the bare wires to the new sub.
I think it's going to be a bear getting the new sub in the stock enclosure though, but hopefully I will get some better sound out of it. The JBL system isn't all that bad for a stock system. I already replaced all the door speakers. However, that stock amp is a major POS. It is causing static in my right rear door speaker and distorts some of my CDs (even if I play them at low vol).
It will have to make due though until I can afford to dump a couple thou into replacing the entire system.
Thanks for your help Jason.
