I'm looking to replace the subwoofer on my '91 EB, and after reviewing various threads have found that the JL 6.5" unit will fit, but what I can't find a clear answer to is this: Do I order the 4 Ohm or 8 Ohm? :us:

Sorry I can't answer your question, but if you want more than the 6.5 you can get an 8" and modify the box. It took me less than 20 minutes with a dremel and is sealed just fine. It's just a generic sub and sounds better than the stock system.
