I bought my truck about 2.5 months ago and finally ditched the subwoofer. I'm not a huge fan of heavy bass and it takes up too much room in the cab. This weekend I installed a 2008 back panel in my 2009 access cab - removing the subwoofer in the process. Removing it this time was more difficult and I ended up with a small scratch on the upper drivers side of the subwoofer enclosure.
Anyway, if any of you want it, I'm selling it for $200 plus shipping. I've seen it retail for $415. I'll include the lower mounting bracket and all bolts. I will not cover any customs duties that might be incurred.
Please verify whether your truck will accomodate this subwoofer. Tomorrow, I plan to post for sale my 2009 back panel which has the cut outs to accomodate the subwoofer.
