Big savings on car audio at PacificStereo.com, an authorized retailer for Kenwood, Alpine, JL, Pioneer, etc. I purchased a JL Audio TW3 sub from them a few years ago under a similar deal.
Coupon codes are in the 3rd attached pic. Up to 30% off. :
I grabbed the Kenwood DDX9905S (retail is $900) for 675 shipped. Arrives tomorrow
