I'm looking into upgrading my head unit and I was wondering if anyone on the forums has the CDA-117.
It looks like the CDA-117 has replaced the CDA-9886/9887 because they have been discontinued.
The 117 does not have a built in three way crossover that the 9887 has. You have to buy the IMPRINT device in order to have the crossover feature. However, it does have Time Correction, MediaXpander, and the other features that the 9887 had.
