This "premium" coupe only came with one power seat, leaving a bit of room under the passenger seat for what appears to be a power module of some sort... a black box with cables. But it doesn't look like audio if you know what I mean. ) The cables appear to go into the seat, perhaps for the heater?)

There are 6x9 speakers (low impedance?) in the rear deck, but no sign of an amp... next stop is the dealership for some Q&A!

And thanks to all for the "acurate acura advice".
