Anyone got a 5.1 setup in their car?

[helotaxi 46]

I'm thinking about going with a 5.1 setup in the truck. The front channels will be 3-way active and I'm thinking Legatia 4s for the surround channels and the center channel. Amps for the surround would be OLD US amps USA-100 and a USA-25 bridged on the center channel. There's a nice pocket in the top center of the dash for the center channel and the rears will be in pods up near the ceiling. The HU I just ordered is 5.1 equipped (Kenwood Excelon DNX-8120) and the sourround will only be used on multichannel source material with just the fronts and subs on music.

Thoughts?
