This is a Mercedes ML320 that we built a sub box into the rear passenger wall to keep with the factory look.
When we were done with this one it had phenominal SQ with all Image Dynamics Speakers Components in the front doors into the factory local, 6.5" Coaxial into the re4ar door factory local and a 8" Sub built into the rear passenger wall and a 5 channel Soundstream Amp under the rear seat.
He also opted up for the Pioneer AVIC F90BT Indash 2DIN
The SQ turned out extremly nice and it also gets nice and loud withthe 70 RMS to each door and 200 RMS to the Sub
