I just completed the subbox that has the same slope as the seatback so that it fits right up against the back seat. I will be wiring the power, speaker and signal cables soon. Lastly, the front speakers will go in. I am keeping the rear speakers stock with stock amplification. I cannot wait until I get this all in, but I have to go on vacation to Europe ;-).
I'll yake pics to show progress and the final install. I made the subbox with plexiglas on the back so that the back of the sub can be seen - its great.
