My headunit is a JVC KDG821
Front splits Kenwood KFC-P707
In the rear fill I have infinity ref6012i coax running of my HU.
In the trunk the is a Infinity ref1250w sub firing through the armrest. A Infinity ref7541a amp powers the front split and 2 channels brdiged to the sub.
Because my max dont have all the features the relay box in front of the battery is not that full. So I shifted all the relay's to the same row and place the fuse holder of my amp in the second row. Close but nice fit.
So my audio in boxes look like this
