BIGglaSS, I ended up using the L/R rear high inputs as you suggested. Not sure if my splitters were no good or what -- got nothing. I have adjustments made as you suggested. I did adjust the gain down on the 2 --- 5.25's ( about 1/3 on the Clarion) as those have some bass on them also - both under driver seat.

For cutting no holes or adding foot panel speakers, this setup sounds pretty good and I am very satisfied with my results. Bass addition from the 10" sub is nice. I pretty well did away with any stereo effect but not sure how much it is beneficial in a small truck cab.

A head unit with sub rca's out would have been a cleaner install - maybe next time.

I thank you for sticking your neck out to help someone clean up their mess as to a better solution.
