i have searched alot of amp placement threads and it looks like under the seat is the most popular place.but my amp is too big to fit there so i had to figure something else out.
i decided to put it above jack compartment.
first i took some romex wire to get the contour of the panel and traced it on two 2x4's
a little test fit
painted them black really quick(wont be able to see em anyway)
cut hole in panel/ran the wires
then i took some decking i had layin around and traced the foot print of the amp,cut it out and painted it,mounted it on the "feet"
and the finished project..looks clean enuff.hope this help anyone lookin for a place for there amp.
