Wondering if anyone has had good experience with either of the sub mounting brackets I've been reading about on Mud--the 8" from Whole Hog or the 10" from (I forget). Which would you recommend? Are either plug & play, or is there a lot of futzing around, fabbing enclosures & all that? Having this done at Best Buy, so whichever yields acceptable results is the way I'm going. Don't want intrusions into cargo space and don't need to impress the car next to me with the depth of my boom. All advice very much appreciated.
