Not this week, but installed the Kicker subwoofer (with bass gain knob) about a month back. Took a week or two to get all the settings where I am happy. Initially I wasn’t sure I was gonna be happy with this purchase, but after getting everything tweaked, I am VERY happy with the difference it made! My buddy who owns a F150 King Ranch with the 87

speaker B&O system said it sounded really good to him (he’s a die hard Ford guy and we give each other crap all the time, so that was a big compliment). My wife’s Explorer ST has the B&O system with like 15 speakers, and it sounds really good. I am no longer jealous after this install!
Once I got all the truck and sub settings tuned (to my ears), I don’t have to touch the knob as much as I thought I would. But for <$50 I would definitely go with the knob every time!
