Thank you fellow Amazon members. I bought this subwoofer for my Jeep based on your recommendations. You were spot on. It’s a tank, built very well and delivers unbelievable bass even at 0 level. I can bump it up to +15 and rock the windows if I want – and I don’t.. It’s exactly what I was looking for and works great. The floor of my Jeep under my seat is very contoured so I couldn’t mount it there – I mounted it behind the rear passenger seat and it’s awesome.
