Conclusion: I purchased this sub; to complete a high powered audio system up grade in a 36 ft. motorhome. Space was issue, for the sub was going to be installed under a couch. The Bazooka BTA8100 was a perfect fit, and with only a half volume setting, it provides room-filling bass (remember its a motorhome) !
Spend your money on something better. Not worth the effort.

Summary: Meh. I expected better sound in this price range. The lack of any way to adjust the frequency response totally sucks. The separate remote adjustment for the bass level doesn't work like it should either (design flaw). After taking my car apart and spending a few hours installing this thing, I just said "to hell with it" and decided to keep it even though I am mostly dissatisfied.
Summary: It just isn't a stereo without a good balanced sub-woofer. I added this to my 2010 Ford Fusion SE factory stereo with Ford Sync. I also added wired remote volume control. It works seamlessly. Read the directions and you're good.
