This subwoofer is perfect for a stealth install, it sounds very tight and loud but no port noise like a ported enclosure can make when pushed hard. Got it when it was on sale for $212, normally these are $249. I have it under the cargo floor of my SUV so it doesn't take up any available cargo space, pushing it with a Rockville RXDT2 at 2 ohms bridged and it fills the cabin with smooth bass. For the price of a custom box alone, I put one of these in my vehicle and got bass without losing space. I thought I might need two, but one is plenty. Plays the lows and doesn't distort, plus doesn't tempt thieves due to the install. Love this sub!
