This is a great tube that SAS has put out. The lows that are produced from this tube is great and accurate. I listen to all types of music and it all sounds very good. you cannot find another sub for this price, quality, and enclosure. it is a great space saver too, and very easy to remove if you have to. i wish sas would include the upgraded mounting brackets along with the straps so the customer would have of choice of how to secure the tubes. the 5 way binding post are great and provides numerous ways to connect this sub in reference to ohm load. This tube sounds awesome in my Durango. This sub hits plenty hard enough and brought a big grin to my face. I like it so much that i might add a second tube just so i can start turning heads even sooner before i arrive at the scene. by the way, people could hear me coming from about two blocks away!
