    "What a Dynamo don't let your skeptic stereo installer tell you anything different I love the crisp balanced sound. I'm into my 2nd installation on this unit one 8"" and another 10"" on my G55 AMG w463 Slides under the seat plush. . The customer service department is sterling you can even get customer support on a Sunday. . . Superb quality and value. . . Kind regards Dr. G"

    Wasn’t expecting that!

    "I purchased this for my 96 Chevy truck, and Wow for as small and compact as this is it puts out very good bass once I got it tuned for my truck. For a 8” sub it fills the cab with plenty of low end to complement my stereo system perfectly. Way to go Rockville this is a perfect addition to any setup where space is limited."

    Went with 2 of these in 3500 crew cab

    "Well have to say VERY IMPRESSED!!! I bought one for a single cab truck and was impressed with it so decided to put a pair of these in my crew cab 3500 dually and WOW!!! did it come alive, ran a split signal to each amp at full low level voltage and she’s a banger can’t believe how much bass these little enclosures put out and clean bass too and without taking up useful space in my truck. I have both amp controllers mounted under dash so I can control the amps from the front seat which makes for the perfect setup and give me versatility to run one or both amps and have complete control over them depending on genre of music I am listening too. Will be installing one of the 10” my cars trunk as an experiment to see how it does. Will write a review after it is completed."

    Fantastic for the Price !

    "Had an old Rockford Fosgate powered 10"" die after about 5+ years and a friend of mine had one of these Rockville unites in his BMW M4, so I took a chance and it sounds great in my Audi A5 coupe (along with my stock sub) ! Doesn't take up any real space and the hookup and controls are easy to use/navigate. This is a great add on when space is limited."
