    • Big Sound Little Package
Color: Single Subwoofer
Review Image by Stephanie Thomas Stephanie Thomas
I brought this powered subwoofer as a way to balance the overall midrange sound of my pickup truck. I was a little skeptical because I didn't know anything about the brand. The tiny sub did great ! It fit behind the seat with room to spare. It's not going to blow your windows of or shake your soul from your body but I will add a good amount of bass to your sound. ... show more

    • Great Sound!! Installed in a JEEP JKU
Color: Single Subwoofer
I got the kit with no wires or anything just the Sub and the Velcro/Attached Dial Bass controller. For all the naysayers you must be deaf this thing sounds it OUT. Easy hookup but previous owner already ran the RCA & Pwer/grd so just a plug and play in my KENWOOD touch screen.

    • Install kit was not included
Color: Single Subwoofer
Only giving 3 stars because we were shorted the install kit that was supposed to be included. So we had to spend another $20 for another install kit. Otherwise everything is great.

    • Stopped receiving sound after a month
Color: Single Subwoofer
At first I liked it it had some good hit for you know an all-in-one sub. Then literally while I'm driving to work one day sitting actually at a red light it cuts out I figure maybe it's a wire shortage something. Tested it to see if it was blown nope check the settings check the game all fine nothing was changed went back to a different amp and speaker those work just fine. This thing must have literally come loose or fell apart internally after a month. I would not recommend this thing it won't last long ... show more
