Review: Good compact powered subwoofer. - The subwoofer is compact but for my purposes has surprisingly good bass. I keep it powered to a middle setting and it is loud enough for me. The unit was small enough to fit under the driver’s seat of my car and the supplied cables were able to reach the head unit. Installing the powered subwoofer was easy but required me to remove the seat and cut two small holes in the carpet to mount the mounting bracket with the threaded posts to hold the subwoofer down. The main power wire is thin but I believe adequate for the power needs of the amp without issues. There is no hum or ground loop that I can hear. Also I do not hear any rattling of the subwoofer due to the way it was mounted. I would imagine a 10” subwoofer would be far louder but that was not what I was looking for. I am pleased with this purchase and I have had zero issues with it since it was installed several months ago.
Review: Super quality - Excellent sound quality at a great price. Fixed it in my Land cruiser, under the driver's seat. Wow! Super experience.
