Review on MB Quart Reference Under Seat Subwoofer by Beth Wilson

I installed a 10 inch subwoofer yesterday and so far it's just what I need in my 20's Silverado. Gives you some low frequencies that OEM radios can't. I won't knock on the windows, but it's good. The sound is very similar to when the car has a regular subwoofer. I still have to tweak that a bit. I will update my review in the long term. However definitely worth the money. After a few days of use, the subwoofer has a very harsh surround sound and needs some rest. Underneath I installed foam to reduce vibrations to a minimum. Gives a really good subwoofer sound. If you want more low end this does a great job on the low end but the mid bass sound is a bit distorted but I attribute that to more pause as the sound gets better the more I play. Now I adjusted the settings and it cracks, the sound is great. Might top it. I guess I have to buy another one for my Jeep.
