For the cheaper sub they make you can't go wrong. These little things pound. Have 4 in my truck in a ported box and they definitely do their job. Dont mind the dirty truck in the video 😂
These subs are sweet have them in a boxed tuned to 32hz and just 2 8s on 1000w amp move quite a bit of air and hit the lows 10x better than expected
