The goal of the channel is to test all different brands and size subwoofers to give you real world and scientific data so that you can pick the best subs for your own car. We will unbox the subs, comment on build quality, test thiele small parameters, build boxes and test SPL on the Term Lab. The choice of subwoofers is driven by users! Leave a comment about what subs you want tested. Whichever comment gets the most likes chooses the next test. If the subs preform worse that the last video we will sell them on ebay! If the new subs perform better, the previous set goes on ebay!
