I like these subs you don't need a huge amp to get deep and heavy bass out of them. I have them in a ported box with a Sony classD amp at 500w RMS at 1/2 gain to break them in and they slam. I like the look of these subs no chessy plastic or rubber on the magnets and cone. They have a big JBL 1000watt on them to let you know they mean business and let me tell you they do. I would recommend these for anyone.
