These subs are not what you really expect! They look good and make a joyful noise when hooked up but, put some real power to them and you will be back on Amazon buying more because you would have blowed them to HELL! They can’t handle serious power…at all!!!! I hooked them to a amp that puts out 500W RMS and that was the last time I played them now I have to buy more DAMN!!!!!!! If you simply just wanna nice bump while you rolling..KOOL..they can do that but, if you wanna compete….buy something else!!!!!!????!!!!????
