I have just installed 4 Momo120's in the back of my Hyundai Tiburon...Yes 4 in a small import. I am pushing them with 2 Kenwood 401m amps! A fellow poster on this board has had a hand in the install (kStrange65) This car has had many different subs: the db10, db12(kenwood), 6000's, 8000's(mtx) and finally the m120's by far the best. I just want to give props to Polk and say that if you want good clean sound consider the 401M for power.. Its awesome... I'm currently breakin the subs in but they still pound. 2 questions to Kim...Do you believe that I have enough power or should I consider something more??? When I took the subs out of the box I pushed them in as far as they would go and pulled them out in the same manner under recomedation of a professional installer at Circuit Cty...Do you suggest this??????and Why????
