I just want to knwo some good subs that will hit pretty hard and arent that expensive and can take around 600rms from an alpine mrd-605. Also why dosent anybody comment that much in the amplifiers section?
if all ur going to be pushin is the 600rms, your not going to get any louder than the type r already is. a new sub wouldnt really help in your situation. but if i were you, i would get a new amp, and get 2 12s. another type r, and a 1000rms amp would work.
