look into alpine. look for some type r's or if your wanting something less ''beefy'' lol look into some of the lower models like type s or type e they all sound very good
the punch series can't handle a whole lot of power. I heard a few of them in person, and wasn't pleased with the performance at all. However, they are pretty cheap, but there is much better for the money.
I have 2 12' Punch p3's giving them 600rms a piece in a vented enclosure and they get very loud but their SQ isnt that good. they are well built subs and could handle high power. I just order 1 alpine Type R 12 I will let u know how they compare as soon as i get it.
