My friend just got two Alpine Type R 12's run by an Alpine MRD-M1000 1800 Watt max amp, and they pump pretty hard, and do sound really nice.rwsupra.com said:I've currently got Kappa Perfect's all the way around. Bass wise, I'm looking for something with good bass that can hit hard when need be. I went to a car audio store today and listened to the Perfects and they just didn't seem to hit that hard at all even with 50 Cent in it. I did listen to some Alpine Type R 12's and they sounded pretty damn nice. I do like the Kappa Perfect 6.1's over the Alpine Type R components.
