I have a profile ca600m mono amp. The rms at 4ohms is 300 watts,600 peak . I need a sub. Im going for 1 12inch. Im thinking about getting either a Nakamichi 12" SQ Subwoofer, or infinity 12inch reference series. The infinity's rms is 300 and peaks at 1200. The nakamichi's rms is 200 and peaks at 400. Which sub would be better? I know that profile amps have a reputation of over heating ect..... Note that im a broke a*s student that just wants some clear bass. Helkp would be appreciated. Thanks
