Summary: Well, this sub carries the name "Rockford fosgate" but I am very disappointed... I am on a low budget but I am in love with loud impressive bass. So, I went ahead and bought two of these and two of the punch 1000-1 bd amplifiers and well, the amplifiers are very impressive but these subs are not. They cannot handle power, I have my amps set to half power running at 4 ohms and I have to baby these subs because they overheat very easily..
Conclusion: I recently purchased this sub after selling my old 12" Pioneers and all I gotta say is wow! This sub is really loud no problems so far and im running it on a hifonics 1200 watt amp at 900 rms.
Summary: I basically wrote this review in response to the guy using two 1,400 watt amps to power two 600 watt subs. Man learn how to read you're way over double power per sub one punch 100.1 bd amp will power these subs. i have 2 of these subs on a prime 1200.1 amp birth sheet says 1398 rms now i am giving my 15s almost 700 watts a piece rms at 1ohm and they don't even get warm, nor does the amp. You probably don't even have them running in 4ohm either.
