That amp will not blow those subs. You have pretty good subs, and a cheap amp, no offense. You should never cheap out on the amp, its the most important thing in the system, probably more important than the subs. You probably got it because you thought it pushed out a lot of power for the money, compared to other higher end brands, but what ppl dont know is...
These brands overrate their amps to sell more, and they will NOT push out as much power as they say they do. Heres a easy way to tell.. find the fuse size. Multiply it by 10. that is the rough estimate of how much power you are really getting. if there is 2 fuses on the amps, add them. This is your proof! So try to get a better amp, and pay a little more if you want it to sound a LOT better!
