Actually in a case like that, the amp would blow the subs, at the least distort them. Had a Memphis 600 watt amp pushing 2 Memphis Power Reference subs rated at 450 watts peak per sub... it actually blew them after a couple years and only once went into protection at a competition when it blew one of the 4 25 amp fuses on the amp... still have the amp to this day just need to more subs for my GTP....
i think Crunk is right with it being a lower class amp and he needs to up it on class... there are TONs of cheap efficient amps that you can get that will push good subs without this problem. Plus ive seen this same problem on a Jensen amp 2 times before my friend upgraded to a pioneer amp, that fixed the problem, kept same subs, wiring, just replace the amp and the problem went away.
