well you could have had your gains set messed up man. just b/c you blew your subs in a matter of mins doesn't really mean jack to be honest. anyway the 2001 RF punch amps versus power amps were about the same, hell i have a 120.2punch that is rated at 220 and a 200.4punch that is rated at 450watts, this years punch line sucks though i haven't seen an amp do over %65.
keep it thumpin,
