Is the only thing keeping a sub amp from being full-range the preamp section?

[size=10pt]Is that where the Xover is? I have a couple of sub amps with fried preamp sections and was wondering if it would be worth tinkering around with these as full-range amps.[/size]

The amp section shouldn't care what signal it sees. The crossovers are either done in the pre or on the input to the sub. Model number and brand would help.

[size=10pt]They're Proficient S66 subs. Originally they powered two 6" "subs" (I call them bass extenders) per sub in a sealed enclosure. Really nice, tight bass. The amps have some big ol toroidal transformers on them.[/size]
 
[size=10pt]I bought new amps for them and was just wondering if this would make a fun project or if it's a waste of time. [/size]
 
 
 
[size=10pt]BTW, Did I mention I have two of the amps?[/size]
