i think for a budget system you cant go wrong with JBL. We've all gotta start somewhere. i started with a 150 watt pioneer sub and some 5" 35watt kenwood coax. that was baaad.
there are 2 things you need to know about subs and amps. if an amp is struggling to drive a sub ie. the amp is flat out then it will send whats known as a clipped signal to the sub which will burn your voice coil/coils pretty quickly. and anything after about 85% of an amps gain "generally" is goin to be clipped.
however, if you keep this in mind and set the gains on the amp not too high you should get away with it. in an ideal world you would have somewhere in the reigon of 350 to 400wats RMS to power that sub efficiently.
When setting your gains, if you dont have a scope, set you head unit volume to about 85%, slowly turn your gains up untill the speaker goes distort (rememer turn it up very slowly). as soon as you hear this distortion back it off again untill its crisp clear. always start at minimum gain and build up from there.
hope all of that makes sense.
