kind of sub and what do people think about audiobahn? are they any good?? im looking for something what will hit hard but clean. im going to run it with my stock bose?? let me know

thanks

 

i have two aluminum 10 inch audiobahn subs in my car and they hit harder than the 2 12 inch infinity perfects in my audi powered by the same 1200 watt audiobahn amp i have in both cars. in fact i am thinking about buying 2 more infinity perfect 12s to put in my a4 so that it will hit harder.
