Well I have 2 Audiobahn Awc12t 500 watt rms subs in a deep box I payed $130.00 for the subs shipped to my door well my friend Daniel bought a Alpine 15 type r 750 watts rms sub in a single deep box for $200.00 and a Lanzar vibe 1000 watt 4 Channel amp for $150.00 well he wanted to see what was louder a Audiobahn 12" sub running a the rms or a Alpine 15 type r running at rms well to my amazement the Audiobahn was louder why do you think it was???
My Guess: That Amp power is ovverrated by ALOT. And I think that audiobahns can use little power really well. The same way my friends Alpine MRD350 powers his extremely well.
