I compared the stock sound system to the Alpine sound system yesterday. The stock system is definitely improved on the stock JK system. The only problem I can foresee is the loudness of the system. In my opinion, you might have trouble hearing it with the top and doors off. The Alpine system is of course louder and has more bass, but personally I think the sound quality isn't as dramatic as in the JK systems. I ordered the Alpine system because of the loudness, bass, and I wanted the larger screen.
