The Alpine PDR-F50 and the JL XD400/4 are both great amps if you plan to mount in the stock amp location. I have both and both are great very clean with great clarity and stereo separation, the Alpine does have much tighter bass due to a greater damping factor of >500 vs >150 on the JL. I do not think you will be disappointed with either. If I was mounting in a different location other than the stock location, I would go with the JL HD600/4 or the Alpine PDX-F6. I actually purchased both amps (Alpine PDR-F50 and the JL XD400/4) from Crutchfield.
