I kept my amp and replaced all of my speakers with Pioneer and then later replaced my HU with Pioneer. I am very happy with the results. Replacing the door speakers with 6.5" speakers definitely improved the bass response. I do get some mids and highs through the door speakers with the stock amp although they are not as clear as the dash and rear speakers.

Keeping your factory amp and just replacing your speakers make a difference in volume? I was more looking for volume so i can hear with the top down i am less concerned about loud bass. Although that would be nice
