Adding Amp to GS20

[wmccomis]

I added two more 7.7 tower speakers to my GS20, but it is clear the existing 4 channel amp is not providing enough power. What amp should I get to add to it and how is that installation process?

Id replace the existing 4 chnl with a 2 chnl, as they are perfect for the task of driving 4 speakers. My choice would be the Wet Sounds Syn-DX2. Out of the JL lineup, it would be the MVi600/2.
