Dynamo 500 plate amp swap???

I have 2 Dynamo 500's and they both have the same "popping" issue. The Dynamo 500's I also noticed when they are in fair working order are not "quick" enough to match my Theos towers which got me wondering if anyone has changed the factory amp to a faster and better quality servo plate amp? I have also scoured all my resources to the best of my knowledge and cannot find a single DIY fix for the popping issue (Im pretty sure its a capacitor issue in the plate amp from what i could actually find about the popping issue) any insight or suggestions would be greatly appreciated (cant afford a Depth i or Balanced Force at the moment so buying a new sub isnt happening anytime soon).
