I am slowly starting to warm up to the idea of modding my new-to-me SDA SRS's. I've had them for a month or 2 now, so I know the sound. I got the new tweeters, and am thinking about the Dynamat/ JB Weld mod to the mids/base drivers. There're sure are quite a few choices as far as size and amount for the Dynamat. Which is the best choice for what I'm about to do? Thanks in advance.
