I gather the Thunderbird uses 5x7/6x8 speakers. I'd like to move to something larger (and also a size with a greater range of support), and so I was wondering, for those of you who've mucked around with this, what's the largest size of speaker you can actually fit into the stock mounts (both front or rear) while still keeping the original speaker grills. I want to preserve the original look.
