I was about to buy the 6 1/2" Sony Xplodes for the rear deck over the week-end since Brooks verified the exact speakers. They are the XS-V series. All of these should drop right in. I understand that the Infinity 6 1/2s need just a little cutting to make them work in the back. By the way, those Sonys are very ugly looking and I really would not want them showing on the back deck unless they had very superior sound. Anyway, my son went to Tweeters to listen to the Xplodes and he did not like the sound. The guys at Tweeters said that the Boston Accustics were better. Now my question is, will the BA 6 1/2s fit in the rear? And the other question my son has is: what is the cheapest way to add a sub-woofer to a 190E? Searching the posts here last night, there are a couple of ideas. I think I will wind up with a free-air 10" in the FirstAid kit area with an amp with enough power to drive just the sub. Head unit is a Bekker with 4 x 50 watts and that should be enought to drive the four small speakers (2 front, 2 rear deck).
