I have had an Alpine/Boston setup in my truck since 1998 Boston's are awesome sounding speakers. rx series 5x7 coaxials and a 10" competitor sub. Neither of these is Bostons top of the line. Not bragging but they sounded better than anybody elses. I don't have a huge mega amp (5 channel alpine) so I couldn't compete for loudness, but nobody has ever beaten that system for sound quality. Boston's are not cheap but you get what you pay for. When i bought this system i listened to pioneer, sony, rockford, Mtx, and alpine speakers back to back. nothing sounded anywhere near as good as the Bostons.
