The system in my car is slowly becoming a homogenous Alpine setup, primarily by attrition. I started out with a mix of components from various manufacturers and now am down to three: Alpine (head and subs), MTX (amps) and Kicker (components). Lately I have been thinking about switching my Kicker components out for some of the Alpine Type-R full range (coaxial) or components but haven't really decided if that is the path I want to take. So... anyone here using Type-R stuff? If so, what are your thoughts? The ones I am looking at in particular are: SPR-174A 6.5" coaxial SPR-574A 5x7" coaxial SPR-176A 6.5" component Other suggestions are welcome. My emphasis is on sound quality, not SPL ... although the twin SWR-1021D subs do hammer nicely.
