Review: I have these Alpine speakers in the dash and soundbar in my 2003 Wrangler and they’re connected to an Alpine UTE-73BT multimedia head unit. The sound quality is excellent. There isn’t a ton of bass but I was expecting that. I always had trouble hearing the music with the windows rolled down while driving on the highway but now that’s not a problem at all, my music comes in very clearly. I think these are a great value for the $103 price tag. They seem to be very well made. My only complaint is that Alpine should include a grill with their speakers.
Review: No issues. Easy install Slim fit

*by W***H on 19 September 2025*

I installed Alpine car speakers in my Alfa Romeo GTV6, and the transformation was incredible. The sound quality is crisp, balanced, and powerful—exactly what you'd want in a classic sports car. Whether I’m cruising with the windows down or pushing through winding roads, the audio stays clear and immersive. The bass is tight without being overwhelming, and the highs are sharp without distortion. Alpine’s build quality complements the GTV6’s vintage charm while adding a modern audio edge. If you're looking to upgrade your driving experience, this setup is a perfect match.
