1 review for Alpine S-S50 S-Series 5-1/4″ 2-way car speakers

  1. Josh

    Alpine gives a ton of value with the S-series line of speakers available in co-ax and components. These speakers utilize design elements that trickle down from their R-Series and X-series speakers. For speaker around $100, no one comes close to the value that these speakers bring. Whether your running off your head unit or an amp these speakers perform great. The silk tweeters are smooth and the mid bass is great. Don’t forget to sound deaden to get the most out of your speakers!
