  • Alpine speakers
Great speaker great bass
Reviewed in the United States on January 17, 2026 by penske89

  • Easy upgrade with great sound
I replaced the factory speakers in my 1995 Ford Bronco with these Alpine S2-S65 speakers and couldn’t be happier. Installation was easy and straightforward, and they fit perfectly without any issues. The sound quality is a huge upgrade—clear, balanced, and much fuller than the old speakers. Highs are crisp, mids are solid, and overall volume is impressive without distortion. If you’re looking for an easy speaker upgrade that delivers excellent sound quality, these are a great choice. Highly recommended. ... show more

  • Alpine speakers s series the best.
Get these speakers or any other size that works for you. I put these in my truck ten years ago and they still sound great. Good base and mid as well. I put the 6 1/2 in my Bronco and they perform great. Getting the four inch for the dash, can't wait. I give them all a 10+ rating.

I bought me some nice kicker speakers first they were very good too, But the Alpine speakers were even better. I recommend them to anybody who enjoys loud music

  • Great sounding speakers
The Alpine s65 are nice addition to their entry level line. They can handle a ton of power and will add great highs and mids to your set up. One not is you will need to purchase the grills separately if your set up has them exposed.
