  • Upgraded my Bronco with these speakers. Surprisingly good midrange and crisp highs. Easy to install and paired well with a 50W amp. Takes the audio to a whole new level.

  • They sound awesome in my Bronco. The highs are way clearer than the stock speakers, and I'm pleasantly surprised by how good the mids are. The bass might be a tad lacking, but overall, it's all good.
