1 / 3
Reviewers consistently praise the Hertz DCX 87.3 for crisp highs, strong midrange and a clear improvement over many factory speakers; they often perform well driven by stock head units. Expect occasional fitment or tuning work—some installs needed minor modifications and a bass blocker or crossover to tame low-end overload on certain factory radios.
