Why Choose This Product?

The R1525X2 brings the tweeter and midrange woofer together, while its integrated crossover directs frequencies to the appropriate driver. That built-in network avoids the need for a separate crossover component. With 40W RMS power handling and 4-ohm impedance, these speakers are rated for use with typical head-unit power or modest amplification.

Installation & Compatibility Notes

Check your vehicle’s speaker opening and available mounting depth before purchase. The listed mounting depth is 1.93" (49 mm). Confirm that the location accommodates a 5.25-inch speaker and that your head unit or amplifier supports a 4-ohm load.
