Product Description
Match APBMW X4E front coaxials with two APBMW S8-4 underseat woofers to add body and punch without changing the OEM look. Bass lines gain presence and the overall balance feels fuller.
Note: Underseat woofers perform on factory power, but deliver their best depth when driven by an external amplifier.
