FAQ

A crossover subwoofer is a subwoofer system designed to work with a crossover network, which directs low-frequency audio to the subwoofer while sending other frequencies to the appropriate speakers.

A crossover separates audio frequencies between speakers, helping route bass signals to the subwoofer and midrange or high-frequency signals to other speakers.

Many crossover subs can be integrated with factory stereos, but compatibility depends on the subwoofer’s inputs, the stereo’s outputs, and the vehicle’s audio system.

Passive crossover subs typically require an external amplifier, while powered models include a built-in amplifier. Check the product specifications to determine the setup required.

Use the subwoofer’s low-pass crossover control to select the highest frequency it will reproduce. Adjustments should be coordinated with the settings on the connected receiver or amplifier.
