Buying guide

What to check before ordering

Start with the space available, then compare RMS power, enclosure type and input options. A factory stereo may need high-level inputs or a line-out converter, while a passive subwoofer needs a separate amplifier.

Use the model number as the final reference. Retailer images and prices can change, and vehicle fitment should be confirmed for the exact make, model and year.
