Small cars, crowded cabs and side-by-sides still deserve real low end. These 6.5 inch subwoofers from Sundown Audio and Crossfire Car Audio fit spaces where a 10 or 12 never could, including under-seat boxes, kick panels and powersports pods. Choose from the Crossfire C5-6.5, Sundown SA-Classic, U-Series v.1, X-Series v.2 and the Sundown Powersports PSE-6.5, with D2 and D4 options in several models.
A 6.5 inch woofer will not shake the mirrors like an 18, but it adds the low bass that most door speakers can't reproduce. That makes it a smart fit for regular cab trucks, small coupes, motorcycles and UTVs, and for anyone who wants subtle, clean bass fill without giving up the trunk. Several small subs in a shared box can also add up to impressive output in a compact footprint.
Small subs usually want small sealed enclosures, so check the manual for the exact recommended volume. A compact monoblock, or a bridged pair of channels on a multichannel amp rated for the load, can drive one or two of these; match the RMS rating and the final impedance. In powersports rigs, choose a protected mounting location and secure the wiring against vibration and water.
Want more punch in a small footprint? Step up to 8 inch subwoofers, or explore the full Sundown Audio subwoofers lineup. Because 6.5 inch subwoofers draw modest current, a compact unit from our amplifiers collection and a matched wiring kit usually cover the job. For every other size, start at the main subwoofers page.
