Buying Guide

Match impedance to your amplifier

Choose a subwoofer with an impedance (2Ω or 4Ω) that matches your amplifier or wiring plan to avoid power loss or damage

Check RMS and peak power ratings

Compare RMS (continuous) and peak wattage to ensure the sub will handle sustained output; several budget subs list both RMS and higher peak values

Pick the right driver size and enclosure type

Eight- and ten-inch drivers fit tight spaces and shallow mounts, while 12-inch drivers typically move more air—match size to available space and bass goals

Consider dual voice coil options

Dual voice coil (DVC) subs give flexible wiring choices for different impedance loads, useful for matching amplifiers in multi-sub setups

Inspect mounting depth and cone construction

Shallow-mount designs and reinforced cones improve fit and longevity in vehicles with limited depth or high vibration environments
