Buying Guide

Match box size to driver

Confirm the enclosure supports your woofer diameter (6x9, 8, 10, 12) to ensure proper fit and acoustic performance

Choose sealed vs angled

Sealed enclosures give tighter bass and fit well in trunks, while angled boxes help speaker aiming in truck doors or rear decks

Check construction material

MDF panels and carpeted finishes resist vibration and provide a stiffer enclosure than thin plastics

Measure mounting footprint

Verify external dimensions and mounting hole placement for your vehicle to avoid fitment issues in trucks or sedans

Look for pairs and packaging

Buying two-box packs simplifies stereo installations for rear 6x9s and often includes matched angled designs for symmetry
