Alpine's SWR-1522D 15" subwoofer delivers impact bass that you can hear and feel. Alpine has taken the best features from its previous SWR Series subs and added the hottest technology for ground-pounding power and superb accuracy.

Kicker's 40CWR154 15” subwoofer comes equipped with a tough, polypropylene cone that stays rigid during intense play sessions so you hear accurate bass. A custom-designed back and top plate give the woofer plenty of room to travel, while the durable rubber surround helps to control cone movement.
