Overbuilt? More like built just right Kicker designed their CompR subs for people who love to hear strong bass in their music. The CompR 43CWR84 8 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 during a heavy workout. This sub uses extensive venting in its heavy steel basket to shrug off heat, so you can count on reliable performance. Say hello to system flexibility This Kicker CompR will handle up to 300 watts RMS so make sure you have an amplifier that'll do it justice. Its dual 4-ohm voice coils give you more wiring options when setting up your system, and this versatile sub works well in sealed or ported enclosures. To drive this single subwoofer, we recommend a mono amplifier rated between 225 and 450 watts RMS at 2 ohms.
