Editor's Review:

The Alpine SWR-1223D 12″ Car Subwoofer is capable of handling up to 600 watts RMS. It is the fourth generation of Type R subwoofer that Alpine has released and produces the cleanest and most efficient sound ever. It features new structural updates such as a more shallow mounting depth for smaller mounting spaces, an improved magnet design that produces up to 20% more force for louder and cleaner sound, and improved airflow to keep the subwoofer's temperature low to avoid overheating. The Alpine SWR-1223D lives up to Alpine's reputation for producing quality and incredible sound.
