Quick Review:

The Alpine SWR-823D 8″ subwoofer in an impressive sub that packs a punch. It handles up to 350 watts RMS and 900 watts peak. It features an extra long woofer cone made from Kevlar treated pulp to move massive amounts of air for an 8″ subwoofer. To top it off, the new Type R subs such as the Alpine SWR-823D are designed with a shallower mounting depth and frame so you can fit them in tighter spaces. And like all of Alpine's products, it's made from quality materials and built to perform. The Alpine SWR-823D is an excellent 8″ car subwoofer.
