Want a little more from your hidden speaker system? This is it! We have developed the UNDERCOVERII with an 8" woofer and 2 Piezo tweeters in each box. This system can be mounted in many of the same locations as the regular UNDERCOVER. With the 8" woofer in UNDERCOVERII you get a much fuller deeper sound. These are a great addition to our Concours series radios with their 250 watt capacity. Sold as (pair). Measure 11"W x 12.5"D x 3"H
