Designed as a great replacement for most OEM speaker applications, the S Series speaker systems offer great performance at a great price. We even improved our tweeters to make sure that even the most discerning listener is satisfied. This range offers a complete line-up specifically sized for OEM drop-in replacement of 2.75”, 3.5”, 4", 4”x6”, 5.25", 6.5", 6.75”, 4”x10”, 6”x8” and 6"x9". We have even added a hard to find 2.75” full range speaker that fits many Chrysler applications - making our S-series one of the most complete lines available. With so many sizes offered in this coaxial and component range, these speakers make an excellent choice for Autosound enthusiasts who seek true value along with ease of installation.
