Pioneer's TS-A878 2-way speakers are an excellent replacement for your factory 3-1/2" speakers. Their woofers are constructed from Carbon-Graphite blended IMPP (Injection Molded Polypropylene) for an exceptionally lightweight, rigid cone. A 1" PEI (polyetherimide) semi-dome tweeter tops them off with vibrant highs.
