It doesn't matter how good your source is; all the music you hear comes through your speakers. A good set of Pioneer TS-A1675R speakers can make a world of difference, especially if you are used to basic factory sound. While the receiver may have all the shiny features, you should always start with the best car stereo speakers. These three-element speakers feature an integrated tweeter, midrange, and woofer in the same speaker assembly. By using a multi-driver array, Pioneer is able to keep each element working efficiently. It can handle up to 300 Watts of peak power, and sustain up to 50 Watts. Enjoy the full rich sound of all three drivers working in harmony.
