Often the first, simplest and most sensible step to upgrading the audio experience in your vehicle is to swap out the factory cabin speakers with a quality pair of aftermarket replacement units such as these TS-1642Rs from Pioneer.
Once installed and adequately powered by an appropriate amplifier, these speakers will improve the clarity of your music, enabling you to make out details and sounds that were lost or muddied out by your factory speakers. With the capability of handling a steady 30 watts of RMS power at four ohms, rest assured that Pioneer had your long-term listening in mind when they designed the TS-1642Rs. Whether you're looking for crisp highs or punchy bass, these speakers are a great way to kick off your quest for the ultimate in-car listening experience.
