Upgrades for drivers who want better sound and smarter connectivity than the factory system offers. How we choose these picks.
Swapping a factory stereo for a double-DIN touchscreen unit is the most direct way to add wired or wireless CarPlay/Android Auto to a car that never had it.
Factory speakers are usually the weakest link in a car's audio — a component set (separate tweeters and woofers) is the upgrade most drivers notice the most.
A compact powered subwoofer adds real low-end bass without the box-in-the-trunk footprint of a traditional sub, since the amplifier is built in.
Once you're running upgraded speakers (and especially a subwoofer), a dedicated amplifier delivers cleaner power at higher volume than a head unit driving speakers on its own.
The cheapest way to add Bluetooth audio and hands-free calling to an older car — plugs into the 12V outlet and broadcasts to an open FM station.
Not strictly — a factory head unit can power modest speaker upgrades directly. But an amplifier delivers cleaner power at higher volumes and becomes worth it once you're adding a subwoofer or want to avoid distortion when cranked up.
Only cars with a factory double-DIN-sized dash opening, which is common on many trucks, SUVs, and aftermarket-friendly models. Many newer cars use integrated or non-standard dash openings that need a specific dash-kit adapter — check your dash opening size before buying.
