A 7-band graphic equalizer designed for car audio setups, this gives you hands-on control over frequency ranges that a head unit's built-in EQ typically can't match.

Designed to mount 6.5" or 6.75" aftermarket speakers into factory door locations that weren't built for them, these adapters save you from cutting or modifying your door panels during a speaker swap.

Something feels off with those numbers — a Bluetooth FM transmitter with a USB-C charger typically retails for $15 to $30, so the $130 list price listed here doesn't reflect real-world pricing. At $15, you're paying a reasonable amount for a device that lets you stream audio from your phone to your car's stereo via an open FM frequency, which is useful if your car lacks Bluetooth or aux input.

A single-DIN head unit that fits most standard car stereos and adds Bluetooth calling and audio streaming without requiring a full double-DIN cutout, so it works in vehicles where space is limited. Buy Now at Newegg

A speaker crossover capacitor filters out low frequencies before they reach a tweeter, which helps protect the driver and improve clarity in a two-way speaker setup. At $10, there's no discount here, but it's a straightforward way to add basic crossover filtering if you're doing a DIY car audio install. Buy Now at Best Buy
