Car Audio System Upgrades in London, Welling, Chatham & Kent

Upgraded speakers produce clearer vocals, sharper highs, and stronger midrange compared to standard factory speakers. You’ll notice more detail in your music, richer sound quality, and the ability to play louder without distortion. Many of our customers in London, Welling, Chatham, and Kent say it feels like a live concert inside their car after a speaker upgrade.

While some factory radios can power aftermarket speakers, they typically lack the wattage needed for optimal performance. For the best clarity and volume, we recommend pairing new speakers with a dedicated amplifier. This ensures your speakers deliver their full potential.

The power you need depends on the type of speakers you choose. Most aftermarket speakers work best with an amplifier that matches their RMS (continuous power) rating. As a rule of thumb, the closer your amp’s power is to the speaker’s rating, the better and cleaner your sound will be.

If you want a noticeable improvement in sound quality, then yes—an amplifier is highly recommended. It supplies clean, powerful energy to your speakers and subwoofer, so you get distortion-free sound even at higher volumes. Amplifiers are essential for powering subwoofers and for anyone who loves listening to music at its best.

• Coaxial speakers (also called full-range speakers) combine the woofer and tweeter in one unit, making them easier to install and more affordable.

• Component speakers separate the woofer, tweeter, and crossover for superior sound quality, improved staging, and better control of different frequencies. If you’re after premium sound in London or Kent, component speakers are the best choice.

The difficulty depends on your vehicle and the equipment being installed. Some cars require more complex wiring or custom fitting, especially for amplifiers and subwoofers. At Autossential, our professional installers handle everything neatly and securely, so you don’t need to worry about DIY risks or messy wiring.

No — fitting aftermarket speakers, amplifiers, or subwoofers will not void your warranty unless the installation directly causes damage.
