Shop Car Speaker Upgrades by Type
Browse the range by speaker type to find the right car speaker upgrade for your vehicle.
Coaxial Speaker Upgrades
Coaxial speaker upgrades combine tweeter and woofer in one unit, offering a simple factory replacement and straightforward installation process. Browse our full range of Car Speakers to find a compatible upgrade for your setup.
Component Speaker Upgrades
Component speaker upgrades separate the tweeter and woofer with an external crossover for better sound and power handling. They lift the sound stage closer to ear level, making them the better choice if you want the sharpest detail from your front doors. Explore our Car Tweeters range to complete the upgrade and achieve optimal performance.
Why Choose a Car Speaker Upgrade?
Upgrading your factory speakers is one of the most effective ways to improve your sound system and overall driving experience. Here's why.
Better Sound Quality
Factory speakers often use thin paper cones and small magnets, limiting clarity and performance at higher volumes. A speaker upgrade for your car is typically the first step to improve sound quality before replacing the head unit or adding an amplifier.
Stronger Mid-Bass
Upgraded speakers use improved cone materials and stronger surrounds to produce deeper, more controlled mid-bass. Paired with a dedicated amplifier they can produce enough bass from the front doors to reduce the need for a subwoofer.
Complete Fitting Kit
Vehicle-specific kits include the required mounting adapters, plug-and-play wiring harness, and related equipment for a straightforward installation, in contrast to standalone speakers, which may require additional brackets and wiring modifications.
Factory Fit Installation
Supplied adapters match factory mounting points, so speakers fit without cutting or drilling. This preserves the finish, ideal for leased vehicles and resale value. Professional fitting protects the door wiring and trim, and comes with a warranty on parts and labour.
FAQs about Car Speaker Upgrades
Will a car speaker upgrade actually improve my sound?
Will a car speaker upgrade actually improve my sound?
Yes. Replacing factory paper cone speakers typically delivers clearer vocals, sharper detail and stronger mid‑bass across your existing system.
Do I need an amplifier for a speaker upgrade?
Do I need an amplifier for a speaker upgrade?
Many upgrades, especially high‑sensitivity models, work well with factory radios or low‑powered stereos. Pairing them with Car Amplifiers adds clarity and headroom, but it is not required to hear the difference.
How much does a car speaker upgrade cost?
How much does a car speaker upgrade cost?
Vehicle-specific kits on this page run from £19.99 to £745.49, with most sitting between £50 and £200. A typical front door pair with the adapters and wiring included costs around £60. Prices rise with cone material, power handling and whether the kit includes separate tweeters.
Can I fit a car speaker upgrade myself?
Can I fit a car speaker upgrade myself?
Yes, in most cases. The kits are plug and play, so the factory connector unplugs and the new speaker plugs in, and the supplied speaker adapters bolt onto the existing mounting points. Expect around one to two hours for a front door pair, mostly spent removing and refitting the door card.
