Product notes

What each pick is best at

Best overall speaker upgrade

Pioneer TS-G1710F 17cm 280w Dual Cone Coaxial Speakers with Grills

A coaxial option for making a factory system clearer without changing the whole car.

What we like

Lowest listed price in this comparison at £28.50, £0.39 below Kenwood KFC-S1766 Stage Sound.
The only pick here listing 280W power, giving it a clear difference from the other 5 options.
The coaxial layout keeps the drivers together, which is usually the simpler replacement route for a factory door or shelf speaker.

What we don't like

Unlike some alternatives, the listing does not show a comparable power figure, so matching it to the rest of the system takes more checking.
The fixed coaxial layout offers less placement flexibility than a component set, and the speaker size and depth still need measuring.

Buying guide

What to check before ordering

Measure the original speaker opening and mounting depth. Compare RMS power and impedance with the existing stereo or planned amplifier, and check whether grilles, tweeters or crossovers are included.

Use the model number as the final reference. Retailer images and prices can change, and vehicle fitment should be confirmed for the exact make, model and year.
