IN PHASE Speakers

Discover our range of IN PHASE Speakers

In Phase speakers are built to refresh tired factory systems with clearer treble and tighter mid-bass, or to anchor a fuller upgrade with a dedicated sub. The range typically covers common sizes for doors and parcel shelves, along with component sets that separate the tweeter from the mid-bass driver for more flexible placement. If you are replacing standard paper cones, even a like-for-like size can bring a noticeable lift in clarity and dynamics.

Choosing is about fit and priorities. Coaxial speakers are the simplest swap, with a tweeter mounted on the main driver so they drop into the factory location with minimal fuss. Component sets add an external crossover and separate tweeters, useful if you want to position highs higher on the door or A-pillar. If you listen loudly, pair door speakers with a modest amplifier for more control. For extra weight below, add an In Phase sub in the boot and keep bass duties off the door drivers.

Installation basics make a big difference. Use adapter rings to mount speakers securely, apply foam gaskets for a good seal and add a little sound-deadening round the aperture to calm panel buzz. Keep polarity consistent, positive to positive and negative to negative, so left and right work together. If the factory head unit remains, look for speakers with sensible sensitivity so they play happily from lower power, then consider an amp later if you want more headroom.

When buying at Currys, check the exact size your car accepts, whether you need component or coaxial, and if you plan to add a subwoofer or amplifier. A simple two-door refresh can be done in an afternoon with the right adapters and tools. Pricing varies by retailer and region.

Are component speakers better than coaxials?

Components can image more precisely because you place tweeters higher, but coaxials are easier to fit and suit straightforward upgrades.

Will new speakers work with my factory head unit?

Yes, if you choose suitable sizes and sensitivity. An external amplifier can be added later for more volume and control.

How do I check speaker polarity?

Use the markings on the terminals or the harness colours. If in doubt, a quick battery pop test on a loose speaker can confirm cone direction.

Do I need an amplifier for a subwoofer?

Yes. A dedicated amplifier, or an active sub with a built-in amp, is required to drive a subwoofer properly.
