Anyone upgrading their car’s speakers knows the drivers themselves are only half the story. Without proper treatment behind the door card, even expensive speakers can end up sounding flat, rattly or underwhelming.
Dynamat is aiming to simplify that process with its new Pro Speaker Kit, now available in the UK through distributor Celsus ICE, available to buy online or from your nearest specialist dealer.
Designed as an all-in-one sound treatment package for a pair of doors, the kit combines sound deadening and acoustic enhancement materials intended to help both factory-fit and aftermarket speakers perform at their best.
And the good news is it can all be installed yourself in a few hours at a weekend. Here's how:
Inside the box are two 18in square sheets of Dynamat Xtreme, two back-wave closed-cell foam pads, and four speaker ring strips – enough to treat two speakers up to 10in in size. According to the company, the combination will reduce panel vibration, absorb rear soundwave reflections and improve the seal between the speaker and the door card.
That last point is often overlooked, but sealing the gap between the speaker basket and the trim panel can make a noticeable difference. Rather than letting sound spill around inside the door cavity, the foam rings help direct more output into the cabin – often improving perceived mid-bass punch and vocal clarity without changing the speakers themselves.

As the video shows, installation is relatively straightforward. The process involves applying the Dynamat Xtreme sheets to the inner door skin, placing the back-wave foam behind the speaker to absorb reflections, then fitting the supplied ring strips around the speaker itself before refitting the trim panel.
At £79.99, this is a low-cost upgrade for anyone wanting better sound without replacing major components. In many cases, treating the doors properly can deliver a bigger improvement than simply swapping speakers alone – particularly in modern vehicles where thin metal skins and lightweight trim can introduce unwanted resonance. Or if you’re buying speakers, grab a Pro Speaker Kit to make sure you get the best out of them.
