DCC Sound Fitting Guides

Find our recommended speaker for the most popular models below. Where possible we also provide a link to a fitting guide. This page will constantly evolve, if a new model is released we'll add it, and if a new better speaker is released we will update our recommendation.

To keep things simple. We recommend speakers which most people will be able to fit themselves at home, no major or irreversible work is required, but you may need to make minor alterations, such as unscrewing fans, this will be listed under the notes column if relevant.

To help you understand the different types of speaker we sell, we have a guide here.

And to help you understand the different ways to wire them up we have a guide here.
