The 8Y A3 RS3 B&O / Sonos upgrade kit we have developed is genuinely second to none, 14 speakers and the dreadful factory subwoofer can be upgraded without a wire cut, hole drilled, no glue, no damage in any way.
This is what we do ! We source, design and manufacture the required parts to give our customers the best experience possible.
With waterguards for the front & rear this complete kit is £149.99
If you’d like to upgrade to the deluxe version we will include 20 sheets of sound-deadening and 4 large sheets of acoustic foam we can do that for £200 inc VAT.
