Hello Keith,
You can purchase the Dome and Mural from the author of the CD/DVD.
It is best to wait for the dome before cutting out the hole, some people have told me that the measurement in the instructions is a too large.
Always use the original Rowe Ami amplifier, cross overs and speakers.
If you are using a hideway as a donor jukebox we can supply you with the correct speakers and cross overs to suit your amplifier and supply you will plugs, sockets and made up looms.
Regards
Alan
