Depending on the impedances of the speakers and the minimum that the amplifier can take you will have to wire a rotary switch as series or parallel connection for the "both" option, the inside and outside connections could just be direct. You can get switches made for this purpose from Japanese vehicles that have front and back spkr options. |

Yes that is the wirewound pots that I am talking about. You may not need to have the pots at all if you choose the speaker connections and switch unit correctly and you are not too worried about individual control of speaker volume inside and outside. |

The switches I am talking about can be found in wreckers yards from old buses and suchlike. If you connect too many speakers in parallel onto amplifier outputs you will blow the output transistors so make sure you have the information on impedances before doing this. |

Thanks zwerty, will go to wrecking yards in the morning for a browse |
