Hi all, I have an antique cable radio speaker box which I would like to make into a bluetooth speaker. The existing speaker and internals are useless, so basically it's just a wooden box. The old speaker was 8" round and about 4" deep. I was looking to use the following to make it into a bluetooth speaker. Dayton Audio KAB-250v4 2 x 50W Class D Audio Amplifier Board with Bluetooth 5.0Dayton Audio KAB-FC Function Cables Package for Bluetooth Amplifier Boards19.5V DC 3.33A AC Power Supply Adapter with 2.1 x 5.5mm Tip + PlugDayton Audio RS100-4 4" Reference Full-Range Driver 4 Ohm |

| If it's a full range driver it will require no crossover with that amplifier. |

Even if I am using two of the same driver? Sorry for questioning but don't want to make any mistakes. Is there anything else that you would suggest is needed? |

and if I decide to use a woofer along with the full range driver, would I then need a crossover? If so what would you suggest? Is there any point to having a woofer along with the full range, or not really needed? |

Just run 1 full range driver per amplifier channel. If you intend to go with a sub too I'd recommend a 2.1 amplifier with crossover built in already. Keeps things simple on your part.
A 2.1 amplifier will run 1 sub + 2 full range drivers (stereo + sub). The sub driver would ideally need it's own separate chamber inside the box though.

Ok. How do I connect the 19.5V DC 3.33A AC Power Supply Adapter with 2.1 x 5.5mm Tip + Plug to the amplifier card? |

| Normally it just plugs straight into the board via a barrel connector. If your amp has bare wire power inputs then just chop the barrel connector off the amp and wire it in via bare wires. |

Thanks for the suggestion. The hole is actually 9", so I was thinking of attaching the two 4" on two strips of wood, top and bottom, then attach the strips across the hole. Can't figure out how to share a picture of it that I have on my google photos. I looked at the link for the 8" dual concentric but that weighs 9lbs, which I think is too much for the purpose. |

| Ok I'm out 🤣. This has to be a wind up! |

Not a wind up. Just someone who knows next to nothing about speakers. |

| Mounting them on 2 bits of wood won't work unless they're sealed to the box (air tight all the way around the driver circumstance). |

Ok. I really need to try and get pics of what it is I am working with. |
