Throughout the years of building bluetooth boomboxes, @nizzyamps has come up with a list of parts that are good to start with.  He is our resident guru on the electronics and has an awesome business retrofiring antique radios and building boomboxes.  Here is a beginning list.

Ammo Can:

50 mm ammo can https://amzn.to/2QnSSgx

Amplifier Boards:

The Dayton KAB series is all plug in play, which makes it the easiest board for beginners to use. I went ahead and posted the links to the adapter boards as well.  Not all of these are necessary, but you can take a look, as it is easy to add if you want it.  So you can easily get started on a project.

KAB Battery Extension Board: http://bit.ly/30HuLyh

Aux, Power and Volume Control: http://bit.ly/2M9DpSZ

18650 Batteries for the extension board: http://bit.ly/2GfNr0Y

USB Charging Board: http://bit.ly/30JY1Ew

LED Package: http://bit.ly/2GXfbrT

The Tinysine is one of the more powerful amplifiers one can use.  It even allows for an external antenna which greatly increases the range.  This was tested by Nizzy Amps

External Antennas for the Tinysine Amplifers

Sma Antenna: http://bit.ly/2VNVVQc or https://amzn.to/2W5lMIH  

Sound Deadening Material

Dampener: https://amzn.to/2YKZAQP

Batteries

Many amplifiers will play louder if they can take more voltage.  So I listed both a 12v and 24v version.  These are Lipo which drastically reduces weight over SLA.  Make sure to check your amplifier to see what  voltage it can take. 

12v Lipo: https://amzn.to/2EHVhyn

24v Lipo: https://amzn.to/2Wo7wKk

Power Switch

You can use a bunch of different power switches as long as they are rated for your battery.  Just make sure they are not a momentary switch, those will not work.  Having said that here are some of our favorites.

12v led Power Switch: https://amzn.to/30I0z6f

Power Jack:

This is used if you want to charge your battery while keeping it inside your boombox.  Keep in mind, the KAB board comes with this in it's multifunction kit.  But something like the tinysine, witht he talentcell battery, this is useful.

2.1 Power Jack: http://bit.ly/2M8w9GQ

Speakers

There are a ton of choices here.  The number one rookie mistake is to go with cheap speakers.  Please do not do that.  You are building this to make it sound good.  And by and large, the more you spend on the speaker, the better sound quality.  This is not always the case, but a good rule of thumb.  Listed are a few we have used and are happy with.

4" Kickers: https://amzn.to/2Ev4YzW

4" Polk Audio: https://amzn.to/2Mbx6yc

4" Kicker: https://amzn.to/2Ex0PLX

4" Kicker Marine: https://amzn.to/30G3ZGy - these do better holding up to water

Paracord

This isn't necessary, but if wrapped around the handle, it can prevent the handle from rattling.

I have a couple of questions. I have tried the KAB series boards, mostly the KAB250 v3. I have also used their battery board and Aux/Volume/usb board.

A couple of problems I have encountered which are hum if I use the Aux/Volume/usb board but if i simply use the seperate volume control and auxillary input I dont get any hum. I note the Kirby had this problem. Does anyone know if there is a proper work around, Dayton dont seem to be able to give me an answer on this.

Also if I use the battery board the charging LED doesnt work. I have tried this with 2 different battery boards and 3 different ampilifier boards.  Has anyone else had this problem.

I know the boards are versions of the Wondom boards but they are no help either. 

Thanks

Interesting.  I use the AB boards quite frequently and haven't had the hum.  Although, I must admit I usually use the 2x15.  I recently built a friend an Ammo Boombox that used the KAB2x15, the usb board and the volume.  I know Kirby had an issue with the first version, but I thought that was fixed in V2, but I don't know about V3.  Is it just the USB board when the aux cable is plugged in?  When does the noise emit?  Is it when something is plugged in and no music?

On another note, I haven't ever used the led's so I can't speak to that.  But I'll ask around to a few guys I know that have used them.

I use those kab250 boards all the time, the charging led only comes on when it's powered up, if you look at the board it's actually charging, but the indicator doesn't light up unless you power the system on.

Now that is valuable information.  I wouldn't have even thought about that.
