Today I initially intended to just make a Bluetooth speaker from an old surround speaker I had laying around. I wanted a speaker to take to the beach that sounded better than the little inexpensive guys you get. And I didn't want to buy something expensive that I was constantly worried about down there. Anyway, it dawned on me this morning heading down to the beach, instead of hauling both my guitar and speaker down there, why not just throw the speakers in my guitar? lol

Step 1: First Step - Not Your Main Guitar!

Get out your old guitar or get a cheapie out of the paper, you probably don't want to use your Martin:-).

Step 2: Pick Some Speakers

Find yourself some speakers. I had some old 4" speakers that seem to sound good. As long as they fit and match the ohms in the unit shouldn't be a problem.

Step 3: Amp

I bought this little guy off eBay for thirteen dollars. I am more than impressed with it. It is not only Bluetooth, but plays SD cards and USB flash drives, AND charges your power source through the mini USB in the front! Which allows everything to be tucked away all neatly inside.

Step 4: Power Supply

You can get these little units anywhere. I am sure you have seen them. I actually grabbed mine from my old deadbolt keypad lock I had replaced. But an electronics store should carry these for a couple bucks.

Step 5: Cut Holes and Place Unit and Speakers

Here I just positioned the speakers where they fit and sound best and the unit where it would be out of the way (because I still plan on playing this guitar). Also, because the guitar is meant for sound it is perfect for this sort of thing, so placement of the speakers will make somewhat of a difference.

Step 6: Wire It Up

Pretty simple here, just left speaker to the left speaker port on the unit. Right speaker to the right port on the unit and the power supply to the power port. And then re-string your guitar and your good to go! I just need to find the speaker covers now.lol.
Nice! i have an old guitar in my attic(not worth but a couple bucks) that would be perfect if you dont mind me copying!? lol
<p>This is fantastic! I have an old guitar that got the side smashed in by a couple of careless kids, but since it was a gift from my father, who has passed away, I can't bring myself to give it up, but have been planning on thinning the body and hanging it as a wall decoration. With bluetooth capabilities, that just sweetens the whole thing!</p>
<p>How long does the AA batteries last? And whats my best bet on batteries for extended time? Great idea though creating this myself right now!</p>
I actually changed from the AA's to two batteries from my old Samsung note cell phone. I just soldered the two together and taped them up for a nice rechargeable package. And these last forever. I kept it playing for a couple of days just to see
<p>These modules are now easily getable for about 3 dollars right here:</p><p>http://www.ebay.com/itm/USB-MP3-Decoder-Decoding-Board-Remote-Music-Speaker-Wireless-Audio-Module-/231424587245?pt=LH_DefaultDomain_0&amp;hash=item35e1faf5ed</p>
<p>Hey FokkoP Do u need anything else beside a power supply and the modules because i been trying to wire my own guitar with no success. Everyone i go too has no idea how to do a project like this and experts say i need a amp please help i want to be done with this project already!</p>
<p>i have this amp -&gt; </p><p><a href="http://www.banggood.com/Bluetooth-MP3-WMA-Decoder-Board-12V-Wireless-Audio-Module-USB-TF-Radio-p-937208.html" rel="nofollow">http://www.banggood.com/Bluetooth-MP3-WMA-Decoder-...</a></p><p>can anybody recommend what speakers I should use for best quality?</p>
I see that you have a 12v unit there. mine is only a 5v so I had to take that into consideration. with yours I would assume you would have several more options because of the power. that 12v unit was meant to be used for an automobile from what I have read. so I would start in the auto sound arena of speakers(best guess). also, you might want to look at the remote control hobby section on eBay for you power supply. I have been looking at doing another build and the LiPo battery pack and LiPo battery balance charger seem to be a great fit for this kind of stuff. anyone else have any thoughts on this?
<p>Almost all of these decoder boards have liniar regulators on them which just steps the voltage down to 5v, no need to worry about your power supply as long as it's more than 5v and less than 30v</p>
<p>how do you wire it? this is my first time doing something like this so its not simple i have the same amp as u but i only have one audio port.</p>
<p>Hi</p><p>I am using one of these in a solar power bank for camping and I have been worried about wiring the speakers as the sites said not amplified speakers and I was going to wire them to some old car speakers are you getting good sound from yours and could you please show the circuit for your set up?</p>
<p>Hi</p><p>I ended up using some usb powered speakers great sound thanks for advice I watched your clip and I also attached the antenna and ran a small wire around the inside so the radio works as well</p>
hi there. yes i am getting quite good sound from these speakers which are just car speakers. you can check out the video i made on youtube for more of an idea on what they sound like.... Bluetooth Guitar Speaker Build: http://youtu.be/_yQPx2icO9M
<p>I like this! I'm going to re-create it with some spins, updates to follow...</p>
thanks! look forward to seeing what you come up with...
I haven't found the Bluetooth amp on eBay. Do you have more information about this unit?
<p>I am not sure that they can be used to amplify but rather a place for all the sources to come from. To connect it to the speakers I think you would need an amplifier board to connect to the speaker first (this will also draw current from the batteries so you may want to rethink your power source) the amp itself is fairly cheap you can find them with the key word &quot;amplifier board&quot; on deal extream</p>
it is an amplifier as well or it wouldn't work I don't think
and it is quite loud.
<p>sorry.. forgot to put the link... http://www.dx.com/s/bluetooth+decoder</p>
OK, found the module:<br><br>http://www.banggood.com/Bluetooth-MP3-WMA-Decoder-Board-12V-Wireless-Audio-Module-USB-TF-Radio-p-937208.html
<p>Found one similar to soouncool's </p><p><a href="http://www.ebay.com/itm/Digital-5v-Amplifier-Bluetooth-Call-functions-mp3-decoder-board-FM-Radio-usb-AUX-/231031678333" rel="nofollow">http://www.ebay.com/itm/Digital-5v-Amplifier-Bluetooth-Call-functions-mp3-decoder-board-FM-Radio-usb-AUX-/231031678333</a></p>
yup, that's it
can you make a video playing with it and just to see how it sounds. please and thank you :)
<p>Wow that turned very cool looking. Thanks for sharing!</p>
Great idea beautifully executed. :)
:-) didnt take long actually
Very nice Idea
thanks!
