Ammo Can BlueTooth Speaker Build

In this video I will show you how to build your very on BlueTooth speaker using a military ammo can. You can use this speaker with a phone, Android or Apple, iPad or any other tablet or play music right from your computer.
I realized after posting the video that I left out a short segment on connecting the amp. It's very simple. At 28:13 I am showing a wiring harness and it ends with a positive and negative wire with a female connector on each. The power cord to the Bluetooth/amp module plugs in there.

Thank you for the great video and parts list !

[@MikeSmith-mj8tp]

By far the best and simplest build video I have come across so far. Great build! I love it!

[@brentspepper2087]

Thank you

[@guy260476]

I built one using the instructions you gave along with the parts list and I have to say it sounds very good thank you for sharing

[@brentspepper2087]

I'm glad it worked well for you. Thanks and enjoy.

I like your build, very inspirational. You must have family in South Africa with your clothing choice. Very nice.

[@caseymoto]

nice job.. i have been debating adding a port to my ammo boomboxes... i like how you have the 12v socket as the charger, mine has a separate plug to charge.. didn't realize the cigarette lighter port could be used for outgoing power and also incoming to charge...

What would be a good plastic size ammo box to get for that amp you have in the build and plye 6.5. 1/2 150watt marine speaker?

[@kojakdurham]

Nice, clean build. I'm going to do a couple of videos on mine. It's not as clean inside as yours, though. I used larger speakers in a larger can for more frequency response out of the woofers. Call me a bass-head. :)

[@brentspepper2087]

Thanks for the kind words.

[@MrDegsy69]

Kojak Durham rocking good news! That is the way i am going as i am rescuing the bass, treble and crossover from a pair of bookshelf speakers with damaged cabinets. I think this ammo box idea is totally mint as it is a far more rugged and practical design for field use and actually gains character with a few knocks and scratches. Really looking forward to gigging this at one of our hobo changba parties next summer! 😂😂😂

[@austinwillets5115]

Looks really cool I'm making one in a different style and i was just curious how long the battery usually will last you per charge?

[@brentspepper2087]

Honestly I have never ran it so long that I ran the battery down to test it. I've probably ran it 4-5 house at the most and the battery was fine.

[@johnlewis6899]

Brent, I followed your plan and love the sound from this. I have begun getting a popping noise from the speakers after 45 to 75 minutes of continuous playing. I'm at a loss as to what can be causing this. Any ideas or suggestions? Thanks in advance.

[@brentspepper2087]

John Lewis check all you wiring connections. Could be temperature related since it starts after it has played a while.

[@Psalms144_1_2]

Hello, love your build, I'm ordering the parts now, but what size battery do you have Amp Hours?

[@brentspepper2087]

Here is a link to the battery I used. smile.amazon.com/dp/B007ROUG42/?coliid=I3EYS9YD1T8SFI&colid=1LFKUAVHIC2E8&psc=1&ref_=lv_ov_lig_dp_it

[@MrDegsy69]

This definitely looks a good practical build that will be rugged in the field unlike the poncey commercial off the shelf ones. Just a few things though when clamping the ammo box in the workmate try putting some offcut wood noggins inside the box that fit closely and you can clamp it more tightly without fear of crushing it. Also i did not like the way you did the cut outs on the stencil print side of the box as it looks messy on the finished item. Surely the plain side would have been better?

[@brentspepper2087]

Actually I wanted the stencil side to be showing on the front. I've done a a few using new cans that had no stenciling on them.

How is the amp connected to the power with the excess two connectors? I’m building this right now and am at a standstill. Thanks and the video is extremely helpful!

[@brentspepper2087]

Sorry, I left a short clip out of the video. At 28:13 I am showing a wiring harness and it ends with a positive and negative wire with a female connector on each. The power cord to the Bluetooth/amp module plugs in there.

[@SpencerBud09]

The wire itself, or did you add connectors to the ends of them?

[@brentspepper2087]

Around the 3:30 mark I talk about the Bluetooth/amp and that you can get it with a power supply. I cut the DC cord of the power supply and connected it to my wiring harness. You can also buy a package of the male connectors and make your own connector to connect to your wiring harness.

[@austindifelice7065]

Where did you find the charger itself with the male connection on it, that seems to be the only parts I can't find. Thanks!

[@brentspepper2087]

I made it. I bought a small 12v charger and cut the alligator clips off and connected the cigarette lighter plug onto it.

[@jdreichenbach]

What speakers were used in this video on the can you assembled? The link to parts says Pyle but those were in the can you had previously built. Do the Pyles sound as good?

[@brentspepper2087]

I've put the Pyles in 3 boxes and for the money, they sound great.

Can you snap a picture of the wiring harness going to your AMP? I have read through the comments, but am a visual guy. I don’t want to mess this thing up, and have to wait for another AMP to come in the mail. Stationed overseas and mail can sometimes lag… Thanks much in advance!!

[@brentspepper2087]

I don't think I can reply with a photo in the comments section.

[@guitargodjake]

3 questions. How long will the battery last? I noticed the amp you linked was 50 watt but the speakers 180 watt, is that right/does that cause any issues? To allow the 12v to be used to charge did you have to wore it a different way?

[@brentspepper2087]

Honestly, I haven't timed it to see how long the battery will last. The speakers being a higher wattage than the amp is not an issue. if it were the other way around then that would be a problem.

[@MrDegsy69]

Jake Evans The only real problem with using speakers with a higher power rating than the op amp is that they may sound a little understated due to the amp being underpowered in relation to them. They will not neccesarily draw more current than the op amp can provide but will definitely lack gain when you crank it up to 11.

[@shadowort2287]

180W peak. Those are no more than 50w rms. You pair speakers to amps using rms wattage not peak

[@brentspepper2087]

Before you ask about wiring up the amp, it is in the description above. It's really very simple.

[@600gmc]

Can you go into more detail on powering the amp? Did you splice in before or after the transformer?

[@brentspepper2087]

There is no transformer. You have the battery that goes to the switch, and from the switch you have a wire that is connected to the amp.

[@600gmc]

@@brentspepper2087 I was talking about the amp itself. The amp has a wall plug in that goes to a small transformer with a smaller wire the plugs into the amp. In this case, I would assume that you splice the wiring from the t12 VDC battery into the wire past the transformer, correct?

[@brentspepper2087]

@@600gmc I understand. This has been asked before. Some how that portion of the video wasn't included. I simply added a male adapter plug to a wire coming from the switch and going to the amp. The transformer than came with the amp is not used.

What would be a good black plastic ammo box that this speaker PLMR60W dimensions is 7.4 x 7.6 x 7.1 inches so what should the product dimensions on the ammo be that fit the speakers on the same side ?

[@brentspepper2087]

Unless it is really thick plastic, I wouldn't go with plastic. You could try one of the plastic cases that Harbor Freight has. They aren't ammo boxes, but more like a Pelican case.

Would you need a diode in order to use this while charging?

[@brentspepper2087]

No you wouldn't. I've used it while charging many times.

[@charlesgoldmacher254]

2 questions. First question. How do you do the power cord from the outlet to the cigarette lighter adapter. (What do you use?) Second as everyone else has asked about connecting the amp for power. I saw the video and it shows the wires to connect the amp but not what wire you used from the amp to connect to it. Very confusing both of these questions. Otherwise very informative and I'm looking to build it this weekend but need these answered

[@brentspepper2087]

The amp instructions are in the video description above. I guess it was left out because it is so simple. I'm not sure what you mean by "The outlet to the cigarette lighter adapter". It's just a 12 volt charger with clips for negative and positive. Cut the clips off and wire them into a cigarette plug.

[@nathanhoffman5]

Did you install any inline fuses?

[@deputyk9114]

Does a mid range speaker even need a port? I thought ports were for sub woofers.

[@brentspepper2087]

I'm not sure if you could get by without a port or not. Because of the confined space and the amount that these speakers move, I opted to put a port in it.

You keep saying the amp wiring issue is so simple, but you are leaving something out. Are cutting and modifying the power cord that came with the amplifier? How are you transitioning to the actual connection on the amp unit? This is a great video except for this one very important detail that ultimately make the entire video useless.
