    New Build...not a gun

    So I built my own portable bluetooth speaker out of an Ammo Can. Its a 50 cal SAW box. It uses a Dayton 50w x 2 channel amp with bluetooth and aux in. Speakers are 4" JL Audio C1. Grills are custom made from computer cooling fan grills. I lined the front and back of the box with 3/4" plywood and then used car sound deadening material to coat the entire inside. Sounds awesome!

    That's pretty slick. Perfect for the rest of the decor.

    Wife tells me I should build them and sell them on Etsy.

    The truth I that you can buy a portable Bluetooth speaker much cheaper. It won't look as badass or sound as good...but all in this was over $200 to build. I could use more inexpensive components, but then you sacrifice sound quality. There are dudes selling similar things for like $400 so I guess there is a market. That is what inspired me to build my own. I knew I wanted one when I saw them but wasn't going to drop $400 on one.

    I was thinking of trying out a mono setup for my next build. With the speakers being so close you really aren't experiencing the stereo separation anyway...but with a larger speaker, I could get better bass response.

    I have to admit, though, that this sounds darn good for a pair of 4" coaxial speakers.

    Anyway, thank you for the kind words. I am enjoying it.

    There are a few things I would do different next time around. I wouldn't use that mounting plate on the back but drill my own holes for the leds and accessories. I definitely would put the volume knob and power switch on the front with the aux in and power on the side. I did it this way because the plate was an accessory with the Amp that simplified wiring. After building one now I know that the wiring was simple anyway...it's just a matter of drilling out uour own template for the switches and lights.

    If any of you would like to build your own There is a kit on partsnexpress to make this project with a plastic ammo can. You can then add anything else you would need. I didn't use the speakers with the kit but it was just as cheap to buy the kit. If you use a metal can you will also need to get a Bluetooth antenna.

    Cool man. Let me know if you need any help. I will try to point you in the right direction. FYI, a saw box lined with 3/4" plywood will be around 0.3 cubic ft. That may help with your sub choice.

    Also Parts express has been awesome as I am planning another build already.

    This time around I am going to do a mono setup with a 6.5" mid driver with a titanium dome tweeter crossed over at 3-4000 hz. The speakers are so close on the 4" speakers that you really can't tell the stereo separation anyway. I think having a single 6" driver will make bass response even better.

    Don't get me wrong, those 4" JLs really do sing and sound really good. Using coaxials simplify the build though.

    So I posted this build on facebook and a bunch of people are now contacting me wanting me to build one for them....so my wife might be right. I might do this as a side hustle.

    If I would do this what should I call this? I was thinking "The !BOOM! Box" ???

    I like can rather than box. No !!!’s military-like stenciling in flat or matte yellow.

    Thanks. That rig is inspiring. If you do go into production be sure to save one for me to purchase. I gave all my Bluetooth speakers to my nieces so need one they only get after I’m gone.
