I have been (without luck) looking for a beach-proof boombox with an iPod dock.
Aside from a jobsite radio; like a Bosch or Milwaukee, there’s nothing I would kick around the sand. But, these tend to be on the hefty side.So, I decided to build my own. This project went thru several versions. The image attached to this project shows only the two speaker interation. I eventually decided to add a woofer; this iteration is shown in the video link.
Design Goals:
1. Portable
2. Battery Powered and Rechargable
3. Beach/Sand/Waterproof – PVC provides that. And I’m no wizard with building wood boxes.
4. Bawls – Wanted something that could pump out the jams. 25 Watts seems like plenty with the 4″ speakers.
Tools / Materials / Parts & Pieces:
2′ length of 4″ PVC pipe
2 x 4″ PVC 90 degree elbows.
3/4 Plywood board
3 x 4″ drain grates
4″ PVC Tee
Weatherproof Electrical Outlet Cover – Makes a great dock for iPod Nano, Mini and Classic. iPod Touch’s are a little too long for this.
Sure 2x25w Class-D Amplifier - Has enough oomph for this project and is small.
DC 5V 9V 12V Portable Rechargeable CCTV Li-ion battery - Found on eBay. Has 5V USB output for recharging devices AND 12V 2.1mm output for powering the amp.
Audio/Sync Cable for iPhone/iPod (Apple Dock Connector to USB / 3.5mm Audio) – Allows for input into the amplifier and will also charge the iPod off the battery.
2 x Dayton Audio RS100-4 4″ Reference Full-Range Driver 4 Ohm - These sound great paired with the amp above.
1 x Dayton Audio ND105-4 4″ Aluminum Cone Midbass Driver
2 x Passive Crossovers - Found on eBay.
Video of Completed Project !
Ultimately this turned out to be a little too heavy and I opted to put all the guts into a 16" toolbox. This is shown in the attached images.

In the later Toolbox version, I used a sealed-lead acid battery. I just open the box when I want to charge it.
Concerning your speakers, is your mid-bass airspace separate from your full range or do all three share the same space?
Can we see a video of your final version?
The red/black wires come from the AMP and plug into the Passive Crossovers. The speakers attach to the outputs of the Crossovers.
In this build, one crossover is connected to the mid and bass speaker.
The other crossover is just connected to the second mid.
