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.

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.
