I decided to use my old desktop stereo speakers & incorporate them in my charging station, so i can play my music with more bass. (A lot better than cellphone's loudspeaker) + can be used as an extremely loud speakerphone or an extremely loud alarm clock.

Step 1: Get Donor Speakers

Get old desktop speakers or any pair of powered speakers. Small enough to fit in to the box that you have chosen.

Step 2: Disassemble

Carefully remove the drivers, transformer and the circuit and any other components.

Step 3: What We Need. Bare Essentials.

After taking out all the components, cut of excess wires (AC mains & Line in) & make them short. and remove other stuff that you don't feel is useful. (like knobs and screws)

Step 4: Time to Add the Amplifier, Transformer & Drivers in the Charging Station.

OK, from where did the charging station come from? Here. My earlier project. Please watch.

Step 5: Connect the Components

The picture explains it i think. I know it doesn't look safe, but it is. I was worried about the transformer melting the plastic. I was relieved that it doesn't heat.

Step 6: Place the Components Inside.

Tape any exposed wires with electrical insulating tape & carefully place the amplifier along with speakers.

Step 7: Make Speaker Grill

Take any reference and make holes to make it look like a speaker grill.

Step 8: Mark on Both Sides.

Or if you want to go creative, go ahead and make any design you like.

Step 9: Mark the Dots. (again, Use Your Creativity)

Step 10: Make Holes With Soldering Iron

Make holes on the dots with the soldering iron. (Do not inhale any resulting fumes)

Step 11: Clean It Up a Bit.

It could get messy, shave of excess plastic with blade, knife or a steel ruler.

Step 12: Place the Lid.

Step 13: Done!

Done! Now it can be used to play your favorite tunes, radio, or as a speakerphone or put it on high volume and make sure you wake up in the morning!

Note: I could have put the volume controls on the outside if i wanted, but i want to make it look clean. So I kept the vol (on the amplifier) at 80% & set my desired volume through the Phone.
