Audio amplifiers are generally used by musicians, bands, artists, and performers who need to demonstrate and project their talents in front of various crowds (anywhere from one to millions). Depending on the number of the audience or attendees, and considering the venue’s size and structure, different types, sizes, design and capabilities of audio amplifiers should be utilized. For an acoustic guitar artist playing in the local pub with a maximum seating capacity of 30 guests, an average stereo amplifier will do. On the other hand, a show band performing in a venue as big as a stadium would need several amplifiers, or a combination of it, ranging from power amplifiers, tube amplifiers and even digital amplifiers – all of which contribute to the total satisfaction of the audience.
Amplifiers can also be used for home, car, or even garage use (for those people who have the passion for music and are members of start-up bands out there – Rock on!). Several products are available in the market for amplifiers dedicated to home and personal use (stereo amplifiers, car amplifiers, etc.). They come in different colors, designs, and even purchasing cost. For the people who would like to have an audio amplifier, but don’t have enough resources to obtain one, or for those people who just want to be adventurous and experiment on building one from scratch, read the rest of the article to see how you can make and design your own set of audio amplifiers.
1. Step 1. Purchase the following items from your nearby hardware/music equipment store:
- Speaker Amp
- Pre Amp
- Speaker Wire
- 1.5-inch Thick Birch Plywood
- Paint (Color of your choice)
2. Cut 4 pieces of the Birch plywood into 16x10 inches with the handsaw. Cut another 2 pieces from the plywood into 16x16 inches in height and width.
3. Connect all 16x10 inch plywood boards to form a square. Use the nails strategically to fasten the boards tightly together.
4. Use the router to make a hole in one of the 16x16 inch board. This board will be your front panel. Position the speaker flat on the front panel and outline the circular frame. Cut that circular shape out with the saw.
5. Slice out a rectangular hole several inches on top of the circular frame you just cut in step 4. This will be for the Pre Amp and controls, so make it a point to measure and fit the actual Pre Amp before executing.
6. Use the drill you purchased and make holes in the front panel and the front of the square frame you finished in step 2. Screw them together and then skim the speaker wires all the way through the speaker hole.
7. Snuggly fit the speaker and the Pre Amp into their respective places and reinforce them with the screws to make sure that they are well-fastened in their places.
8. Keep in mind that to get the best out of your audio amplifier, you have to use thick wires. The thicker the wires used, the better the amplifier performance. At the very least, use 16-guage speaker wires to hook up the speaker to the Pre Amp.
9. Finally, complete the casing of the frame by using screws on the other 16 x16 inch board to the back of your very own amplifier. You can paint and design your finished amplifier according to your own preference.
10. Plug your audio amplifier, play your instrument, and Rock On!
