Introduction: Boombox Hi-Fi
This is a Hi-Fi boombox that I built from old speakers
2x midrange speaker
2x 3 way crossover
old jeans or other
battery or power supply
Step 1: Build
first you need to build a box to hold the speakers, the audio amplifier, the crossovers and the batteries.
I built the box with a special wood for the Hi-Fi speakers.
as speakers I used 3 different types of speakers, two 3w and 8ohm tweeters, two 5w and 8ohm subwoofers and then two 5w and 8ohm mid-range speakers.
I mounted the two midranges on the side panels, while the two tweeters and the two subwoofers on the front panel.
Step 2: Wiring
First we need to connect the audio amplifier to the speakers and to the battery I used a 15 + 15w 9v amplifier. I to connect it to the power supply I added a switch to switch from the power supply from the DC jack to the batteries and vice versa. as batteries to power the amplifier I chose two 18650 4.7v 3000mAh in series or alternatively an external 9v 1A power supply
Step 3: Finishes
