Materials:
Speakers 2 pcs. (I took two oval 3 gdsh 8 Ω)
Amplifier (I have a KIT kit on the K174UN20 chip)
Battery: battery, battery, power supply.
Case: any (I took a cardboard box)
Switch
(optional) Mesh for speakers: metal, fabric (I have a knitted mesh)
Signal cable (you can make an audio connector)
Wire or bolts or just glue-to fasten speakers
We will prepare the case: we will make holes for the speakers, the switch.Audio cable / connector
Then we try on the speakers in place. If they normally fit, then solder the wires to them (more truly, so that they easily reach the amplifier) and glue the mesh to them.
AMPLIFIER
We install the amplifier and the battery / accumulator / power socket (DO NOT ATTACH THE SCOTTLE! I HAVE come to OPEN IT AND MAKE IT ADHESIVE, THERE. THERE WAS QUICKLY ANNOUNCED AT THE SCAPE)
If you have a battery, do not forget to connect it before assembling the case (THROUGH THE SWITCH!)
Body assembly
After fixing the amplifier and the SWITCH we fix both speakers (photo of one speaker)
And we assemble the case (I still decorated it by gluing paper meters from Leroy Merlin in the corners))

Bye everyone, I wish you good luck homemade!)))
