Ikea items used: 12 pieces of white EKBY ÖSTEN shelves (79cm x 19cm x 1.8cm)
I used 12 pieces of IKEA white EKBY ÖSTEN shelves to make the pair of speakers and the center unit to house the old car stereo system and PC power supply.
I cut the EKBY shelves to match the width of the car stereo. I used 2 full EKBY shelves to hold the cut pieces together. Same for the speakers, I cut the EKBY shelves to size, cut holes to fit the speaker drivers.
I drilled holes on the edge of cut pieces and the 2 shelves and fastened them with wood dowels and glue. Same process for the speakers.
This unit was assembled to house the car stereo on top and PC power below. I used a plastic polystyrene sheet as backing for the center unit. I ran a power cord to connect the car stereo to the PC power supply.
Final assembled IKEA Stereo System with shelving.
