The common automotive scrap yard is a land of plenty for the enterprising hacker., where many items that would be prohibitively expensive elsewhere can often be had for a song. This isn’t just limited to strictly automotive parts either, as the modern vehicle is full of all kinds of hardware. [Nikita] managed to salvage a pair of audio amplifiers from an old Volvo, and put them to good use. It’s a great idea if you’re looking for cheap audio hardware!
The amplifiers are from a Volvo 760 made in 1984. There’s one rated at 40 watts per channel, and a smaller device rated at 25 watts per channel – likely to drive the front and rear speakers from separate amps. The amplifiers take 12 volts nominally, as one would expect. After some initial testing with a car battery and unsticking old relays, things began to crackle into life.
With the hardware now functioning, it was simply a case of bolting the amplifiers into a frame, hooking them up to a converted ATX power supply, and wiring up some connectors for speakers and audio input. With a few bits and pieces invested, [Nikita] now has a good quality amplifier to run audio in the workshop.
