Building a home Hi-Fi using 12V car sopund components Answered
Many years ago I used to have big sound systems in my cars. I grew out of this but am left with the parts, i.e. speakers and radios and amps.
I would like to build a hi-fi system using these parts. I’ll need to build enclosures for the speakers and radio and amps. No problem.
My problem revolves around how do I power this setup? Using a charged car 12V battery is the simplest option and will give the cleanest sound, but that will have the problem of maintaining the battery using suitable charging mechanisms. The other option is to build or buy some kind of 12V power supply that can run from a household 220V AC power socket. The problem with this is, that the power supply will need to be able to handle large currents, to the tune of 90 Amps!!
How can this be done?
