When I first started installing, my house stereo was a car stereo, powered with a 7-band eq-amp combo. There are several ways you can power your setup. The best is a filtered power supply like they use in car audio display racks you see in the stores. These are specifically designed for this purpose. But they are not cheap! ($100+). Just remember your "power formula" for deciding how much amperage you need. Use the chart at: https://www.the12volt.com/ohm/page2.asp to calculate for "Current. Using the maximum power output of your stereo (or amplifier if you have a backstrapped unit on a portable boombox that unplugs). WARNING!! If you are using home speakers connected to your head unit or amp, be very careful! Home speakers are generally rated at 4 ohms, as opposed to autosound speakers, which are 8 ohms! This could cause your  amp/stereo to overheat, causing it to clip.. Watch the volume levels.
