If you have a spare car amplifier that is not getting used sitting in the bottom shelf of your garage, then you might as well make use of it and connect it to your home stereo. If your home stereo has two speakers, then you can hook up a car amp and add an additional subwoofer just for bass. Now you will need to power on the car amp so you will need to obtain a 12 volts. You can't connect a car amp to a wall plug as that is 240 volts and will blow up the amp straight away. An old computer power supply would work the best for this and it is the cheapest option. You can salvage this out of an old PC or you can purchase one from Ebay. The best way to be certain that it will be sufficient enough is by matching the watts, for example is your amp is 500 watts a PSU that is 500 watts will work fine in most cases.
Connect the power to the car amp:
1) Jumper the green wire to the black wire on the ATX connector on the PSU. This will bypass it to make it turn on.
2) Gather all the yellow and black wire together. Pair them up in colors and twist them together.
3) Connect the red power wire that goes into the 12 volt terminal on the amp together with all of the yellow wires.
4) Connect the black ground wire that goes into the amp to all of the black wire on the PSU.

5) You will need to trick the amp to come on. So connect the blue remote wire to the 12 volt terminal using a small piece of wire.
Connect the car amp to the home stereo:
1) Look on the back of your home stereo. There should be a pair of RCA sockets that are labelled as 'Output' or 'Line Out'.
2) Connect your RCA cables into the 'Input' on the car amp and the other end into the Output socket on the home stereo matching the colours.
3) All you need to do now is connect a subwoofer to the speaker terminals on the amp using wire.
