As long as the necessary steps and precautions are taken, you should have no trouble powering your subwoofer and enjoying crystal-clear audio. You’ll need a 12V 3A power transformer, a 12V DC regulated power supply, a base amplifier, and a speaker. Make sure you select components that are suitable for use with a 12V amplifier. Start by plugging an RCA audio cable into the “Sub Out” or “Pre Out” jack on your stereo. Make sure whichever jack you use is compatible with your cables and amplifier.
No, it is not recommended to wire a car stereo to a house outlet. Even if you use an adapter to convert the voltage, the safety concerns and risks are too great. Getting the right wires and connectors is essential when you are wiring your car amplifier. The gauge of the wires should be around 14 or 16 AWG and have at least 0. Also, the wires should be long enough to reach both speakers.

Most automotive subwoofers are designed to operate at 12 volts, which is insufficient compared to the power supply in your home outlets. Connect all of the wires in the proper locations and tighten all of the connections. So, if you want to use your automobile subwoofer at home, make sure you pay attention to all of the connections.
In that case, you can try a simple RCA cable ground loop isolator which often solves it. For home use, choose a power supply with a DC output from 12V to 13.8V, with 12V being perfectly fine to use. When shopping most of the higher-current supplies you’ll see are 12V anyhow. You can estimate how much electrical current (amperage, “amps”) your amp will draw based on its maximum power given in watts RMS.
How can I make a car amplifier at home?
Note that you shouldn’t try to get the cheapest you find because they can negatively affect sound quality. You can estimate amp current based on the maximum RMS power of the amp. Don’t use “peak” or “maximum” watts as these don’t reflect the actual continuous power a car amp puts out. In order to figure out how big of a DC power supply you need, you might want to calculate roughly the amount of current your amp will draw at full power. Once we know that, we can take into account wasted power that all amps use up and come up with a fairly accurate number. You will also need to use the appropriate wiring technique to ensure that the speakers and subwoofer are getting the correct amount of power.
However, the truth is that’s only if you need a lot of power. As you have found the longest wire of your PSU, you will notice several wires in this longest cable. What you are about to do is, you will connect these wires to create a loop.
How to Power a Car Amplifier Using a Computer Power Supply
Audio transformers are typically composed of copper wire windings around a steel or nickel-iron alloy core. Each core material transmits electromagnetic signals differently. Steel has a higher degree of hysteresis , making it better for lower frequency transfer. If you are just playing at home or want one for recording you can now have your very own real tube amp for very little money.
Provided the above criteria is met and you take heed of the recommended safety considerations, powering a 12-volt amp in your house is a relatively simple procedure.. It is much more advisable to invest in a car-specific amp or to purchase an entirely new car subwoofer/amp combination. Fortunately, by using resistors or other current-limiting components, it is possible to control the flow of electricity based on the amounts of amps passing through the circuit. An amp, or an ampere, is a unit of measure for electricity that is equal to the amount of current flowing in a circuit.
Any type of electronic or electrical appliance is incomplete without the power supply unit. If there is no power supply unit, you cannot use your gadget or anything that you want to operate. But here, you will use a desktop PC power supply unit because it is cheap and easily available. For example, imagine investing around$40to customize your automobile subwoofer for home use when reasonably used house subwoofers are around$50?
You can use that amplifier and sound system at your home without any effort. So, there is no need to worry about losing your favorite sound system or amplifier. You wonder, can you pull out your car amplifier and sound system and play t in your home. There can be several different conditions where you may want to use your amplifier in your home.
In some cases, you may need to do a sound test to ensure the connections are proper. Car subwoofers may not be the best choice for home audio as they are usually smaller and are not designed to handle the same power as larger home subwoofers. Additionally, in order to get the full listening experience from car subwoofers, you may need a larger amplifier than you would for home audio. Next, connect the speaker wire from the output terminals of the amplifier to the input terminals of the subwoofer. It’s important to use the correct gauge of speaker wire for the job, as it will affect the sound quality.
Use max current rating of your power supply to choose your wire gauge. Its always better to get as big wire as you can connect to your power input that is as short as possible and then use longer wires to your speaker. With higher power amplifiers its good to also include fuse that is recommended with your power wire. Shown here are two examples of line level/RCA speaker level converters that work well for home receiver/amp to subwoofer use.
