Connecting a power supply to a car amplifier should be fairly easy. Some receivers and integrated amps have an impedance switch to change the impedance (usually, 4 /8 ohms). This is because some home speakers are rated at 4 ohms .
Av receivers transports you have two bookshelf or audio connection. This simplified drawing shows the traditional stereo receiver. I'll explain why in another pair of the receiver to read here straightforward process is.
Can I use 8 ohm speakers with a car amp?
If you’re looking for an inexpensive sound system for a home theater then you might want to consider using your car speakers. You could also try temporarily connecting the power supply to a different AC power source and see if you still get the noise. As class D car amps are around 85% efficient and A/B amps are around 65% or so efficient we can use that to estimate the total current an amp would need. In this article, I’ll explain how to connect a car amp to a home stereo with clear diagrams anyone can understand. I’ll also show you all the little things you need to know before you try so you avoid disappointment & headaches.
Yes, you can but first, you must connect the transmitter to the amplifier or receiver, the transmitter will then send audio wirelessly using RF. Your amp comes with a jack, you will, therefore, plug the opposite end of the speaker wire into the matching jack. You will then invest in a harnessed wire that splits into 2 wires on 1 end, and then proceed to plug the wire clips into the positive and negative terminals. If your speakers are lower than 8ohms then you can wire them in a series. The information about the ohms of your speakers can be found at the back of the speaker.
Buy or build a speaker enclosure
However, this may not give you the highest SPL and sound quality as speakers wired in series draw more power to reach a higher SPL. Most car speakers are coaxial/full-range speakers (2-way or 3-way). 3-way drivers have a bass and midrange woofer and a tweeter. I’m not really sure what the issue is with the Procharger, but yes I would definitely try connecting an additional ground between the amplifier and other things it’s connected to. Sometimes that can eliminate the difference in ground potential that causes noise.
Tuning a bass reflex, especially for beginners is incredibly complex and beyond the scope of this article. I will thus skip it for this time as there are different types of ported enclosures you can build. There are also several online guides you can learn from if this is something that tickles your fancy. I might also prepare a dedicated article for this, so be on the lookout for it. To find out which enclosure type is best suited for your project, calculate the EBP . To do this, divide the driver’s free-air resonant frequency by its electrical Q rating (Fs/Qes).

Car speakers are also typically 2-way speakers with smaller woofers and tweeters. While some of you may be looking to power a couple of home theater speakers by your car's stock audio system, most of you are probably looking for a better sound option. While a car stereo may be a great match for the spare bedroom at your parent's house, it probably won't cut it in a grown up living room. It’s a great idea, because they may work fine even though they’re not top of the line speakers. It’s not likely the same speakers would sound as good in your car, because they won’t be as big or powerful and you’ll be sitting much closer to the car speakers. Also if you use car speakers in a home theater you may want to consider changing the angle or direction of the speakers.
The assembly process involves the use of the wires from your car stereo, so for a flawless experience, we recommend that you unwind the wires before installing the amplifier. The next step is to put aside the RCA cables from the power cables to prevent them from interfering with the signal. To connect a receiver to a car amp it should have front, rear, and sub preouts. These preouts will then be connected to the respective line-level inputs on the amplifiers using RCA cables. Connect your speakers to the head unit’s speaker outputs using the white and gray wires for the front left and right speakers. The green and purple wires will run to the rear left and right speakers.

The next step is to unplug your amplifier and speakers to stop the flow of electricity. Also, if possible get the speakers in an enclosure as building one can be a hassle if you have not done it before. Alternatively, get a prefab enclosure that will be best suited for your drivers. Using an inverse relationship, we can reverse this formula to calculate the net volume . This net volume is what we are most interested in as it takes into account the air displaced by materials in the box including the driver, bracing, and dampening materials .
This will allow the amp’s circuitry to automatically turn on when it detects a 12-volt+ input from the power supply. The speakers’ impedance should match that of an amplifier. Car stereo amps have a nominal impedance of about 4 ohms to match the speakers. However, some car speakers are component split and have different drivers for different frequency ranges.
You’ll need to be sure to avoid connecting a speaker impedance that’s too low to a home stereo amp or receiver. Doing so causes it to try to produce more electrical current than it’s designed for. This causes overheating and potentially permanent damage to your electronics.
Some subwoofers produce more volume for the same amount of power. This is actually a standard specification used to compare speakers and the official name isspeaker sensitivity. In other words, the sensitivity of a speaker describes the volume output it produces for a given amount of power, in decibels .
You can find these with a crossover built-in for under $30. Important to note is that if you are going to tape them off, then you will have to do that on the individual wires, thus prevent the wires from touching anything else. Unfortunately, noise is a problem with car amps despite them being designed to prevent it.
