Most vehicles come with basic stereo systems that include the normal head units and 4 speakers. Choosing to upgrade beyond that could prove to be more complex than just replacing the old component when you buy a new one.

If the car didn’t originally come with an amp from the factory, this will entail you wiring it to power. Doing this will mean that you have to get a type of 1-amp fuse.

Why do I Need a Car Stereo Amp Fuse?

If the new amp has an inbuilt fuse, then you have a good advantage.

However, the fuse shields the amplifier itself and this does not extend to other wirings in the car. The most important function of the fuse is to prevent a possible short-circuit in the car.

Be careful when fixing a power cable for the new amplifier as any short circuit that isn’t fused can lead to significant damage to the car. It can get worse to the point that the shorted-out amplifier wire will lead to a fire.

In the event that you were careful during installation, just driving around even on a smooth road can cause your car fittings to jostle and bump a lot.

It is normal for wires to shift and abrade each other from time to time and this can lead to a lot of spoilage in your car if not properly addressed. This is exactly why the amp fuse is essentially a vital part of amplifier wiring.

Connecting the Amplifier to Power

You might find it hard to resist the urge to hook up the new amplifier to an existing amp fuse box, especially as the fuse distribution block is located beneath the dash.

Obviously, it’s easier than just running a new power wire through the battery. It is important that you resist any urge to use this bypass.

You need to avoid any connection of the amplifier to the box in the car and never link an existing fuse or circuit. This is because your amplifier is going to exert amperage more than the wire in the box is configured to carry.

Doing this will mean that you are risking a catastrophic lapse even if it means swapping the small fuse for the big one or using an empty aperture in the fuse box.

This issue is tied to the way the fuses function and the power issue they are configured to handle. In basic terms, the fuse is the component that is configured to fail for every other thing in the amp circuit to be protected.

If the component housed in the amp circuit happens to draw much amperage, if the short circuit turns to an immediate amperage spike then the fuse is likely to blow thereby interrupting the circuit.

In the absence of any fuse or the failure of a fuse to cut the circuit as a result of arcing, the other components will likely be spoilt or possibly a fire may occur.

The Right Fuse Location

Car amplifiers are known to draw so much amperage, making the mistake of wiring it improperly can lead to overloaded power cables and electrical fires. This is why it is good to run the power wire separately from the battery down to the amplifier.

If you own multiple amplifiers, you can decide to run a power wire with the distribution block. Make sure the power wire is thick and good enough to carry the current drawn from all the amplifiers that get fed from it.

In the event of having issues with any of the amps, or the amp power wire short circuits, the effect could be catastrophic and damaging to your car. One of the outcomes is that the car can go up in flames or possible explosion of the battery.

This is why it is necessary for you to install the in-line fuse stationed between the car battery and power cable. It is also the reason you should put the fuse right at the car battery in the stead of the amp.

Placing the fuse on the amp will lead to a lack of protection from the fuse in the event of the cable shorting out somewhere.

The Right Fuse Size

Right after getting the best location for the fuse, it is also ideal to make use of the appropriate size fuse. When you have to use a very small fuse, it is likely to blow when the amp is on normal operation.

Additionally, If the fuse is too big, it could lead to unit failure or even electrical fire. When the amp has an inbuilt fuse, then the inline vehicle amp fuse can be a bit larger than normal.

For example, you may wish to use a twenty-five or thirty amplifier line fuse if the amp has a good inbuilt twenty-amp fuse.

When there are two amps with inbuilt glass fuses of 20 amps then you have to add the figures together to find out the actual size for the inline fuse. This will give you a bit of room without having to expose the car to a not-too pleasant situation.

Most amplifiers don’t come with inbuilt fuses and in this case, you will have to crosscheck the ratings of the amplifier to ascertain the appropriate size for the inline car amplifier fuse.

If it is an amp without an inbuilt fuse or multiple amplifiers that have no inbuilt fuses, you need to consider using the fused block for distribution.

According to the protection module of the fuse during short circuits of the power wire, the fused block protects the other amplifiers and related units in the event of the failure of one of the amps.

Type of Fuse

Some amps that have inbuilt fuses make use of some automotive fuses. They are the same kind of fuses for the car which are used in other areas of the car and stereo components like the head unit also use similar fuses.

If you install the in-line fuse, it is possible to put the same fuse which is pre-installed in the holder which connects the in-line fuse with the amplifier power line.

Another option is using the in-line fuse. This entails using fuse holders which will have you the in-line wire getting installed with a power wire. This means that the fuse will be in the form of the translucent or clear plastic tube holding a normal barrel fuse

Irrespective of the fuse in use, it is important to choose a good fuse holder which meets the fuse rating you plan to install. If you ascertain that you have to use a thirty-amplifier inline fuse, try not to install any fuse holder below the rating of 25 amps.

Now that you know the right fuse size, here are a few tips on how to get the best out of your amplifier.

Change Your Car Speaker

In most practical cases, speakers are the last thing the manufacturer worries about when building and designing your car.

Most Factory audio systems have improved in recent years, however many of the premium systems use inexpensive speakers and amplifiers that do not produce the highest sound in the stereo.

You can also make a huge difference in the sound quality of your system when you install a good set of speakers. You will hear louder bass and clarity, and you may see details that you have not heard in a song you have known for long.

The backup speaker gives you the maximum value for your money and is a good step towards a better sound.

Choose a Higher Quality in Your Music File

Yes, it is possible to store mp3 files in the music player when there is more compression. This sounds good when listening to headphones.

However, you are likely to lose low and high-frequency information if you compress the music, as well as some features that make the track interesting.

Skip the Digital-to-Analog Converter Built-in to Your Music Player

Digital-to-analog converters have the task of converting the digital information – 0 and 1 – into analog signals. In some cases, the player is your smartphone.

The internal DAC is usually good enough for listening with headphones, but without the performance, you get with the more sophisticated DAC found on much better car radios lately.

If you connect the iPod or cell phone to stereo using the USB cord, you can adjust the DAC on your device. This depends largely on the stereo system. Make sure you check the information on the stereo.

Use Clay Material

Reducing road vibration and noise, Hushmat, Dynamat, and other soundproof products enhance the sound of your system in two ways.

First, the door trim is not the ideal place for speakers – the metal vibrates during music playback, which turns out to have an effect on the audio quality.

When the speakers are attached to the door trim, these vibrations are moistened and a more balanced platform for the speakers is made that is more like a wooden barrier than home speakers.

Secondly, have you noticed that your system usually sounds very good at speeds of 40 km/h, but it becomes a little difficult when you reach 60km/h.

The noise on the road usually covers the lesser frequencies first, this way your system will sound too bright if you change it at high speed. Soundproofing material lowers your car’s noise level.

So you do not have to play as much music as you drive before you will hear more music details and your amplifier does not need to work too hard too. And that is good.

Add Automatic Boosters

No matter the effectiveness of the speakers, you can get the best performance when you add more energy (of course, in its technical characteristics).

There is a big difference in 50 watts of peak power for every channel and produced by the car audio and RMS 50 watts from outboard amplifiers.

Separate amplifiers provide cleaner performance than any vehicle stereo and make a difference in audio quality day and night. Your system usually sounds nice, whether you are listening to Mahler at a normal level or the Metallica at 11. Amplifiers are very important to get a good sound in the car.

Add the Processor of the Signal or EQ

The Car interior raises some serious sound quality problems. Plastic and glass surfaces reflect crazy sounds like carpets and seat covers. If you add a sub-woofer to the mixer, you will get a significant frequency connection in most interior cars.

These tips will make your track pop bass or fall to a height, causing ear damage.

Most vehicle receivers offer high, medium and bass control – used for global adjustments, but not to be used for rearranging problem areas. You need an EQ to eliminate this surge, whether it is installed on the receiver or a processor installed on your dashboard or near the amplifier.

The sticky equalizer allows you to adjust the frequency response with multiple points to smooth out these peaks in the system. With the parametric equalizer, you can change the width and the center of each equalizer area so it will be easier for you to focus on the problem area.

The sound processor helps you eliminate peak frequencies and enhance bass. Some may include a normal microphone to analyze the acoustics of your car.

Adjust Your Equalizer to Get the Best Audio

Using the right EQ can optimize a little and listen a lot, but it’s fun. Start everything “flat” and arrange for 1 or 2 things at once. You will find what is lacking in audio and what is too much. You will immediately use the equalizer to select it correctly.

Create Better Fields

If you are building a closed subwoofer box, check to see if it is properly sealed. Air leaks significantly affect the performance of your replacement. If you have to use a carrying case, make sure you have the right cable.

You can spoil the liner that is designed to use a closed box by moving it firmly in a closed container.

It is also important to construct a compartment with the right interior space for the submarine you have chosen. Failure to do so can lead to poor performance. You can avoid all these problems by buying an artificial cabinet that works with the subwoofer.

The Crossover and Sound System Improvement

Many built-in receivers include frequency filters that work with the speaker outputs and pre-amps. If it is a submarine, use a high filter to detach deep bass from the car’s speakers.

You get cleaner volumes, especially if you operate them with power integrated into the receiver.

Or if the sub sounds loud, and the bass usually sounds like it is emerging from behind. If you experiment while increasing or reducing your low filter crossover, you can adjust the bass-forward with the music.

Some amplifiers have sound filters that can remove very deep bass under the human hearing area. Turn on – your amplifier and submarine will work cleaner without this ultrasonic sediment.

In addition, the compression needed to create music files which can cause your customers to make silent transmission sounds. Your filter can eliminate or minimize the noise.

Adjust Your Amplifier Correctly

Some people think that controlling the amplification of their new amp will control the volume. Of course, they submerge it which leads to bad things. The control adjusts the input signal input to the amplifier.

If you activate it too high, you will hear a serious evil turn.

The aim is to change the volume control of your receiver around 3/4 to the maximum volume, and then increase the amplifier gain until there’s distortion. Pull it and you’re sure to be.

Each amplifier manufacturer has specific suggestions. Therefore, read in your manual how best to adjust the gain of your new amp.

Remember to get the appropriate wire size, one-amp fuse and get a professional to guide you if totally necessary. Check here to see how to adjust your car amp for the best sound.
