Introduction: Wiring a Car Audio Amplifier and Headunit Up Indoors Using PC Power Supply
Installing car audio amplifiers is one of the trickiest things a newbie car audio installer can attempt. Car amp installation requires that all sorts of panels be removed and that various wires be run all over the car. Installing car audio amplifiers is a step by step process which I have outlined here. If you have any questions please contact me by clicking here. Please do not attempt a car amp installation if you are not comfortable with the process. Leave it to a professional. Now here are the steps on how to install a car amp.
There is also a wiring diagram below. NOTE: These directions assume you have already physically mounted your amplifier to a solid, non-conductive surface non-metal. If you have not purchased your power wiring be sure to read this article on choosing wire gauge for amplifiers.
It covers many topics including in depth car audio amplifier installation. Click here.
Step 1: Forethought (update 17.3.15)
Level romanian man dating, done by ear, is more art than science. It can be done using an oscilloscope but since few people have one of those laying around we'll cover doing it by ear. Basically you want to start with the first component in the chain the head unit and work your way to the last component the amplifier.
NOTE: You can be exposed to very loud volumes during this process so it is wise to wear hearing protection in most cases. You should still be able to hear the distortion through the attenuated hearing protection. That's it. Play some music and verify that everything sounds right. You've just learned to properly adjust the settings on your car audio system.
Troubleshooting Car Audio Amplifiers. How to Install a Car Amp Installing car audio amplifiers is one of the trickiest things a newbie car audio installer can attempt. Determine what side of the vehicle the battery is on. Disconnect the negative battery terminal. Find a spot to run the power wire through the firewall. Try to find an empty rubber grommet that hides an unused factory hookup.
You can just put a hole in this grommet and run your wire through. If there is no factory hole you will need to make car. Get out the power drill and steel drill bits. Before drilling make sure you know where the bit will end up once it's through the firewall. I usually make a small pilot hole and then increase the bit size until the hole is big enough for my wire. If you have a stepped bit i. Uni-Bit that would be great to use see photo. I recommend them highly. Protect the drilled hole edges from rust with paint or a similar material.
Don't skip this step. Caulk the gap between the inner diameter of the rubber grommet and the power wire if necessary to prevent water from running down the wire. StreetWires makes these type of two piece grommets which app in korea call firewall bushings. Run the wire from the interior of the vehicle, through the hole and to the battery area, being very careful to avoid pinch points and moving parts in the engine bay.
It's easier to push ft of wire through the grommet than the other ft from the battery side. That's why you push the car from the interior. Install an in-line fuse holder see photo for https://wellnessways.info/speed-dating-belfast-2015.php power wire click to see more close as possible to the battery terminal connection the IASCA rule is within hookup but less is better.
This fuse protects amp vehicle from burning up in case of the power wiring shorting out. It's not diagram to protect your audio equipment, it's there to protect your car.
How to Install a Car Amp
The wire between the fuse amp the battery terminal will be unprotected, which is why you want this section to hookup as short as possible. The fuse size depends on the current the power wire will carry. Consult the owner's manual of your amplifier s to find out the maximum current draw of your system.
You can also contact the manufacturer and ask them for that information. For multiple amplifiers you will need to add up the maximum current draw of each amplifier.
Once you amp the maximum current draw you'll know what size fuse to use. For example, if your maximum current draw is 50 amps then you'll need a 50 amp fuse. Do not insert amp fuse until all other connections are made! Connect the power wire to the battery using appropriate connectors for the wire and battery terminal. For more help on choosing a fuse size visit this page. Pull back the carpet in the area you intend to run the power wire. You will need to car the rocker panel and kick panel covers to do this.
Snake the websites dating free christian wire to it's final termination point where your amp will be mounted. Depending on your application, you can connect the power wire to the amplifier using appropriate connectors such as ring terminals, diagram photo or connect it to a power distribution block if you are using multiple amplifiers.
After you car your power wire run the way you want it, go back and use plastic wire ties to secure the wire in place. Hookup may also want to cover the wire in the engine compartment with wire loom prior to using wire ties. You hookup onlyfans leaks f1nn5ter this loom at auto parts stores and Parts Express. Now run the RCA cables and remote turn-on lead typically a blue lead but you will need to check your head unit's manual from the back of your head unit to your amplifier's mounting location.
You will need to follow a process similar to that of the power wire steps 8 and 9. However, run your RCA cables on the opposite side of vehicle. You do not want to run power wires and signal cables on the same side of the vehicle. This could induce car into your system. Connect the remote turn-on wire to your amplifier using an appropriate connector such as a ring terminal. NOTE : The remote wire is what sends the signal telling your amplifier to turn on or off. It is a very important wire and your amplifier will not work without it.
Click Here if you don't have a remote wire diagram are using a factory head unit. For multiple items using the remote amp you will want to use a relay. Now run your speaker wires between your amplifier and your speakers. If you need to run wires through car interior of the vehicle, make sure you run them on the same side as the RCA cables. You do not want to run power wires and speaker wires on the same side of the vehicle.
This could induce noise into your system although it is less likely than picking up noise through the RCA cables. Connect the speaker wires to your amplifier using diagram connectors such as ring terminals and to your speakers using the appropriate connectors such as female spade terminals, see photo.
Most speakers have two terminals of varying sizes. The larger terminal is the positive terminal and the smaller is the negative terminal. NOTE : If your speakers were previously connected to powered by your head unit you will need to first disconnect the speakers from the head unit. You cannot have your head unit AND your amplifier amp to the speakers. This will cause damage to hookup electronics. Now you will need to connect the negative terminal of your amplifier to the chassis ground of your vehicle.
Any metal point on diagram vehicle should work since they all lead back to the negative terminal of the battery. This negative power wire should be short and of the same diameter as the positive power wire leading to the battery. When connecting the negative power wire to ground, you may need to scrape some paint from the grounding surface.
If you have a Dremel type tool with a metal brush these work great wear eye protection. This will ensure better contact between the negative power wire terminal and the vehicle ground. This is especially important when you are diagram the area of your vehicle's gas tank.
A wrong move here could puncture the tank, cause a spark and set your vehicle on fire with you in it! If you are unsure then consult a professional.
After all connections are in place and all wires are secured, you may insert the main power wire fuse. If you are installing a car audio capacitor you will need to charge it first. This can also be done at the fuse holder. Reconnect the negative battery terminal. You just installed a car audio amplifier. Now you'll want to set your gains properly. See the instructions below. Start by turning all of the input level adjustment knobs gain controls on your components fully counter-clockwise to their minimum setting.
If you have more than one RCA pair you will want to set each gain adjustment separately.
