you would usually use a rubber grommet from a parts house ....simply find a place in the fire wall ...drill the appropriate size hole for the grommet and allow a liitle play among the power wire and grommet.i usually will add a dab of super glue just so it dont come out into either side
Is because of the power rang. The power passing through 6mm2 cable cannot pass through 2.5mm2 cable.
Question: Can a power amplifier amplify the power? An amplifier can amplify the voltage or the current. Power can be converted to heat.
battery cable connection , dead battery
A voltage amplifier does not have to supply significant current bur a power amplifier does.

No. In an amplifier, Power Out > Power in. In a transformer Power Out ~= Power In (minus internal losses). An AC generator is more like an amplifier than a transformer.
No.
A power amplifier may also boost voltage; in audio equipment, power amplifiers often have a dial on the front that is used to control the input voltage gain. A simple power amplifier is composed of a single transistor; this type of configuration cannot provide voltage amplification as well. A voltage amplifier stage is needed. So the above example of an audio power amplifier is actually a voltage amplifier stage, followed by one or more power amplifier stages.
Installing a Car AmplifierCar amplifiers can greatly enhance the sound quality in a car audio system. They are used to further power the existing speakers and to power additional units such as subwoofers.Before the Installation1- The first thing to do when installing an amplifier in your vehicle is to figure out where the amplifier will be. It can be placed anywhere inside the car however the most common places are in the trunk or under the passenger's seat.2- Next you will need to purchase the correct wiring for your specific amplifier. The thickness of the power cable will vary depending on wattage required. You will also need a ground cable that is long enough to reach the amplifier, an RCA signal cable that will go from the head unit to the amplifier, a 'remote on' wire and a speaker wire.3- Gather the correct tools needed for the installation; a screwdriver, wire cutters, pliers, sandpaper, a utility knife, masking tape and 2 crimp-on o-ring ends to protect the ground and power cables.Installation1- Disconnect the ground cable from the battery.2- Connect the side with the positive power cable to the positive connector on the battery, place the ring-o on this connector and then install the fuse.3- Reach the cable to the area where the amplifier will be.4- Using a metal bolt or screw near the amplifier, connect the ground cable to it using a ring-o. Make sure to clean the metal with the sandpaper beforehand.5- Removing the head unit, connect the signal and remote on wires from the head unit to the amplifier. Then connect the RCA connectors and the remote on wire to the head unit.6- Bringing the speaker wires from the speakers to the amplifier, connect them by first stripping a quarter inch of the wire tip then connecting them to the amplifier using pliers. Make sure to connect the positive with the positive and the negative with the negative.7- Now attach the amplifier safely to the car so it will not move while driving.8- Reconnect the car battery and try it out.If the audio system does not function, make sure that the amplifier is properly grounded. This is the most common reason that it will not work.
Adding an amplifier is a great way improve the sound quality of your system. It can add enhanced detail and realism as well as volume and impact. The transformation of sound is unmistakable and will make driving much more enjoyable. Before installation, determine a good place to locate your amplifier. Good places are usually under a seat, in a trunk, or cargo area. Amplifiers have a tendency to get warm and will need a location that has enough space and ventilation. Since most amplifiers systems do not come with wires, you will need to purchase an amplifier wiring kit. Since the wires you install will be connected directly to the battery, disconnect the negative battery terminal to prevent electrical damage. Run the main power cable from the battery to the amplifier location. Connect this wire to the positive battery terminal. Be sure to remove the fuse located on the power wire before installation. Route the entire power cable through the firewall, through the door, and under the carpet to your amplifier. You may need to remove the back seat when routing the wire into the trunk. Next install the signal cables from the receiver to the amplifier. Run the signal cable on the opposite side of the power cable. Connect the amplifier turn-on lead to the stereo and install it along with the signal cable. Connect both cables to the amplifier. You will need to install a ground lead to the amplifier. This wire should be short and connect directly to a metal component of the car. This could be the chassis or frame of the vehicle. Your final connection will be from the amplifier to the speakers. Use good quality wiring for your speakers. Different quality speaker wires will have a noticeable difference in the quality of the sound. 12 gauge wire is the recommended size for cars. If you need to make longer runs in bigger vehicles then use 16 gauge wire. When all your connections are complete, you are ready to install the fuse located near the battery and reconnect the negative battery terminal. Be sure to reference your owner’s manual for the optimal settings on your amplifier. When routing wire through your car, try to find existing wire connections to pass them through
An amplifier will power your subwoofer so they can work.
You need to find out what output connections are on your soundboard and what input connections are on your amplifier. If you don't know this, a 1/4 inch cable usually will work at both ends.
