For instance if we need to know power but we only have amperage (I) and resistance (R) then we could substitute I*R in the power equation (because according to Ohm's law E=I*R) and get P = I*R*I. Parts needed Amplifier Power Kit For installing an amp, you will need this kit because it contains the wiring that you need to run power wires from the amplifier to the battery. There is no other way that you can really know how the speakers will sound to you.

Use the factory speaker screws to secure the mounting bracket to the factory speaker opening. As it moves back to the rest position it then travels the final 90 degrees to the 360 degree mark. Simply and quickly explained Ohm's law is:E=I*R This is best explained in that the E represent voltage measured in volts, I is current measure in amps and R is the resistance that is measured in ohms. 55 cubic foot box for our sealed enclosure.
I have decided to list the steps in point form so that they will be easier to follow. Below are the basic steps that are involved in installing an amplifier in your vehicle. Some vehicles will require additional steps, but this will at least give you a good starting point.
Power wire connection/routing:
The power wire for the amplifier needs to be routed from the car battery under the hood to the amplifier and the steps for doing this are below.
1. Open the hood and find the battery. Disconnect the positive terminal from the battery.
2. Check to see how the amplifier power wire ring terminal will connect to the battery.
3. Crimp a ring terminal onto one end of the power wire. Cut the power wire approximately 6-8" long. Then you have to attach one end of the fuse holder to the other end of the ring terminal. Attach the other end of the fuse holder to the remaining portion of the power wire. DO NOT CONNECT THE RING TERMINAL TO THE BATTERY OR CONNECT THE FUSEHOLDER AND INSERT THE FUSE UNTIL YOU ARE READY TO TURN THE AMPLIFIER ON.
4. Decide upon a point in the firewall to run the power wire through to the inside of the vehicle. If its at all possible, run it through an existing grommet on the firewall. Usually there are more access points on the driver's side anyway. If there are no acceptable holes, drill one in yourself.
Install a grommet into the hole before pushing the power wire through to prevent damaging the wire. Before you run the wires through, you will have to double-check that you can reach the area of the firewall where the wires will enter the inside of the car. IF YOU HAVE TO DRILL A NEW HOLE IN THE FIREWALL, BE SURE THAT THERE ARE NO EXISTING WIRES BEHIND THE AREA WHERE YOU WILL BE DRILLING.
5. Under the hood, have to run the power wire from the battery to the grommet on the firewall. Just make sure that it is not in the way of moving parts on the engine, hood hinges or heat sources as the heat will cause obvious problems.
6. You must route and secure the power wire from the battery to the firewall. Use wire ties to help you to attach the power wire to other cables or fixed points under the hood.
7. Feed the power wire through the firewall. Be sure to avoid using sharp objects to push it through. You may need to use a knife or blade to cut the grommet so the wire will go through though.
8. Pull the power wire through the firewall from the inside of the vehicle until the extra wire is out from under the hood. Keep some slack in the cable inside the engine compartment so it won't rub or be tugged on.
9. Route the power wire from the inside of the firewall to the location of the amplifier. Typically the power wire will go behind the kick panels, under the doorsill, and into the trunk.
10. Now you have to apply caulk to the opening in the firewall where the power wire is going to be inserted so water will not leak into the vehicle's interior.
That is all it takes in order to get your amplifier installed. Now it is on to taking out your old radio.
