An ammeter must be connected in parallel to the circuit. If you do not understand the difference between parallel and series connection then you should leave it to a competent mechanic/electrician.
Measures the amperage of the current .Your battery is in series with your car amp meter .
the capacitor has 2 wires or poles, one is the ground or negative and the other one is the hot or positive... if it is for car audio amp the ground is connected to the chassis and the positive is connected to the battery and to the positive wire of the amp.
buy a wire kit with thick enough wires for the amp.. It should have the instructions but heres the basics.. thick wire goes to battery from amp and you need to drill a hole through firewall (usually under carpet buy you gas and break pedals) to run it and it should have a inline fuse.. RCA wires go from amp back of radio a wire from amp ground need to be connected to a large metal part of your car. memory wire needs to hook to a power source that's only on when your cars on that way your amp does not kill your car battery when you park. and then connect all the speakers.
It will be a 12 volt battery.
In 24 hours it will be charged enough to start the car. You really need a much larger charger for a car battery.
When charging a car battery, the choice between 2 amp and 6 amp depends on the battery's condition and the charging speed you desire. A 2 amp charger is better for maintaining battery health and is suitable for trickle charging or when you have more time, while a 6 amp charger will charge the battery faster but may generate more heat and could be less gentle on the battery. For optimal results, refer to the battery manufacturer's recommendations.
Voltage is the same but amp hour capacity of the car battery is much higher.
I will answer your question with another question: how did you get into my car?
Around 330 watts. For a car battery.
Depends on the battery you buy. They come in different CCA.
Positive post of capacitor is connected to the heavy amp cable. The ground terminal (or case) of the capacitor is connected to the car's ground or a ground wire that leads to the car's chassis. That's it.
To install an amp in an Almera, you will need to connect the amp's power wire to the car's battery, ground the amp to a metal part of the car's chassis, and connect the amp's remote wire to a source that turns on when the car is started. You will also need to run RCA cables from the head unit to the amp for signal input, as well as speaker wires to connect the amp to the car speakers. It's recommended to consult a professional for the installation to ensure safety and proper functionality.
