The amp will lead a dull and empty life.
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.
Have you checked for a lose ground power or rem wire?
NO. Just ground the amp to the chassis try to make ground short as possable about 12 inches is plenty. BE SURE GROUND WIRE IS THE SAME GAGE AS THE POWER WIRE. If its an 8 ga. + then use 8 ga. for the ground.
Wire the subwoofer to and AMP and the amp has to be directly hooked up to your battery. There is a second wire that is hooked up to a wire that only has power when the keys are turned. This turns the Amp on by turning on a relay in the amp powering the sub. And connect the ground to something steel in the car.
Typically a poor ground, or some how the red wire is touching the black
By removing the ground wire from the battery and putting an amp meter in series between the battery and wire and measure the amp draw after sometimes 15 minutes.
RED wire goes on +, and the black wire gets wired to the body of the car. Which is ground -
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.
remote wire is to control amp, bass coming from subs, and the frequency
the ground wire runs to the chassis (almost anything metal on the car) so if your amp is in the rear you could run the wire to the spare hull and connect wire via a wire terminal you can buy at any car audio place usually about $5 to $15 bucks depending upon size and type of metal brass,gold plated ect. the ground wire runs to the chassis (almost anything metal on the car) so if your amp is in the rear you could run the wire to the spare hull and connect wire via a wire terminal you can buy at any car audio place usually about $5 to $15 bucks depending upon size and type of metal brass,gold plated ect.
Yes a remote wire is necessary. You must wire the remote wire from the amp to and ignition source of power (a component which turns on when the ignition in the car is engaged.) i.e. the radio. The remote wire signals for the amp to power on.
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.
