Step 4: Disconnect Your Speaker’s Wires

All you need to do is disconnect the power source of your car, then switch it off. After that, you must physically remove your wires from the terminals or ports.

Step 5: Determinate Relevant Connections

Once you have established all output ports, you will need to define all connections that could be crucial to the connection process.

You need to connect an output port on your sub box and an LFE jack on your receiver. All you need to do is create a connection between the jack and the port utilizing the offered hole.

Step 6: Run Your Wires

First, you need to connect the battery. Let’s start by looking for a gap or hole in the firewall of your car.

Then run your wire through this hole/gap so that your wire can reach the car’s battery. You need to get rid of the insulation at the wire’s end, where you put your car’s battery.

Afterward, create a connection between an in-line fuse and your terminal. Then, run your remaining wire underneath your car’s carpeting. Next, you have to get the wire to your car’s car trunk.

Step 7: Strengthen Your Connections

Now, it is time to reinforce your connections. 

First, you will need to connect the positive wire from your sub to a left speaker with the (+) icon. 

Next, attach negative cables to the other speaker with the (-) icon.
