The Basics of Installing an Aftermarket Amp for a Nissan 350z

Getting the full optimal audio experience from a car audio system is often the impetus for aftermarket upgrades. For the Nissan 350z in particular, when the time comes to enhance the existing sound system, installing an aftermarket amp can be the most rewarding of upgrades. Installing this amp requires knowledge of the 350z's audio wiring diagram, and the information provided in this article will help explain exactly what it entails, as well as provide examples and tips along the way.

Understanding the Wiring Diagram for the Nissan 350z

Before beginning the installation process for a new amp in a 350z, it is important to have a clear-cut understanding of the wiring diagram for the audio system. Though there is a bit of a learning curve, the wiring harness diagram of the 350z is fairly straight-forward. It is important to become familiar with the system’s components - the head unit, power wires, speakers, and preamp outputs - so as to understand where the new amp needs to be connected to.

Audio Connections Necessary for Installation

In order to connect the new amp into the existing audio system, there are certain connections that must be made between the car audio components. Generally, in order to install an aftermarket amp, a separate wire must be run from the power cable, as well as one from the chassis ground in the engine compartment. In addition, an isolation device, such as a capacitor, should also be used in order to protect the car's main power supply.

Installing the Speaker Wires

When wiring the speaker wires for the amp, it is important to use a high quality set of speaker cables and to take extra care when inserting them into the vehicle. Start by finding the speaker wires from the head unit in the dashboard, and then connect these to the outputs on the amplifier for each channel. Once the speaker cables are properly disconnected from the head unit and connected to the amplifier, you can begin the mounting process.

Mounting and Sealing the Amplifier

Mounting the new amp will help ensure it is securely held in place and protected from any potential damage. Before tightening the screws, it is important to make sure the amp is level - this can be accomplished with a carpenter's level or a similar tool. When finished, the area around the amp should be thoroughly sealed with silicone caulk or spray foam to ensure water does not leak in.

Final Testing and Troubleshooting

Once all the necessary connections have been made and the amp has been successfully mounted, final testing should be done to make sure everything works as desired. Have a helper turn the key to the run position in order to check if the amplifier is on and functioning correctly. If any issues arise during this testing phase, it would be wise to consult a professional before attempting any further troubleshooting yourself.

In conclusion, though the process of upgrading a Nissan 350z audio system with an aftermarket amp may seem daunting at first, understanding the wiring diagram, making the correct connections, mounting, and testing the amp will ensure enjoyable listening experiences.
