The battery of the car is disconnected till the installation is done. The negative terminal cable is removed from the terminal. A screwdriver or an appropriate wrench can be used to loosen it. A ring terminal is attached between the power cable and positive terminal of the battery. The cable for power supply is routed between the compartment where engine is kept and the vehicle’s inner cabin. There is generally an aperture for the wire but if there is no such facility a hole can be drilled and use a grommet for protection.
The stereo is then removed out of the dash. This is different for each vehicle and can be done using a manual of the car. After the stereo is removed, the wiring of the stereo is disconnected. The wiring can be either single or many attached together. The stereo is then connected to the harness adapter from the vehicle. The harness has markings that show how the connections have to be made.
Then, the cable for the signal and the lead for turn on are connected to the harness adapter. The lead for turn on is present in any wiring kit. These two cables are then touted to the vehicle’s floor through the rear part of the stereo. The carpets can be lifted using some tools for removing it. The cables can then be passed through the floor carpeting to the battery. It is advisable to do in opposite directions in order to minimise the interference.
The subwoofer is then placed in the vehicle’s trunk. The sub is then grounded by connecting the corresponding wire to some bolt of the car. This can be done by lifting a part of the carpet for a bolt. The cable for signal, power supply and the lead for turn on are connected.
The stereo is then replaced back in the dashboard of the car. Then the battery is reconnected by placing back the negative terminal cable on the negative terminal. The clamp can be tightened with the help of a screwdriver or a wrench.
The above were some guidelines on how to install a subwoofer in a factory stereo. The quality of the audio can be improvised by adding a powered or non powered sub. The above was a discussion of connecting a powered sub. A non powered one can be connected only if the stereo has an amplifier built in the stereo.
