What Are the Tips for Installing a Subwoofer in the Trunk?
2 Answers
Connect the red and blue wires to the input terminals of the subwoofer, then route the wires from the trunk to the dashboard, connecting them to the subwoofer output terminals of the audio amplifier or head unit. Below is relevant information: Positive Terminal: Connect to the positive terminal of the battery and ensure a fuse is installed. If the wire is not long enough, use an extension wire. Control Wire - REM (the thinner blue wire) should be connected to the head unit's control wire or the ACC terminal to control the subwoofer's power switch. Ground Wire - GND (the shorter black wire) should be connected to a nearby chassis screw. Audio Cable: Connect to the left and right channel audio output jacks of the head unit. If there is no audio output jack, install a high-to-low converter.
Every time I install a subwoofer, I first consider the trunk space. Choosing a subwoofer of the right size—not too large—ensures there's still room for luggage. Then, wiring is crucial—using dedicated cables from the battery to the trunk, ensuring a good ground connection to prevent electrical interference or short circuits. When securing it, I use bolts or strong straps to fix it to the car body, preventing noise from movement while driving. Testing the sound is important; positioning it too close to the rear panel can make the sound muffled. I also like adding some acoustic material around to absorb sound, making the bass fuller and clearer. Remember, regularly check for wire wear—safety first!
