Is the Effect Good When Placing a Subwoofer in the Car Trunk?

[Everdeen]

Placing a subwoofer in the car trunk indeed delivers excellent results. The reasons for the good performance of the subwoofer and the installation methods are as follows: Reasons for the good effect of placing a subwoofer in the trunk: For box-type subwoofers, placing them in the trunk is highly effective. It not only provides excellent bass performance but also creates a surround sound effect. Additionally, since subwoofers are generally large in size, placing them inside the car can be somewhat inconvenient. Therefore, the trunk is undoubtedly the best choice. Installation methods for the subwoofer: Connect the positive 12V wire (red cable) to the positive terminal of the battery, and ensure to include a fuse. If the wire is not long enough, use an extension wire to lengthen it. Connect the control wire -REM (a thinner blue cable) to the main unit's control wire or the ACC terminal to control the subwoofer's power switch. Then, connect the ground wire -GND (a shorter black cable) to a screw position on the car frame near the subwoofer. Finally, connect the audio cable to the left and right channel outputs of the main unit's audio output port. If there is no audio output port, install a high-to-low converter port.

Personally, I think installing a car subwoofer in the trunk is quite powerful—it really enhances the music's impact, though the effect isn't always perfect. For example, in enclosed spaces, the sound can feel a bit muffled, with the bass not coming through clearly due to attenuation as it travels from the trunk to the seating area. Adding soundproofing pads can help buffer resonance. I've done this modification before—using professional anti-vibration mounts to secure it properly minimizes rattling and doesn’t take up much space, so daily storage isn’t an issue. However, installation quality matters: avoid messy wiring to prevent short circuits or fire risks. Overall, it’s great for audiophiles but might feel too loud for everyday driving. I’d recommend testing it at a modification shop first. This setup saves more space compared to installing it under the seats.

From a usage perspective, installing a subwoofer in the trunk can yield decent results, but it largely depends on the vehicle model. I've tried it in my family car—sound quality tends to be muddier in the rear of compact cars, while larger SUVs perform much better due to their spacious interiors allowing smoother sound propagation. The key is securing the subwoofer box firmly to prevent it from shaking loose and causing injury, especially during sudden braking—safety comes first. During installation, it's advisable to add some soundproofing materials to minimize body resonance noise, which can affect ride comfort. The cost isn't high, but be sure to choose the right size to avoid taking up too much space. While it enhances musical enjoyment and convenience, it's not a top-tier solution. It does enrich the audio experience, but regular inspection and maintenance are necessary.

I think the effect varies from person to person, but installing it in the trunk is acceptable, especially for parties or long-distance driving. The bass is fuller, but the sound can sometimes be muddy and requires tuning. In my personal experience, securing it properly hasn't caused major issues, but don't overlook moisture protection to avoid damage from dampness. It's suitable for music enthusiasts.

From personal modification experience, the effect of a trunk subwoofer depends on installation details. It must be securely fixed with anti-vibration brackets, and soundproof foam should be added to reduce resonance. Sound loses significant energy when traveling from the rear to the front, requiring tuning for improvement. It's recommended to choose a sealed enclosure design and match it with the head unit's frequency adjustment to avoid distortion. While space usage is manageable, wiring layout should be tidy to prevent hazards. Give it a try—you might be pleasantly surprised.
