FAQs
What is the internal volume of this enclosure?
The QPower HD115-VENT-SQ has an internal volume of 2.7 cubic feet.
What size subwoofer does this enclosure fit?
This enclosure is designed to fit a 15-inch subwoofer.
Can I use this enclosure with any 15" subwoofer?
It is designed for 15" subwoofers with a square mounting profile. Crucially, always check your specific subwoofer's recommended enclosure volume (2.7 cu. ft. is a common requirement for vented boxes) and mounting dimensions.
What material is the enclosure made from?
The enclosure is constructed from 1-inch thick Medium Density Fiberboard (MDF).
Does this enclosure come pre-wired?
The enclosure features a terminal cup with gold post connectors for easy wiring to your amplifier, but the internal wiring to the subwoofer and the speaker wire from the amplifier to the terminal cup are not pre-installed; they need to be connected by the user.
What is the benefit of a vented enclosure?
A vented (or ported) enclosure is designed to increase the efficiency and output of the subwoofer, particularly at lower frequencies, resulting in deeper and more powerful bass compared to a sealed enclosure of similar size.
How should I clean the enclosure?
You can clean the charcoal carpet covering with a soft, dry cloth. For minor stains, use a slightly damp cloth with mild soap and dry it immediately. Avoid using abrasive cleaners or excessive moisture.
Troubleshooting
No sound or distorted sound from subwoofer.
Check all wiring connections to the subwoofer, terminal cup, and amplifier for looseness or incorrect polarity. Ensure the amplifier is properly powered and sending a signal. Verify the subwoofer's impedance is compatible with the amplifier.
Rattling or buzzing noises.
Ensure the subwoofer is securely mounted to the enclosure and that the enclosure itself is firmly placed in the vehicle. Check for any loose items inside the enclosure or on the vehicle's interior that might be vibrating.
Weak bass output.
Confirm the enclosure volume is appropriate for your subwoofer model. Check for air leaks around the subwoofer mounting or enclosure seams. Ensure the subwoofer is wired in phase with other speakers in the system.
Enclosure material seems damaged.
Inspect for any signs of physical damage during shipping or installation. If significant damage is present, contact the retailer for potential replacement options.

Setup, Compatibility & Care
Setup:
- Subwoofer Mounting: Ensure your 15" subwoofer has a square mounting pattern and fits the cutout dimensions. Secure the subwoofer firmly to the enclosure using appropriate screws.
- Wiring: Connect your subwoofer to the terminal cup connectors using speaker wire. Ensure correct polarity (+/-) is maintained to avoid phase issues.
- Amplifier Connection: Connect the enclosure's terminal cup to your car amplifier using high-quality speaker wire. Observe the impedance (ohms) rating of your subwoofer and ensure it is compatible with your amplifier's output capabilities.
- Placement: Install the enclosure securely in your vehicle, typically in the trunk or cargo area, ensuring it does not obstruct safety features or driving visibility.
Compatibility:
- Subwoofer Size: Designed for 15" subwoofers.
- Subwoofer Shape: Requires a subwoofer with a square mounting profile.
- Volume: Ideal for subwoofers specifying a 2.7 cu. ft. sealed or ported enclosure. Always consult your subwoofer's manual for recommended enclosure volume.
- Amplification: Ensure your amplifier has sufficient power (RMS wattage) to drive the connected subwoofer and can handle its impedance.
Care:
- Cleaning: Wipe the charcoal carpet with a soft, dry cloth. For tougher spots, use a slightly damp cloth and mild soap, then wipe dry immediately. Avoid harsh chemicals.
- Connections: Periodically check wiring connections to the terminal cup and ensure they are secure and free of corrosion.
