Frequently Asked Questions (FAQ)
- • Why does my square subwoofer sound weak after installation?
Weak bass is usually caused by an enclosure that doesn't meet the recommended specifications or incorrect amplifier tuning. Check the box volume, crossover settings, and speaker polarity to improve performance.
- • Can I use this in a sealed enclosure instead of a ported box?
Yes. It performs well in both sealed and ported enclosures when they are built according to the recommended internal dimensions.
- • Why does my amplifier keep going into protection mode?
This often happens because of an impedance mismatch, wiring fault, or insufficient power supply. Verify all wiring connections and confirm that the amplifier supports the final speaker load.
- • Can I connect this to a factory car stereo?
Yes. You'll need an external amplifier, and many factory audio systems also require a line output converter for proper signal integration.
- • Why does the bass become distorted when I turn up the volume?
Distortion is commonly caused by amplifier clipping or gain settings that are too high. Properly adjusting the amplifier and crossover will produce cleaner bass and reduce the risk of damage.
- • Does it need a break-in period before it reaches full performance?
Yes. Playing music at moderate listening levels for several hours allows the suspension to loosen naturally and improves bass response.
- • Why do I hear rattling from my trunk during heavy bass?
Loose trim panels, license plates, or enclosure hardware are often responsible for unwanted vibrations. Tightening loose components and adding sound-deadening material can significantly reduce rattling.
- • Can I use an amplifier that produces more RMS power than the subwoofer is rated for?
Yes. A properly tuned amplifier with clean output is generally safer than an underpowered amplifier that clips when pushed too hard.
- • Why does the cone move but produce very little bass?
This usually indicates incorrect crossover settings, reversed polarity, or an air leak in the enclosure. Inspect the wiring and enclosure before assuming the subwoofer is defective.
- • Can I wire two subwoofers to the same mono amplifier?
Yes. Calculate the final impedance carefully and make sure it matches the amplifier's supported operating range before connecting both subwoofers.

Real strong and loud, but maybe a bit big for my hatchback. If you got a truck, this would be the perfect sub for you.
