Frequently Asked Questions (FAQ)
- • Why does the bass feel lacking or "thin" after installing this enclosure?
Since this is a small, sealed box, it relies heavily on proper tuning. Ensure your amplifier's subsonic filter is turned off, the low-pass filter is set around 80Hz, and verify your amp can properly handle the enclosure's 2-ohm impedance load.
- • What is the best amplifier pairing to get full performance without blowing the sub?
A mono amplifier supplying 300W to 500W RMS at 2 ohms is ideal, such as the JL Audio JD500/1 or RD500/1. Keep your gain moderately tuned to respect the subwoofer's 400W RMS maximum ceiling.
- • Will this wedge enclosure fit underneath the back seat of my crew cab truck?
Likely no. The "TG" denotes a Truck Wedge shape meant to stand vertically behind the seat of a regular cab truck. For tight under-seat applications, the flatter and wider CS110LG-TW3 model is recommended instead.
- • My sub is making a scratching noise when it hits low notes. Is the voice coil blown?
Gently press down evenly on the cone. If you feel a rough, scraping texture, the voice coil is likely warped or burned from amplifier clipping. If it moves smoothly, ensure the mesh grille isn't vibrating against the surround.
- • Can I remove the TW3 driver from this box and run it in a ported enclosure instead?
Yes, the 10TW3-D4 driver works well in small ported enclosures. However, because this specific pre-built box is strictly CNC-machined and engineered for sealed air space volume, you cannot easily modify the physical box itself to be ported.
- • Why is my amp cutting out or going into protect mode when playing this sub at high volumes?
This enclosure is wired to a 2-ohm load. If you are bridging a 2-channel amplifier or using an older amp that is only stable down to 4 ohms when bridged, the excessive current draw will trip protection mode. Ensure your amp is stable at 2 ohms mono.
- • The bass sounds great on rock music but feels empty on ultra-low rap or EDM tracks. Is the box too small?
Compact, sealed enclosures prioritize tight, punchy mid-bass precision over booming infrasonic rumble. If your target frequencies are consistently below 35Hz, you will need a larger, ported enclosure layout to get that extreme low-end extension.
- • The push terminals on the side of the box are loose and causing the audio to cut out. How can I fix this?
Heavy vibrations can loosen the terminal hardware over time. Unscrew the subwoofer driver to look inside, verify that the internal spade connectors are firmly attached to the terminals, and tighten the hardware securing the external posts.

In my single cab truck with JL JD500/1 amp , this sub straight up thumps and it’s only a 10”

I have it paired with a JD500/1 and its delivering tight and clean lows. I love how it is much better than the Kicker sub I got before this one. Installing it in my Ranger was very easy too.
