Why Choose JL Audio CS112TG-TW3 Enclosed Car Subwoofer?
Amazing Sub-bass
Enclosed Subwoofer System with Single 12TW3-D4 Subwoofer Driver, Black Carpet (400 W, 2 Ω) - Sealed Enclosure In this sealed Truck PowerWedge™ subwoofer system, we harness the performance of the 12TW3 to deliver amazing sub-bass from an enclosure that is only 6.25 in. (159 mm) deep at its base and 4.1 in. (104 mm) at the top.
Carefully Engineered
This enclosure design has been carefully engineered to the optimum sealed enclosure alignment for the 12TW3 and has been fine-tuned through extensive real-world listening. This subwoofer system is shipped wired, loaded and ready to connect via a five-way binding post terminal.
Finish: Black, high-grade automotive carpet with "JL AUDIO" embroidered in silver on the front baffle. A steel mesh grille is included to protect the subwoofer driver.
Frequently Asked Questions (FAQ)
- • Why does my amplifier keep overheating or clipping when running this subwoofer?
This enclosure is pre-wired internally to a 2-ohm total load. Your amplifier is likely not stable at 2 ohms, or you haven't set the gain properly, forcing the amp to work past its thermal limits.
- • Why does the bass suddenly cut out or sound extremely weak when I turn up the volume?
This usually happens if you are underpowering the sub with a weak amplifier or if the amplifier’s protection mode triggers because it cannot safely deliver 400 watts RMS into a 2-ohm load.
- • Can I rewire the terminal cup on the outside of the box to change it from 2 ohms to 4 or 8 ohms?
No. The driver inside is a dual 4-ohm voice coil sub pre-wired in parallel. You can only change the impedance by physically removing the woofer from the box and rewiring it to an 8-ohm series configuration.
- • Why does the sub fail to play the deepest, ultra-low frequencies well in my truck cabin?
This is a limitation of shallow-mount, sealed wedge boxes. While they offer incredibly tight, punchy bass for rock and electronic music, they naturally roll off on sub-bass frequencies below 30Hz.
- • I hear a prominent rattling or air-hissing noise coming directly from the front panel. Is the sub blown?
Not necessarily. The high-excursion TW3 cone can strike the integrated metal mesh grille if the physical grill becomes loose or slightly bent inward during installation. Inspect the clearance first.
- • What happens if I connect an amplifier that pushes 600W-800W RMS to this PowerWedge system?
Doing so risks burning out the voice coils or ripping the suspension. The TW3 thin-line driver is strictly rated for 400 watts continuous RMS; pairing it with excessive power will cause mechanical failure.
- • Why does the bass sound completely out of phase and hollow after hooking it up to my factory stereo?
This is a common wiring issue during tap-ins. If the positive and negative speaker source wires going into your Line Output Converter (LOC) or amp are reversed, the sub will play out of phase with your factory door speakers.
- • The bass sounds great outside the vehicle, but inside the cabin it feels completely dead. How do I fix this?
You are experiencing destructive wave cancellation. Try physically rotating the wedge enclosure to face a different direction (such as firing toward the back wall vs. the floor), or flip the 0/180-degree phase switch on your amplifier.
