Why Choose JL Audio SB-T-TUNDCMAX/13TW5v2 Stealthbox System?
Redesigned motor features an annular vent
Toyota's largest truck offers amazing people space, but doesn't leave much for a traditional subwoofer enclosure. It's a good thing we don't let conventional thinking get in the way of creating Stealthbox® solutions. Using the remarkable 13TW5v2 thin-line subwoofer, we have created a powerful Stealthbox® that can be installed behind the back seat of the big Tundra. One is enough for creating outstanding sub-bass with deep extension and solid impact, but for those looking for maximum performance, installing a pair of them will deliver up to 6dB more output.
Massive Shallow-Mount Lows
Armed with a massive 13.5-inch thin-line driver, this system boasts patented concentric tube architecture and a unique design that thrives in incredibly small airspace requirements. Don't let its shallow profile fool you; it delivers a crushing 600 watts RMS power handling wired to a stable 4-ohm load, diving down into a bone-rattling 20–200 Hz frequency response. JL Audio pulled out all the stops by packing in a colossal 7-inch diameter voice coil, a mica-filled polypropylene cone, a rugged Santoprene surround, and a cast alloy basket.
Frequently Asked Questions (FAQ)
- • Will the JL Audio SB-T-TUNDCMAX/13TW5v2 fit every Toyota Tundra CrewMax?
No. This Stealthbox is designed for specific Toyota Tundra CrewMax model years. Always verify your truck's year and factory configuration before purchasing.
- • Why is my 13TW5v2 producing very little bass after installation?
Incorrect amplifier tuning, reversed polarity, or improper wiring are the most common causes. Check your gain, crossover, and speaker connections first.
- • What amplifier is recommended for the SB-T-TUNDCMAX/13TW5v2?
A quality amplifier delivering around 600 watts RMS at the correct impedance is recommended. Proper gain adjustment ensures the best performance.
- • Why does the subwoofer distort when I turn the volume up?
Distortion is usually caused by amplifier clipping or excessive bass boost. Reducing the gain and tuning the amplifier correctly typically solves the issue.
- • Can I replace the 13TW5v2 with another JL Audio subwoofer?
No. The enclosure is engineered specifically for the included 13TW5v2 driver. Installing another model may result in poor fitment and reduced performance.
- • Why do I hear rattling behind the rear seats when the bass plays?
Loose trim panels, seat hardware, or stored tools are the most common sources of vibration. Securing these items usually eliminates the rattling.
- • Does installing this Stealthbox affect the rear seats?
No. The enclosure is designed to fit behind the rear seats while maintaining normal seating functionality and comfort.
- • Does the 13TW5v2 need a break-in period?
Yes. Most users notice smoother, deeper bass after several hours of normal listening as the suspension naturally loosens.
