Why Choose JL Audio SB-H-RIDGLNE/10W3v3/TN Stealthbox System?
Generates Clean, Powerful Bass Response
It is clear that Honda did not follow a conventional pick-up truck template when they designed the Ridgeline. From its unit-body construction to its lockable bed storage compartment, the Ridgeline sets itself apart from the herd.
The versatile and comfortable interior design does not leave much room for a big subwoofer system, so JL Audio's Stealthbox® team focused on engineering a compact solution that installs beneath the rear seat and uses slot-loading to generate clean, powerful bass response.
Contains One 10W3v3-2 Subwoofer in a Sealed Enclosure
Combined with their component speakers, this Stealthbox® can make every journey a great sounding one, without messing with your truck's utility and functionality. The Hard Data: Contains one 10W3v3-2 subwoofer in a sealed enclosure. 500 watt power handling. Wired for 2 ohm mono. Mounts under passenger side rear seat.
Frequently Asked Questions (FAQ)
- • What factory truck interior trim color does the \"TN\" suffix match?
The \"TN\" designator indicates a Beige / Tan factory carpet wrap. It is custom-dyed to blend seamlessly with first-generation Honda Ridgelines equipped with a Tan or sand-toned interior package.
- • Which model years of the Honda Ridgeline will this specific box fit?
This fiberglass enclosure is strictly engineered to follow the rear floor geometries of first-generation 2006–2014 Honda Ridgeline models. It will not fit second-generation (2017-Up) trucks.
- • Where exactly does this Stealthbox mount within the Ridgeline's cabin layout?
The housing is contour-molded to drop securely underneath the rear passenger-side bench seat, making use of the open air cavity while keeping it fully hidden.
- • Will installing this under-seat box prevent the rear seats from folding up for cargo?
No. The ultra-compact, sloped fiberglass layout utilizes "slot-loading" tech so the rear seats can still flip up, fold down, or lock flawlessly into place without hitting the enclosure.
- • What final wiring load impedance does this single 10-inch subwoofer present?
The enclosure features a single high-excursion 10W3v3-2 driver pre-wired directly to the external terminal posts to deliver a final stable 2-ohm mono load.
- • How much continuous RMS amplifier power does this subwoofer system require?
The pre-loaded 10W3v3 sub handles 500 watts continuous RMS. To maximize dynamic headroom, match it with a monoblock car amplifier pushing 300W to 500W RMS at 2 ohms.
- • Is a protective grille included, or do I need to worry about the seat damaging the cone?
The enclosure features an enclosed, down-firing structural orientation that physically anchors the sub facing down toward the floor, shielding the cone surface from passenger or seat contact.
- • Why does the low-end bass signal drop off heavily when I crank the volume up?
The stock Honda head unit uses aggressive internal equalization curves that automatically clip or filter out low frequencies at higher volumes to protect factory speakers. An active line-output converter or DSP is required to feed a flat signal.
