Stealthbox® for 2019-Up (Gen 4) Chevrolet Silverado / GMC Sierra 1500 Crew Cab Trucks and 2020-Up 2500 / 3500 Crew Cab Trucks

This generation of Chevrolet/GMC trucks is bringing new levels of interior refinement and technology to the full-size truck segment. Our Stealthbox® enhances all this by adding impressive, high-quality bass without losing any of your precious people space or interior functionality.

The Stealthbox® slips under the truck's rear seat and features two of our revolutionary 12TW3 thin-line subwoofers, giving you absolutely stellar sub-bass impact and quality. We even left a perfect spot in the middle of the enclosure for a clean, hidden amplifier installation!

The Hard Data: Contains two 12TW3-D8 subwoofers in a down-firing sealed enclosure. 800 watt power handling. Wired for a 2 ohm load. Installs under rear seat. Will not affect the folding of the rear seat or rear leg room.

Work flawlessly on 2011 Golf MK6 2.5L

Bought these to replace worn out OEM speakers that would rattle every time I closed the door or drove with the windows partially open. Turns out you can only slam the door shut so many times over the life of a VW before the speakers deteriorate.

They sound better than OEM, I'm not enough of an expert on audio quality to rate them beyond that. I have DSP on a aftermarket Xtrons headunit ( IA92MTVL-US ), no amp.

The fit is identical and connectors work flawlessly, only struggle I had was drilling out the old rivets and making sure I still had a metal ring left in the plastic afterwards to hold the new rivets (you will need a rivet tool to install these new woofers, the box does come with 10 rivets). The old rivets loved to spin in place after drilling them and pretty much melted the plastic on the old speakers. Wiring was straight forward, make sure you connect ground cable with black line to the one on the adapters for the tweeters, other than that they just get taped onto the plastic housing unlike the woofers that are riveted.

The manual that comes with the product is useless, and the online version of it equally as useless, but trust me you will figure it out, or at least I did, I decided to put the X shaped tape on the back of the tweeters as well as putting some glue between them and the casing to be sure. The YouTube video from Focal was dated and didn't help much except point out the obvious.

Punchy

Great value for 2 10s in a well put together box!

Solid starter set

The amp rack itself mounts great. Powers the subs as they should, assembly was easy!

Perfect fit fast shipping.

Rack came in within 2 or 3 days of ordering. Fit perfect.

The perfect bass upgrade!

I was hesitant at first because I didn’t think a subwoofer upgrade would be too noticeable in my 2023 Raptor with the B&O system and would potentially muddy the sound but I was wrong. You don’t realize how underwhelming the factory system is until you get the SGS stealth kit. The subs hit hard and are extremely precise versus the overly bassy factory woofer.

Fit was amazing and the performance is exactly what I needed for the type of music I listen too.

Made the install painless. Worth every penny.

👌🏽👌🏽

The perfect adapters for installing some beefy 6.5s in a Ford. Add some heated threaded inserts and you have yourself the perfect adapter.

Fit great

Drill 1/8” holes and the screw right on. Fit was perfect. I also added sound mat and my doors have solid “thud” when you tap them and the speakers sound like they are connected to an actual stereo, not some transistor radio.

They shorted my two screws but I had similar ones on hand so no biggie. Overall, quality product, easy install and significant improvement in sound.

Very well made and perfect size

Outstanding Soundproofing with Blackhole MAT

I recently purchased the Blackhole MAT Self-Adhesive Three-Layer Damping Material (4.5mm thick, 20” x 79” sheet) to install in my 2023 Ford Bronco Raptor, and I couldn’t be happier with the results.

The material was straightforward to install, and having a good Sound Deadening Installation Roller made a huge difference. The roller helped ensure the material adhered smoothly and securely, maximizing its effectiveness and saving me time during the process.

Once applied, the results were immediate and impressive. The Blackhole MAT significantly softened interior sounds, reduced road noise, and created a quieter, more refined cabin. This improvement has taken my music-listening experience to the next level, allowing me to fully enjoy the quality of my upgraded audio system.

The Blackhole MAT is a high-quality product that delivers on its promise of excellent sound insulation. If you’re considering upgrading your vehicle’s acoustic environment, I highly recommend this material—and don’t forget to invest in a good roller for the best results!
