Simply swap your factory underseat woofers with our plug & play upgrade kit and, get incredibly powerful, tight bass.
MORE BASS WITHOUT CLARITY IS JUST NOISE.
Our woofers are not only louder, they're cleaner and clearer.
NEARLY FLAT FREQUENCY RESPONSE FOR EXCEPTIONAL LINEARITY
in the key sub / mid-bass frequency range from 40Hz to 200Hz (+ or - 3 dB). Which means "clean" and balanced bass.
SUPER TIGHT, PUNCHY MIDBASS
Your factory underseat woofers aren't just subwoofers; they're midbass drivers. That means they play not just the lowest frequencies, but also "punchy" midbass frequencies like snare drums and high bass guitar notes.
Unlike our woofers, which are designed to outperform the factory woofers for both subwoofer and midbass frequencies, other underseat subwoofer upgrades on the market are only capable of playing sub frequencies, not midbass, so you miss a huge portion of the frequency range.
HOW DO WE DELIVER BASS THAT'S LOUDER, CLEANER, AND TIGHTER WITHOUT CHANGING THE FACTORY AMP?
In a word, efficiency. Every watt of power generated by your amplifier yields about 2x the bass output with our woofers vs factory woofers.
If you're not familiar with the concept of "efficiency" in audio, just use this analogy: with your factory woofers, your amplifier is like a 200hp motor in a 4,000lb Camry. With ours, it’s like the same 200hp motor in a 2,000lb Lotus Elise - twice the performance with the same power.
2X THE OUTPUT
Our woofers are 10 dB+ louder from 20Hz to 60Hz vs factory woofers, resulting in twice the loudness in this critical “sub-bass” range (and over 8x the sonic energy). You won’t just hear the bass; you’ll feel it.
100% PLUG & PLAY
Installs and fits just like your factory Rolls Royce woofers, right down to the bolts and factory-style plug.
SIMPLE, DO-IT-YOURSELF INSTALLATION
Takes less than 90 minutes and only basic tools, even for a total novice. No complex wiring or additional hardware or installation is required. Simply unbolt your front seats, remove the woofer covers, unbolt your factory woofers, and install ours. That's it!
