Choose the Right Subwoofer Type for Your Installation

Different vehicle setups and space constraints require different subwoofer designs. From plug-and-play powered solutions to ultra-compact shallow mount options, each type offers unique advantages for specific installations. Powered subwoofers include built-in amplification for convenient setup, while shallow mount designs fit behind seats or in tight spaces. Spare tire subwoofers maximize trunk space by replacing your spare tire, and enclosed subwoofers arrive ready to install with optimized acoustics. Select the type that best matches your vehicle's layout, installation preferences, and performance goals.

Mike Rodriguez, Houston, TX

Perfect Factory Fit in My F-150

"I was skeptical about ordering a custom box online, but this thing fits my SuperCrew like Ford designed it themselves. The bass hits clean and deep without any rattling, and I didn't lose any storage space. Installation took 20 minutes. The build quality is incredible – thick MDF, perfect carpet finish, and the wiring connections are professional grade. Worth every penny."

Chris Patterson, Los Angeles, CA

Destroyed My Old System Performance

"Upgraded from a prefab box to the Audio Intensity ported enclosure and holy cow, what a difference. The bass extension is insane – hitting frequencies I never knew my subs could produce. My friends can't believe it's the same subwoofers. The tuning is perfect and the build quality shows in every detail. Customer service helped me pick the right size for my setup."

Sam Mitchell, Tampa, FL

Competition Performance for Daily Driving

"Wanted competition-level bass for my daily driver without the crazy space requirements. The sealed Professional Series box delivers tight, accurate bass that sounds amazing with every genre. The internal damping eliminates any unwanted resonance, and it handles 1500 watts without breaking a sweat. Build quality rivals boxes costing twice as much."

Brandon Lewis, Rochester, NY

Genius Flex Design Changed Everything

"The Flex Series is brilliant engineering. Switched from dual 10s sealed to single 12 ported in under 10 minutes just by swapping plates. Sound completely transformed – went from tight bass to deep, booming lows. The modular design means I can experiment with different setups without buying new boxes. Customer service explained everything perfectly."

Amanda Stevens, Denver, CO

First Build Success Story

"Never built a car audio system before but Audio Intensity made it foolproof. Their team helped me choose the right enclosure for my subs and space. The pre-cut terminal cup and internal wiring layout made installation simple. Three months later and I'm getting compliments everywhere I go. The bass is clean, powerful, and exactly what I wanted."

Tony Martinez, Elite Car Audio, Phoenix, AZ

Professional Installer's Choice

"I've been installing car audio for 12 years and these are the best enclosures I work with. The precision is incredible – every cut is perfect, joints are rock solid, and the internal bracing eliminates any flex. My customers always comment on how professional the installations look. Audio Intensity saves me time and delivers results that keep clients coming back."
