All About Tru Technologies
TRU Technology builds high-end car audio amplifiers and line amps for sound-quality fans. The brand comes from the competition scene. The goal is simple: clean power, wide bandwidth, and a silent noise floor.
Heritage and build
TRU makes products in small batches in California. Skilled builders assemble and test each unit. This control improves consistency and long-term reliability.
Product families
- Billet v2: Class-A/AB reference amplifiers for front stage duty. They focus on low distortion, linear gain, and detail at low listening levels.
- Tungsten & Tungsten Grande: Class-AB power with SQ voicing. These models suit active two-way and three-way systems where headroom and tone matter.
- Line Amps (LINE-2CA, LINE-6 v2, LINE-8 v2): Front-end signal amps that lower noise, stabilize gain, and improve dynamic range before the main amps.
Why competitors use TRU
TRU gear stays quiet between notes. It holds frequency response flat across the band. It keeps output stable during long listening sessions. Installers trust it for judging lanes because results are repeatable.
System use cases
Use Billet v2 for tweeters and midrange where micro-detail matters. Use Tungsten or Tungsten Grande for midbass or full-range channels that need strong current. Add a TRU line amp when your DSP or source needs cleaner gain structure.
Buying and support
TRU protects customers with an authorized-dealer process. Some models require a phone or email consultation before purchase. If you choose an authorized install, the brand may offer extended warranty coverage per its terms. Audio Intensity provides free, insured shipping in the continental USA, order confirmation, and tracking. Our team can assist with gain staging, wiring, and heat management so your system performs as designed.
