Refining the sound is a process on its own. Objective adjustments take you only so far. The ultimate test is our ears and the final sound is only achieved through extensive listening sessions amongst company peers. What you’re hearing is OEM Audio Plus.

Engineered to perform together.

By optimizing our sound solutions as "Systems" as opposed to "parts" we are able to take sound reproduction within this space to a level that hasn't been done before - all the while performing real-time diagnosis via our Digital Signal Processor. This level of scrutiny and control results in a powerful experience without fear of blowing a speaker, taxing your vehicle battery, inducing distortion or any other type of variable that may interrupt your enjoyment.

Speakers

• Superior clarity, dynamics, volume, and impact
• We guarantee our signature sound reproduction with your current door speakers (as unfathomable as that seems). This is accomplished as a result of our tuning process.

It sounds unbelievable. Really what I was impressed with was the placement of the front stage. The vocals and the strings can clearly be pulled out of the music
