The Modus Operandi
Years from now, a single song can bring it all rushing back, the salt air at sunset, the deep growl
of the engine, the open water, the people who mattered most.
Modus is engineered for the road, the water, and every unforgettable mile between.
About MODUS
MODUS is the car and marine audio brand of DSP Solutions, Inc., based in Oxnard, California. Our amplifier technology began with the engineers of D'Amore Engineering, who spent years developing PREACT current averaging through hands-on prototyping and real-world validation. In March 2025, that work became MODUS.
Today the MODUS line includes marine receivers, amplifiers, speakers and subwoofers, plus car receivers and amplifiers, in three families:
- Apex, our flagship line
- Mezzo, built around PREACT and ACTEQ
- Portale, compact Class D amplifiers
MODUS products are sold through authorized specialty dealers and carry a 2-year limited warranty.
Powerful, refined.
Built to perform wherever life takes you.
"I expected amplifiers of course, because that was kind of the background for what Tony did. But what I didn't expect was a full marine line, a full line of speakers and head units, that sound like they have some pretty unique features to them too that make them a little different from the rest of the competition."
Behind the Scenes
Behind Modus is a full team of builders, engineers, product, operations, sales, and marketing, aligned around one goal: bringing a new standard of performance to market and supporting it with a premium, white-glove experience.
The technology story begins with the minds behind D'Amore Engineering, who spent years refining PREACT current averaging through hands-on prototyping and real-world validation. Long before it had a name, the work was quietly tested, improved, and proven until it was ready to move beyond the lab.
Modus did not come to life on engineering alone. It took a full team to turn a breakthrough into a product you can build at scale, install with confidence, and stand behind long after it ships.
In March 2025, Modus became the public identity for that collective work. An engineering-led innovation, brought to life by a cross-functional team committed to performance, precision, and an elevated experience.
