Precision Power is proud to present the boldest alongside the tallest generation PowerClass Vertical Amplifiers. Newer vehicles manufactured today aren’t getting any bigger. Finding a mounting location or taking up less floor space with traditional amplifiers is getting challenging; with Vertical PowerClass, you can mount behind truck seats or vertically standing up in trunks or rear cargo areas on cars and SUV’s

Technology is constantly advancing contemporary materials, new engineering techniques, and technology itself. PowerClass amplifiers represent what audiophile car audio can be. Unparalleled sound quality stems from multiple factors; top quality toroidal transformers, Sanken® transistors from Japan, and low tolerance Wima® resistors and capacitors from Germany, combining components for one of the highest quality amplifiers Precision Power has produced to date. The preamp section is exceptionally detailed with well-built crossovers; high pass, low pass, and subsonic frequencies can all be adjusted behind the removable front panel. To ensure that reduced or noisy input signals do not ruin the amplifier’s output, we use balanced RCA inputs for maximum clarity.

PowerClass is beautiful, chiseled, and its vertical stance complements its heart & soul. Each amplifier is secured to its forever home by a concealed, surface-mounted proprietary bracket that locks into the chassis in multiple locations. Confidently display your most recent family members in almost any location, alongside a wheel well, storage cubbies, or even upside down from the ceiling if you’re into that sort of thing?
