Product Description
This is where precision tuning takes over. The Audison Forza AF C8.14bit DSP amplifier powers the APBMW X4E coaxials front and rear and APBMW S8-4 underseat woofers, while we configure EQ, crossover points, and time alignment specifically for your BMW interior. The result: balanced, coherent sound across the whole cabin that simply isn’t possible with non-DSP amps.
