Alpha Extreme AMCA-C620.5: All-in-One 5-Channel Power That Fits Your Brand Vision

If you’re offering your customers a full-system upgrade—front stage, rear fill, and a dedicated sub—the Alpha Extreme AMCA-C620.5 gives you a single, high-performance solution to cover it all. With four channels of clean A/B-class sound and a dedicated subwoofer channel that delivers serious low-end punch, this amp simplifies installs while elevating the sound signature of your entire brand.

• You can say to your customers:
  “You don’t need three amps to get great sound. This delivers 90W x 4 at 4Ω for speakers and 260W x 1 for sub, or upgrade to 135W x 4 and 500W x 1 at 2Ω if you want full dynamic power. Whether it’s metal, jazz, or hip-hop, the system stays clear and heavy—with less than 0.05% THD.”
• You can say to your tuning-savvy users:
  “Dial it in like a pro. With variable HPF and LPF from 50 to 250 Hz on the full-range channels, bass boost up to 15dB between 40–100 Hz, and phase adjustment from 0° to 180°, this amp gives you total control across every zone. Set crossover points, match phase, and sculpt tone for the whole car.”
• You can say to your installers:
  “Simplify your install without compromising performance. This amp replaces multiple units in one housing—21.38 x 7.56 x 2.32 inches—saving space in compact cars and SUVs. With 150A external fuse protection and RCA input compatibility, integration is fast, clean, and safe.”
