🧠 Pro Tips

  • Use high-pass filters for smaller speakers: This prevents excessive low bass from reaching mids or tweeters, reducing distortion and improving clarity.

  • Set bass boost moderately (e.g., 2–4 dB) to enhance punch without overpowering your sound stage.

  • Match amp power to speaker ratings: Pair with speakers that can handle ~75W RMS for clean, distortion-free audio.

  • Run quality power and ground wiring with proper fusing to ensure stable voltage and protect your system.
