Get the LITE for a daily car. Get the PRO for a loud or competition build. The PRO adds signal analysis: clip detection, an RCA oscilloscope and a spectrum analyzer, so you can spot a clipped signal before it hits your amps. It also adds an amp heat sensor and can turn your amps off if your voltage drops or they get too hot. The 6-channel PRO also has a live THD analyzer and sweep tools.
