Need DSP Advice for 2020 F-150

Vehicle: 2020 Ford F-150 XLT (Non-B&O, no factory amp) Current Setup: • Skar TX65 front, TX69 rear speakers • Skar RP-75.4AB (4-channel amp) + RP-1200.1D (sub amp, no subs yet) • Factory head unit → LOC → amps → factory wiring to speakers Problems: • Painful harsh highs (Ford’s factory EQ boosts treble) • Bass disappears at volume (Ford’s bass roll-off) • System sounds worse than stock because LOC just passes factory EQ garbage

Want a DSP that’s mostly plug and play and works well with ford!
