Need DSP Advice for 2020 F-150 - System

Sounds Worse Than Stock 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

What DSP should I get? Want one that works well with ford and mostly plug and play
