Eight high-level speaker inputs provide comprehensive OEM integration capability, accepting the full speaker channel output from most factory head units without a line output converter. Two RCA low-level inputs and an optical digital input offer additional source flexibility, while the USB OTG port supports firmware updates and offline tuning. Morel's Speaker Load Assurance Module (SLAM) maintains factory amplifier stability throughout the integration process. High-resolution 24-bit\/96kHz DSP processing with parametric EQ, fully adjustable crossovers, and per-channel input and output EQ provides complete, system-wide fine-tuning. Bluetooth is an optional addition for this model. Start\/stop compatibility, automatic source switching, DRC compatibility, and TuneLink multi-amp tuning support make the MDSP84A a flexible, installer-focused platform suited to both OEM upgrades and custom aftermarket builds. Four amplified speaker outputs and four RCA low-level outputs support downstream signal distribution to additional amplifiers.\u003c\/p\u003e\n\u003ch4 class=\"text-text-100 mt-2 -mb-1 text-base
