{"product_id":"mor-mps-hl","title":"Morel MPS Amplifier Speaker to RCA Adaptor","description":"\u003cp\u003eThe Morel MPS Amplifier Speaker to RCA Adaptor (MOR MPS HL) is the high-level to line-level input adaptor for Morel's MPS and MPD amplifier ranges — a simple, elegantly engineered accessory that converts speaker-level output from any factory head unit or OEM amplifier into a line-level RCA signal compatible with the amplifier's RCA inputs, enabling plug-and-play integration with factory source units that do not provide a dedicated pre-amplifier RCA output. The MPS HL makes Morel Performance Series amplification accessible to vehicles where no aftermarket head unit is installed, without requiring a separate standalone line output converter or any modification to the vehicle's original audio system.\u003c\/p\u003e\u003cp\u003eThe MPS HL incorporates a built-in 50Ω resistor network that performs a critical function beyond simple signal attenuation: it ensures that the factory head unit or OEM amplifier continues to see an appropriate load impedance on its speaker outputs after connection. Many factory audio systems use output load sensing to detect whether a speaker is connected and to maintain normal operating behaviour — without the 50Ω resistor, removing the OEM speaker load to connect directly to an aftermarket amplifier can cause the factory system to enter error states, mute outputs or behave unpredictably. The MPS HL prevents all of these issues, providing a clean, stable interface between the factory system and the Morel amplifier. Compatible with all MPS and MPD amplifiers that accept high-level speaker inputs.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpeaker-level to RCA conversion for factory head units\u003c\/strong\u003e — enables MPS and MPD amplifier integration with OEM source units that provide no pre-amp RCA output\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in 50Ω load-sensing resistor\u003c\/strong\u003e — maintains correct speaker output loading for factory head units and OEM amplifiers; prevents error states, muting and abnormal behaviour in load-sensing factory systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSimple, clean interface\u003c\/strong\u003e — connects factory speaker outputs to amplifier RCA inputs without a separate line output converter or vehicle modification\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible with MPS and MPD amplifier ranges\u003c\/strong\u003e — including MOR MPS 5.950, MOR MPS 4.400, MOR MPS 1.550, MOR MPD 5.550, MOR MPD 4.70, MOR MPD 4.100 and MOR MPD 1.500\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eFor the MPS remote bass control see MOR MPS R1.
