The tweeter gets highs, the door gets midbass, another channel may carry a different band, and none of those outputs by itself contains the whole musical signal. Feeding one of those channels straight into an aftermarket amplifier or processor leaves information missing before tuning even starts.\u003c\/p\u003e\u003cp\u003eThe SRI is built for that problem. It accepts multiple factory speaker-level channels and can sum the band-limited pieces back together into a usable signal path for the aftermarket system.\u003c\/p\u003e\u003ch3\u003eWhat it solves\u003c\/h3\u003e\u003cp\u003eIf the factory system has already divided the music with its own crossovers, EQ and amplifier routing, simply adding an amplifier does not restore the missing bands. The SRI gives the installer 2-, 4- or 6-channel high-level input capability and selectable summing or pass-through operation so the incoming architecture can be rebuilt around the actual vehicle.\u003c\/p\u003e\u003cp\u003eSetup indicators help identify the usable signal and simplify level adjustment instead of relying on guesswork. ARC also provides a separate auxiliary RCA input with remote level control, allowing a second source to be integrated when the system design needs it.\u003c\/p\u003e\u003ch3\u003eIntegration features that matter\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e2-, 4- or 6-channel high-level input\u003c\/li\u003e\n\u003cli\u003eSelectable summing or pass-through operation\u003c\/li\u003e\n\u003cli\u003eHigh-impedance input design to work with modern factory amplifier outputs\u003c\/li\u003e\n\u003cli\u003eBTL input auto-detection\u003c\/li\u003e\n\u003cli\u003eSignal-sense or conventional remote turn-on\u003c\/li\u003e\n\u003cli\u003eSelectable signal-ground isolation\u003c\/li\u003e\n\u003cli\u003eSetup LEDs and calibration controls\u003c\/li\u003e\n\u003cli\u003eAuxiliary RCA input with remote level capability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSRI vs. NGM vs. BXM\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eChoose SRI\u003c\/strong\u003e when the factory signal is split across several speaker channels and needs to be recombined before the aftermarket system can use it properly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eChoose NGM\u003c\/strong\u003e when the signal is otherwise correct but carries standing hiss or background noise that needs to be gated during quiet periods.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eChoose BXM\u003c\/strong\u003e when the signal is usable and the goal is perceived bass extension rather than factory-signal reconstruction.\u003c\/p\u003e\u003ch3\u003eManufacturer specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eInput channels: 2 \/ 4 \/ 6 high-level\u003c\/li\u003e\n\u003cli\u003eMaximum input: 19 V RMS\u003c\/li\u003e\n\u003cli\u003eMaximum output: 8 V\u003c\/li\u003e\n\u003cli\u003eGain range: ±20 dB\u003c\/li\u003e\n\u003cli\u003eFrequency response: 10 Hz–33 kHz\u003c\/li\u003e\n\u003cli\u003eTHD: 0.006%\u003c\/li\u003e\n\u003cli\u003eInput impedance: 38 kΩ\u003c\/li\u003e\n\u003cli\u003eCurrent draw: 200 mA\u003c\/li\u003e\n\u003cli\u003eDimensions: 8 × 5.25 × 1 in.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eSystem note:\u003c\/strong\u003e summing can reconstruct frequency bands that are present across the factory outputs, but it cannot create information the OEM source has removed entirely.
