Plug & Play T-harness for replacing the BMW factory amplifier

OEM-style 42-pin multipolar connector (inserted in place of the factory amplifier)

BMW models from 2004+ with the HI-FI 676 sound system, and 2014+ models with the Harman Kardon 674 (low) system (late E60, all E9x/E8x, F3x/F8x, up to iDrive 7)

For Audison AF bit / AP bit series amplifiers (AP F8.9 bit needs the AP F IN ADP adapter for full plug & play)

Brings out preamp-level front, rear, under-seat woofer and center (if fitted) signals from the OEM 7-channel analog amplifier, plus B+, GND and 12V remote turn-on leads

APBMW ReAMP 1, ReAMP 2 and AFBMW ReAMP 3 share the same connector shape but different pinouts and are not interchangeable; not compatible with RAM-based AFBMW ReAMP 3 vehicles or MOST-equipped 677/688 systems; vehicles with an artificial exhaust sound generator may additionally require the AP BMW ASD BYPASS module
