AFBMW ReAMP 3: plug-and-play T-harness for Audison AF bit on BMW
This plug-and-play T-harness allows installation of an Audison AF bit amplifier in BMW vehicles equipped with a RAM module. It is compatible with Standard and Hi-Fi sound systems. The OEM seven-channel amplifier connects via a 42-pin multipolar connector.
The AFBMW ReAMP 3 allows the AF Forza user to:
- Retrieve OEM source front mid/high, rear mid/high, underseat low-pass and centre signals.
- Route the AF bit amplifier outputs to each of the OEM amplifier's seven channels (Mid-Hi FL; Mid-Hi FR; WF FL; WF FR; RL; RR; Centre). The plug-and-play terminals let you choose which AF bit output connects to each of the seven OEM channels, and outputs can also be bridged.
- Keep the OEM amplifier on.
The AFBMW ReAMP 3 can also be used with the Audison AP F IN ADP accessory (not included) for a full plug-and-play connection to an AP F8.9 bit amplifier.
Notes
- Designed for RAM module-equipped 676 HiFi audio packages and Audison AF bit amplifiers. Use with other products may require modifications and additional connections to the vehicle.
- 676 HiFi systems use 2Ω woofers. Do not bridge two channels into a 2Ω load — this may cause protection shutdown or amplifier damage. To use bridged channels, replace OEM 2Ω woofers with Audison APBMW S8-4.2 4Ω woofers and confirm proper bridge wiring.
- Use Hi-level input configuration #11 (2-way front + rear + centre) during the bit Drive Wizard configuration process. This is essential to correctly route the input signal to the bit processor section.
Confirm proper application
APBMW ReAMP 1, APBMW ReAMP 2 and AFBMW ReAMP 3 use identical connectors but have different pinouts. They are not interchangeable.

About the Audison APBMW ReAMP 3
From our tech experts at CEN
A plug-and-play harness for BMW and Mini.
Who it suits
BMW and Mini owners upgrading a factory system who want the work reversible and the vehicle returnable to standard. This matters most on cars with amplified or fibre-optic factory audio, where cutting into the loom is not an option.
Our tech experts advise
Harnesses are specific to vehicle, year and which factory system the car was built with, and the wrong one simply will not work. We confirm against your exact vehicle before ordering — get in touch. See car audio installation.

Frequently Asked Questions
Q: Is the AFBMW ReAMP 3 interchangeable with ReAMP 1 or ReAMP 2?
A: No. APBMW ReAMP 1, APBMW ReAMP 2 and AFBMW ReAMP 3 use identical connectors but different pinouts, so they are not interchangeable.
Q: Can I bridge channels into the BMW underseat woofers?
A: Not into the factory woofers. 676 HiFi systems use 2Ω woofers, and bridging two channels into a 2Ω load can cause protection shutdown or amplifier damage. Replace them with Audison APBMW S8-4.2 4Ω woofers first.
Q: Which bit Drive input configuration should I use?
A: Use Hi-level input configuration #11 (2-way front + rear + centre) in the bit Drive Wizard, so the input signal is routed correctly to the bit processor.
