Which Match product should I choose?

For a complete system upgrade, the M 5.4DSP combines five amplifier channels with a 9-channel DSP in one small unit, making it ideal where both speakers and a subwoofer need to be driven from a single amp. If you only need to power a subwoofer or a pair of speakers, the M 2.1AMP offers a switchable mono/stereo design in the same compact footprint, while the M 2FX is a straightforward 2-channel amp at a lower price point.

For wiring, select a PP-ISO harness based on the distance between your head unit and the amplifier — 1.00 m, 2.20 m, or 5.00 m options are available. BMW owners with a factory HiFi system without RAM should also consider the PP-BMW ASD-Bypass to prevent artificial engine sounds playing through the under-seat subwoofers.

Match Amplifiers & PP Cables FAQs

Q: What is the difference between the Match M 5.4DSP and the M 2.1AMP?

A: The M 5.4DSP is a 5-channel amplifier with an integrated 64-bit 9-channel DSP, suited to full system upgrades driving both speakers and a subwoofer. The M 2.1AMP is a 2-channel/mono amplifier without DSP, designed for simpler installations where only speakers or a subwoofer need powering.

Q: Which PP-ISO cable length do I need?

A: The PP-ISO range is available in 1.00 m, 2.20 m, and 5.00 m lengths — choose the version that reaches comfortably from your car radio to wherever the Match Plug & Play amplifier is mounted.

Q: Can the Match M 2.1AMP drive both a subwoofer and speakers at the same time?

A: No — it is switchable between 2-channel stereo mode (2 × 170W RMS at 4Ω) for speakers or mono mode (1 × 350W RMS at 2Ω) for a subwoofer, but not both simultaneously.

Q: What does the Match PP-BMW ASD-Bypass do?

A: It is a plug-in wiring adaptor that bypasses the Active Sound Design module in BMW HiFi systems without RAM, stopping artificial engine noise from being played through the under-seat subwoofers.

Q: Can CEN fit Match amplifiers professionally?

A: Yes — CEN has its own fitting workshop in Beeston, Nottingham, where the team can carry out a professional installation of Match amplifiers and associated wiring looms.
