2010-2017 BMW 5 7 Series X3 Top-HiFi LEAR Audio Sound Amplifier 9248552 OEM

Condition

Used

This is a genuine factory-original BMW Top-HiFi (Premium Sound System) audio amplifier manufactured by LEAR. It has been carefully removed from a donor vehicle, bench-tested, and verified to be in excellent operational working order. All audio output channels are clean, clear, and balanced with no distortion or static. The aluminum cooling fins are intact, and the pin connector blocks are completely straight, clean, and free of corrosion or moisture damage. As a pre-owned electronic module, minor cosmetic surface wear, scuffs, or faint oxidation marks may be present on the outer casing, but nothing that impacts performance.

Description

Up for sale is a genuine factory-original BMW Top-HiFi DSP sound amplifier module, specifically matching part number 9248552. Manufactured by LEAR, this high-output audio processing computer acts as the primary power source for your BMW's premium multichannel speaker array, driving subwoofers, mid-ranges, and tweeters while managing spatial theater acoustics.

BMW factory amplifiers are highly vulnerable to localized trunk hardware issues. Worn taillight gaskets, clogged sunroof drain tubes, or trunk lid seal leaks commonly cause moisture to pool directly into the rear left audio compartment cavity. This water ingress short-circuits the internal amplifier circuit board, leading to common failure symptoms like a complete loss of cabin sound (no radio audio, no Bluetooth, no navigation audio), loud random popping or static noises through the speakers even when the car is turned off, an un-responsive iDrive audio menu, or rapid vehicle battery drain. Swapping your water-damaged module with this clean, dry, original factory replacement unit safely restores your premium cabin sound fidelity.

Important Fitment & Programming Notice: This amplifier is engineered exclusively for BMW models built with the Top-HiFi Premium Audio Option. It will not function in base-tier standard stereos or vehicles equipped with the optical fiber Harman Kardon Logic 7 setup without matching wiring infrastructure. Please confirm that the part number on your original module's sticker matches 9248552 or one of its direct listed interchanges. Additionally, because this module registers directly to the vehicle's MOST fiber-optic network loop, a brief VIN-specific coding session using a BMW specialized service tool (like ISTA/P or ESYS) may be necessary upon installation to successfully configure the amplifier to your vehicle's specific cabin acoustics map and options list.
