Product Research

Features

Mounting: The T3-BMW-SUB fits as a direct replacement for the factory under-seat subwoofers in select BMW 1 Series, 3 Series, and X1 models. T3-BMW-SUBs are packaged individually, so you will need to purchase two.

Wiring: The BMW factory wiring harness plugs directly into the T3-BMW-SUB frame.

Magnets: The T3-BMW-SUB subwoofer uses a neodymium magnet to minimize size without giving up magnetic field strength.

Klippel Verified: The Klippel distortion analyzer, a device that uses a laser and sophisticated software to do large-scale analysis of drivers in motion, lets Rockford Fosgate optimize the speaker's motor structure, voice coil alignment, and suspension to yield the best possible performance.

Customer Q&A

Q
Crutchfield asked: Why did you buy this?
A
It seems that this product will fit my BMW 428i xdrive Grand Coupe. If it doesn't I will return it. Crutchfield has always done right by me and also stands behind their product. [ M  Aug 30, 2018 ]

Q
do I need an external amp? I see plug and play but where does the car get 600w from?
[ Bryan  Jun 08, 2019 ]
1 answer
A
This subwoofer will work with the OEM amplifier. However, if you wanted to get the most out of it, you could put an external amplifier behind it pushing ~150 watts at 4-ohms.
