F10 Add-A-Sub (677, 688, 6F2)

$2,195.00

Add-A-Sub Upgrade Level Three for BMW F10 Sedan

The highest-performance sub-bass add for the F10 sedan available without losing cargo-floor area!

Add a subwoofer without modifying your car! This is a plug-in, bolt-in upgrade, reversible in future, and adds the sub-bass notes that the underseat woofers struggle to play. Those woofers are still playing critical mid-bass notes, which won’t escape the F10’s tightly-sealed trunk – they work together to get you the extended low-end response that’s impossible from the underseat speakers.

This isn’t a “bump” audio package – it’s a high-fidelity bass package which works in conjunction with your existing premium sound package (HK, B&O, or unbranded “677 DSP Professional”).

  • Corner-loading gets you more output than a comparable “on-the-floor box”.
  • The “OE-Look” upholstery has been hand-dyed to match your BMW trunk
  • As a Musicar design element, the woofer is recessed 19mm from the outer edge
  • All mounting hardware and wiring is included
Level Three
  • 600 watts RMS for the subwoofer
  • amplifier rack (installs out of sight under floor)
  • active crossover filter
  • matching black mesh grille
  • plug-in integration harness prewired to high-voltage signal attenuator
  • loaded enclosure with a 10-inch very-high-output subwoofer driver (Made in the USA!)

Description

Application Notes

This package fits vehicles with 677 DSP professional, 688 Harman Kardon sound, and 6F2 B&O. It does not fit the F10 Hybrid.

The signal is interfaced with using a plug-and-play harness (no cutting) which we prep for the specific system. The signal is routed through a high-voltage-capable attenuating buffer amplifier (the H/K amplifier can reach peaks of 28 volts to the stock 8-ohm woofers, so it’s important to reduce that signal to a level which the new amplifier can handle).

The Level Three package sends 600 watts of continuous RMS power to a very-high-output 10-inch subwoofer driver. This is the highest-performance plug-and-play subwoofer add package in existence for the F10.

The installation is plug-and-play to the H/K or B&O amplifier, and our equipment rack bolts into existing trunk holes.

The enclosure mounts using an existing expanding-insert hole and we provide a new, longer OEM BMW insert.

Our harness includes a center-delete loop, which allows you to easily test our recommended “surround off, center delete” setup for the H/K audio package.

Please keep in mind that the F10 has a highly sealed trunk. We recommend removing the ski pass plate and insert, and best bass transfer occurs with the rear-seat armrest folded down.
