Our take on the Blaupunkt 6902A

Blaupunkt designed their 6902A powered subwoofer to fit in your spare-tire housing, so you get bass that's out of sight. This GT Series powered sub comes equipped with two 6"x9" polypropylene woofers powered by an internal amplifier that delivers 150 watts RMS. You get a hidden powered subwoofer that really rumbles.

Product Highlights:

  • powered subwoofer with dual 6"x9" woofers
  • built-in 150-watt RMS amplifier (300 watts maximum)
  • frequency response: 20-120 Hz
  • dimensions: 22-1/2"W x 6-3/8"H x 22-1/2"D
  • warranty: none (Crutchfield's 60-day satisfaction guarantee applies)
  • Our 60-day money-back guarantee

I didn't expect much from this unit because it uses two 6"x9" speakers in the subwoofer, but man was I wrong!

I didn't expect much from this unit because it uses two 6"x9" speakers in the subwoofer, but man was I wrong!

Pros: Nice, deep, clear bass. Easy install, built-in gain and crossover. No need to run separate amplifier control wire. The cable that is included contains dual power wires, dual ground wires, and separate wires to hook up the speaker inputs to the amplified output of the stereo if your deck does not have preamp outputs.

Cons: Did not include RCA cable. The included cable was a little short, which forced my to have to run them straight up the middle of the car, as opposed to along the edges of the doors.

Product Research


Overview: The GTs 6902 A amplified subwoofer features a 150-watt RMS (300-watts max) amp and two 6x9 subwoofers housed in an enclosure designed to fit in the spare tire well (the spare tire is removed).

Auto Turn-on: The amplifier automatically turns on when it detects a signal on the line or speaker level inputs. After approximately 60 seconds with no input signal, the amplifier will turn off.


  • Gain: rotary dial to set the amplifier input gain; continuously variable from 300mV to 5V for the line level inputs and 1.2V to 16V for the speaker level inputs
  • X-Over: rotary dial to set the low-pass crossover frequency; continuously variable from 60 Hz to 120 Hz
  • Phase: rotary dial to set the subwoofer phase; continuously variable from 0° to 180°


  • Power: the included 10' harness has two power and two ground wires (all should be connected and the power wires should be fused at the battery)
  • Speaker Input: the included 10' harness also has left and right speaker level input wires
  • Line Input: stereo RCA jacks
  • RF Link: RJ-25 jack; not used in this installation
