6x9 Subwoofer vs 6x9 Speaker: Why the MBW690 Won't Go in Your Lids
Search "6x9 woofer" or "best 6x9 speakers for bass" and you'll find two different animals. A 6x9 lid speaker plays the full range from a stock lid opening. The MBW690 is a dedicated 6x9 subwoofer. MMATS rates it from 28 Hz to 250 Hz with 4.5" of mounting depth, and it does not fit standard Harley-Davidson speaker lids.
Want more bass out of the stock lid openings? Look at 6x9 mid-bass and component speakers built for lids, like the Cicada CXK69 component kit. Want real low end from a custom enclosure? That's the MBW690's job. Compare more in motorcycle subwoofers.
Powering a 6x9 Sub: Amp, Crossover and Enclosure
The MBW690 has a single 4 ohm voice coil rated 300 W RMS. Give it one amplifier channel that makes about that much at 4 ohms. Most builds use a mono amp, and a mono amp is never plug and play: it needs its own fused power run, ground, signal and a tune. Shop motorcycle amplifiers.
The sub tops out at 250 Hz, so cut it off with a low-pass filter on the amp or a motorcycle DSP and let the lid and fairing speakers handle the rest.
Plan the box before the sub. Mounting depth and enclosure space decide whether this works on your bike. Talk to us first.

Do I need a crossover with a 6x9 subwoofer?
