Hertz Crossover

Hertz Crossover

The passive crossovers in this speaker kit have been modified and pre-wired for you to be plug and play with your ‘14 & up Harley bagger. Use velcro or double sidded acrylic atachment tape to secure both crossovers in place. There are two good locations for the crossovers. Place one crossover directly behind the small throttle side gauge. Place the second crossover on the throttle side of the factory radio, next to the phone box in the dash.

There are three pigtails on each crossover.

  1. Woofer plug. This is a black 2 pin molex plug that will connect directly to the speaker pod and provide signal to the 6.5” woofer.
  2. Tweeter plug. This is a white 2 pin plug that will connect to the matching plug that has been pre-installed on the tweeter for you.
  3. Copper and blue speaker wires. These should be connected to the speaker output of your amplifier. Copper is negative and blue is positive.

Mounting the Speaker Grill
The tweeters have been pre-installed for you in each speaker grill. Be sure to locate the six (three each side) screws that are supplied in your speaker kit to attach the grills to your inner fairing. The tweeters can be rotated inside of the grill so that the Hertz logo is right side up and level. The tweeter speaker wire should be positioned to run straight down and will fit between the speaker grill and your new 6.5” woofer. There is about 3/16” of space between the speaker grill and the woofer once the woofer pod is put back in place. This is enough room for the wire to pass between the two without issue. Be sure that there is not tension on the tweeter wire. If the wire is pulled tight it can make excessive contact with the surround of the woofer.

Amplifier/DSP Crossover Settings
This speaker system is capable of playing down to 45 hz however in this application it is advised that you high pass these speakers at 100 hz with a crossover slope of 12db.


Harley Bass Boost.
Harley radios have a very large amount of bass boost programed into the radioit’s self. It is highly advised to either use a good sound processor to counter this frequency curve or to have your bike flashed or a combination of both. Not compensating at all for this can cause damage to your speakers over time. Particularly if you play at very high volume levels. An alternative to using a DSP or having your bike flashed is to lower the bass level control on the radio and also increase the high pass crossover on your amplifier to 150 hz. This is a work around that can get you satisfactory results, however a good DSP is the better route to take if possible.
