Harness/Amp Prep for Dedicated Sub Amp

Your O+ Dedicated Subwoofer Amplifier has been received separate from your O+ Sound Solution. For most convenience, we advise performing the following steps outside of the vehicle before starting your installation:

Two Power Wires

Our New Harnesses are made for scalability.

  • If you’re performing  our single Multi-Channel DSP Power Amplifier, you will be using the power wire labeled “A”.
  • The "B" power wire is for our Dedicated Subwoofer Amplifier option (SP). Our recommendation is to run both power wires all the way to the battery, but only connect  the power wire labeled “A”. 

6x9 Woofer Magnet Size

You'll notice that our New Front 6x9 Woofers (32-2015) have what is perceived to be a "smaller" magnet. The good news is you received the correct product and it exceeds the performance of it’s predecessor (as seen in our installation video). You have received our New 6x9 Woofer (32-2015) featuring Neodymium Magnet(s). This upgraded magnet affords us better magnetic density with higher power saturation limits and performance as the traditional magnet, only lighter and a smaller footprint when it comes to installation (eliminating the need to use spacers to clear the window assembly on some installations). 

Tweeter has no connector

Your O+ Tweeters have come equipped with speaker leads and utilize your factory speaker connector. The process of performing this needed pin swap can be viewed in the below video of the process. For best results use a Pick-Tool or Precision Jewelers Screwdriver.
