OEM Audio Plus


Common Questions. Answers Given.

Do you make product for other cars?

Currently serving Jeep, Toyota, Subaru and Ford. Our policy is to meet market demand as warranted. Feel free to petition your model today!  

Who performs the Install?

90% of our owners perform the installation themselves (and/or with the help of friends/family). We pride ourselves in creating plug and play solutions that we believe anyone can install. Please review our installation videos – As found on our installation page. Be mindful of essential tools necessary to complete installation.

Not wanting to perform the install yourself, we understand. Contact us to find an installer in your area or get us involved in finding an installer in your area that can assist. 

Install time?

Our systems have all been proven to be installed in 3 to 5 hours. It is safe to anticipate approximately 3 hours for a complete installation.

Factory Warranty is not affected if installation is followed according to OEM Audio Plus installation guidelines. All OEM Audio Plus components meet OEM specifications and include 3 year/36,000 mile warranty whether installed by an Authorized Dealer or if you opt to Do It Yourself.
Does it work with aftermarket radios?
Yes! Our products are calibrated for optimal performance using your factory or aftermarket head unit. We tune each sound solutions specifically to the output characteristics of YOUR head unit – so be sure to let us know which radio you have when ordering.
Can I buy the sub separately?

At this time we do not sell our subwoofers separately. This is because O+ specializes in delivering GUARANTEED results in terms of installation, sound and reliability (a promise we can only guarantee with our close-loop packages designed, engined and tuned for each specific vehicle).

Installation Instructions?

You will find the most up-to-date Installation Content on the Install Section of the website. 

Different Amplifier Connector

Please Select Your Generation Amplifier Below for Connectivity Instructions:

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 6×9 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 6×9 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). 

Lead Times Are Estimations

Each of our Sound Solutions is made specifically for you based on your provided configuration notes when submitting your order. None of our products are mass-produced. All lead times are estimates and rely on various factors. We are currently experiencing high demand, and longer-than-usual lead times as many companies are within our industry. Our team is actively working to ensure that the wait is minimal and that the results of what is delivered are unmatched. Our job is not complete until your System is delivered and performing as intended.
