You got questions?

Do you make product for other cars?

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

Dealer or DIY Install?

Both! We pride ourselves in creating plug and play solutions that we believe any one can install. (Link to Warranty Information on FAQ) Note: Be mindful of essential tools necessary to complete installation. Please review our installation videos - Check out our installation page.

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).
