OEM Add-On Amplifier Interfaces - OnlineCarStereo.com

Use the prized aftermarket stereo components you desire with any factory amplification system by installing an amp interface that makes them compatible.

Vehicle Amplifier Interfaces

For some car owners, upgrading their receiver, radio, amplifier and other stereo parts can seem like more hassle than it’s worth. This is because many OEM amplification systems are very difficult to remove — and designed to be incompatible with most replacement parts. It isn’t surprising that manufacturers would want the factory stereo left as-is, but it’s a real pain in the ear every time the music is on.

In these situations, the best solution often is to add an amp interface. Some of these accessories connect to the OEM amplifier and make it compatible with your aftermarket stereo components. Other factory amplifier modules bypass the original system altogether so you can add new amplifiers and preamps. By using your stock stereo with an amp’s interface from OnlineCarStereo.com, audiophiles will be able to set up a new system without the aggravation of removing the old one.
