The HR 10 US is a 10-inch powered sub with the amp built in, slim enough to slide under a front seat. It takes speaker-level input, so it adds real bass to a factory radio without giving up any cargo space. A good fit for trucks, Jeeps and cars where a big box won't work.
Features
- Easy underseat installation
- Low-level RCA and high-level (speaker) inputs, works with factory radios
- Auto power-on with high-level inputs
- Variable gain, low-pass filter, bass boost and phase control

Does it work with my factory radio?
