The BLADE BP Series Amplifiers are designed with our "Live, Loud and Play Hard" motto. All amplifiers have built-in OEM line converters with RCA inputs that can take a high-level speaker signal at up to 9 Volts directly in. By sensing the DC off set of a factory radio it can activate the ATO (Auto Turn On) feature and convert the 12V turn on into a 12V switched out.
Features:
- Built-In OEM Line Converter
- 2 Ohm Stable Design
- Class A/B
- Mil-Spec PCB with SMD parts
