The AP1WAMP Parking Tones Amplifier Module enables parking tones (reverse beepers) to be amplified when installing an aftermarket headunit in compatible vehicles. The module has adjustable volume control so the parking tones can be set the desired volume level. The module can plug directly into the Aerpro BA/BF Installation Kits (FP9750GK/SK) and can also be hardwired to compatible Aerpro SWC harnesses (models with bong box reverse beeper retention). It has a 3.5mm audio out socket that can be connected directly to an external speaker or Aerpro/Connects2 Bong Box and also comes supplied with a lead that can be hardwired to an external speaker. External speaker or bong box required, this is simply just an amplifier module.
