The PM100X1 amplifier uses our patent pending BTL technology to provide you a very unique amplifier solution. This single channel amplifier utilizes the speaker output of the radio to not only provide the audio signal it needs, but also the power that runs the unit. This is done through a combination of the DC offset voltage commonly present and the audio AC signal itself.
Initially, it uses the DC offset voltage for its turn on power as well as primary amplification power. As volume is increased and the output power demand rises, the amplifier begins sharing the power load between the DC and AC signals. Once high volume is reached, the majority of the amplifier's power is provided from the AC signal only and is supplemented by its intenal storage bank.
This design allows it to actually charge its capacitive bank on the downside of the AC signal wave which is essentially unused power anyway. It also presents no more load to the radio than a standard 2 or 4 ohm speaker would thus keeping the radio amplifier circuit safe from low impedance conditions. This design allows the amplifier to be connected to a radio with a rated 20 watt output and produce up to 100 watts dynamically. The unit also features a 2/ 4 ohm input switch to match the amplifier to the output impedance rating of the radio circuit. For speaker protection, we incorporate and selectable high pass crossover with setting at 60, 80 and 100Hz.
In rare cases there is not enough DC voltage present to power the amp at turn on so an add on B+ wire is included and can be tied to other lower current circuits in its proximity. This design makes the amplifier ideal for OEM or aftermarket upgrades without having to use physically larger amplifiers as they can be hidden in the dash or doors of the vehicle. It is also IPX6 rated for those installs where moisture may be present.
