Install Under the Front Seat
These amplifiers are so compact, they can even be installed under a seat! That’s right, put 1,000 watts under a seat, instead of filling up the boot. The controls on the front are still accessible.
Compact enough for under-seat installation.
Convenient controls and terminals make installation easy. Put the mono amp under one seat and a fullrange amp under the other seat to hide away the entire amplifier system.
Low Resistance, High Current Speaker Terminals
When you disconnect an amp it is hard to connect again because you don’t know the polarization, but the PDX amps eliminate that problem. You just plug the speaker cables into the terminals – you can’t do anything wrong.
- Error-free connections.
- Much faster and easier.
- Convenient installation with pre-wired connectors
Same Power Output into 2Ohm and 4Ohm
The ability to provide the same output to 2Ohm and 4Ohm provides greater system building flexibility.
- Mono amp has two subwoofer connectors, making it easy to add a second subwoofer.
- Same amount of power used to drive one 4Ohm speaker can drive two 4Ohm speakers when they are wired in parallel to create a 2Ohm load.
- Efficient way to get more dynamic bass.
Full Range Class-D Amplification
Class-D amplification provides extremely high efficiency, with power losses much lower than with other types of operation. The PDX amps set new benchmarks for performance and accuracy. They use an advanced power supply, custom DSP processor and a true digital Class-D circuit for superior power production and efficient operation.
Layered Installation
All of the new PDX series amplifiers share an identical form. Using the removable 1” diameter trim caps from the top of the amplifiers, the amplifiers can be vertically stacked on top of each other and share one set of mounting holes — an industry-first installation option.
