  • What a nice amp.

    Tiny but effective amp. Perfect for sub requiring 500w RMS. Setup/calibration was easier that should be possible.

  • Great little amp for tight spaces

    This is an excellent amp for a subwoofer. The amp has its limitation, as the size suggests, but it is very capable, configurable. I really liked the fact that is has the option of using high signal or low signal for input, time saver!

  • Key 500.1 in MKIV supra oem amp location

    Great quality, power, and size! The setup tokes a little research but makes tuning simple. Perfect for applications where space is an issue. I have it mounted under my seat with plenty of space to spare. Highly recommend
