    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

    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!

    What a nice amp.

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

    Great power and output

    Loads of power from a small package! I am running this amp at 300w 2ohm and it pounds on a JL W1 10” in a sealed box. It is easy to hook up and set was a breeze. I paired it with the matching key 200.4 The only negative is not even about the amp. I purchased it open box “excellent” and it had some noticeable scratches. I would have purchased anyway had I known just to save a few $.
