    Low pass

    Not much low pass comes through, which is completely fine. I didnt purchase it expecting it to have more without the Low Pass adjustment. But it still kicks hard like it should and it sounds great. If youre looking for more low tones to come through. I suggest getting a more expensive Kicker Amp

    Kicker is known for power and this small package does just that. I’m not surprised by the power in this small box..I’m running 1 12” comp R and I just may need to get a 2nd so I don’t blow it. Stop thinking about it and just get it, you won’t be disappointed.

    So far, so good. Works as expected. It is powering a a CompRT 8 shallow mount subwoofer with passive radiator. In my opinion, the selection of low on the input level switch should output more that it does. On low, it seems to barely put out anything.

    This was my first setup I tried matching brands for car audio, and I will say...I know why people do it. Kick subs, with kicker amps, and correct branded accessories make installation easy and loud. The shocking thing about the amp, there is no external fuse.. it's unsettling at first but the certificate of testing makes me feel slightly better..lol
