I bought this amp to run a couple subwoofers in my home theater setup. I have it running two 18" subwoofers at 2 ohms. The amp does its job flawlessly and barely gets warm. Plenty of power on tap for those loud action scenes. The only problem I have with this amp is I have to keep it away from my receiver because it interferes with radio reception. This amp is a great buy.

What is it? A single-channel (mono) amp specificially for ButtKicker tactile transducers.

What does it do? Powers ButtKicker magnetic pistons that you can bolt under your floor or inside your sofa/recliner to augment your bass and special effects. That works really well and is much cooler than it sounds.

But that's the only thing you should use it for. ButtKickers, other tactile transducers (e.g. Clarks), and perhaps subwoofers. It doesn't do high frequencies. It doesn't do low distortion - which you will never notice at low frequencies. It won't even turn on until it detects very low frequencies. This is the engine of the ButtKicker. You want this, not your receiver, to power a ButtKicker (or Clark, etc) because you need raw power that can be a bit dirty for those. Your receiver pumps out expensive clean power, and not so much of it. So you need both.

For the intended purpose, it's perfect. And, from experience, if it needs fixing, ButtKicker (Guitarhammer) just takes care of it. The absolute best customer service I've seen.

This amp is a steal for either powering subwoofers (1000 W @ 4 Ohms, 2000 W @ 2 Ohms) with genuine clean power below 120 Hz. Being not fully shielded, it should indeed be kept away from other units...and plugged into its own outlet, preferably with its own GOOD UPS (uninterrupted power supply, the heavier the better).

The Buttkicker SYSTEM (1-2 transducers per amp) is AMAZING. By itself it produces true radiation down to 5 Hz (one would need a 30+" woofer or a complex horn-loaded speaker). I have four of them, two drive Klipsch 15" subs for free-air radiation from 80 Hz (THX) down to 20 Hz and two of them drive a single buttkicker transducer, each from 5-80 Hz, so there's a TON of headroom for calibration at high levels.

BUY THIS SYSTEM, nothing else compares!

This amp just plain works, has lots of adjustability, (low and high filter cutoffs), and plenty of power. I am using it to run two 4 ohm Clack Synthesis Platinum TTs, (wired in parallel per Buttkicker's instructions), in my home theater. Gain control hasn't been turned past 1030. There might be cheaper alternatives but you won't get the filters or the power this unit has to offer. Lost one of these units to a lightning strike a couple of years back but to be honest, I don't think it was behind any protection at that time. Unit was locally repaired and returned to original operating status. The original unit and now my second unit have both been flawless in operation for some time.

this amp will power any home sub u have. easy set up,just plug it in and dial up the bass.it has more power than you will ever need. i have it hooked up to a 15 solobarric 1500 watt speaker. the most bass i have ever heard!!!!!!!!!!!!!!!!!!!!!!!!!!
