I've had my Buttkicker for more than 20 years. No problems at all. If mine was to quit today, I'd have to order a replacement tomorrow.

4 buttkickers in parallel series but doesn't have the kick of my old k1000 amps.

is there another way to wire? did I do something wrong?

Excellent Amplifier, what i like most is how simple it was to install and the customer service was right on point. I wired 8 Buttkicker minis into 4 theater chairs and they work great, also , they are easy to adjust to my preferred vibration. Love the Amp and would highly recommend it to others who want to take their Home Theater to the next level. Thanks for all the help and a great product!

big power, great thoughtful design for auto on/off, and volume remote.

If youre running buttkicker systems in your theatre, this is the perfect amount of power and brains to operate the system. Smoothly. I'm happy I purchased it and it is also what buttkicker designed just for my setup.
