Rated 4 out of 5 by from pretty decent ampUsed this Amp with The ADX shaker is pretty powerful alone, I like the design of the heat sink .I have this shaker mounted under my Futon Couch, its powerful enough to shake both the left side and the right side of the couch... it is mounted in the middle. I have it connected to a 70w DNY subwoofer Amp, that I also brought from parts express. I usded an 18 Gauge speaker wire to connect to the AMPS output located on the back side of he amp.. Then I used a male RCA subwoofer cable , and connected it to the left Mono out on the amp, and connected the other end to the Y splitter female connect on the back of the recover on the sub-woofer out.. Make sure in the recover cross over setting's are set to 40 HRZ, by default mines where set to 180. , also on the recover settings increase the subwoofer output , you will feel more shaking from the shaker this way..... also by doing this you can dail down the subwoofer valume on the back of the subwoofer so you only feel the shaking and not everyone else

Is it bad that it heats up?

Asked by: luis975
This depends on how hot it gets. This amplifier will get warm while it is being used and may be slightly warmer than room temperature when in standby mode. If it is being used relatively hard, it may get somewhat hot to the touch but this is normal.

I recently just got a ADX Maximus bass shaker, borrowed my subwoofer plate from my 12 inch subwoofer that is 150 watts @ 4 ohms. I am wondering if this would work well with the 50 watt ADX? Does it reach the lows without putting out too much power?

Hi, I currently have a KLM 200 watt sub woofer that this plate will replace. It only has one wire to connect to. Which on of the wires on the back of the new plate do I use? Also, can I run a passive woofer off this plate in addition?

Asked by: Shades
For a mono single RCA connection use the Right or the RED input.
