Power 400 Watt Class-ad 4-Channel Element Ready™ Amplifier TM400X4ad
Power 400 Watt Class-ad 4-Channel Element Ready™ Amplifier TM400X4ad
The TM400X4ad is a powerful and compact 400 Watt 4-channel amplifier. The amplifier features our proprietary high efficiency Class-ad topology for maximum power, sound quality and efficiency in full-range amplifier. It also integrates our patented Constant Power technology which results in up to 25% more output power. Top mounted controls feature our patented C.L.E.A.N. circuit to easily set your gains, integrated low-pass crossover, and our famous Punch EQ.
The amplifier also features high and low level inputs combined with our differential inputs to eliminate incoming noise. It can also provide a remote-out trigger when using high level inputs. Dual fan cooling, real time thermal monitoring and dual extruded heat sinks maintain heat dissipation even at high outputs keep the amp cool.
In addition to the conformal coated pc boards, the Element Ready™ design ads protection against water, dust and UV rays, making it great for multiple applications where it could be exposed to harsh outdoor environment.

Just installed
I just installed this on my 2011 Street Glide weekend and the improvement in the sound quality is great. I have noticed a big difference in the level of the volume between the radio, Bluetooth streaming from my phone, the thumb drive, and satellite radio. The radio and satellite radio sound is too loud on volume level 18-20. When I stream from my phone or play a thumb drive I have to turn up the volume level up to 30 -40 to match the volume of the radio. Also, I am a little worried that the amplifier gets very hot to the touch and the fan has not turned on. I will let you know if this becomes an issue. Very easy to install. They recommend using 8 gauge wire for the hot and ground wire. It's a little difficult to work with if you use "True" 8 gauge OFC wire. especially try to connect the hot and ground to the adapter that fits into the amplifier.
