The Power TM400X4ad 400 Watt 4-channel ultra-compact, amplifier is built on Rockford Fosgate’s proprietary Class-AD technology, featuring Constant Power to produce the same output at both 4-Ohm and 2-Ohm impedances. Flexible vehicle integration enabled through low-level and high-level inputs with auto turn-on. Top mounted controls allow easy access to built-in crossover and C.L.E.A.N. input/output clip detection circuits. The 3-stage thermal lock extrusion with dual fan forced induction keeps everything cool while real-time thermal/protection schemes safeguard the amplifier.

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.
