A:AnswerThe amp will definitely power it if you have the low pre amp connections (RCA Female jacks) It does use a power connection and I suggest on a different circuit than the amp and make sure that the volume on your phone is way down low before the Blue Tooth connects or it will get loud quick
A:AnswerYou must have either an available RCA input (the red and white female connectors) on the back of your car stereo or, a headphone jack/auxiliary input on the front of your stereo for the unit to plug into.
If you have either of these connections then all you need to do is choose your connection type listed above, then connect the hot lead and ground wires to you stereos wore harness and, you should he good to go.
This unit will work on any old stereo as long as you have an available audio input, power, and ground.
