Welcome to the SMD forum!
I had sold my sundown audio x 15 about 5 years ago. along with my rubicon 2500.1. I am now wanting to get back in the game. I have a 07 infiniti m45. Right now on stock electrical I can safely run 1296 watts. I am looking for a 1500 - 2000 rms amp. A single 15 or 18 to match that power. I will also be needing 1/0 welding cable for my runs and to do the Big 3 on this car. I am located in Fort Myers, FL 33916. If after shipping me buying your preowned amp / sub is 50$ away from me just buying it new I am not interested.
