i cant say that i agree with any of that. i have a 2000 ford tuarus wit a memphis audio mojo 15" 1000 watt sub and a sony xplod 1200 watt amp and i spent $30 on a 8 gage wiring kit from walmart and i have one of the hardest hitting systems around lilburn. i have had zero problems with it. one suggestion i have to get rid of feedback is to run the amp REM and +12V wires down one side of the car and the rca wires down the other side of the car.
