Does anyone know what size of wiring I should have going to my stereo system? I currently have 14 Gauge running about 50 ft. to it, and I was wondering if I should upgrade it to 10 Gauge or so..? I run 4 amps @ around 3000 watts total power and a 150 watt powered sub, and when I turn it up loud the lights on the front of my amps start to dim pretty badly, they almost go out.... seems like they are starving for power. I also run my computer off the same outlet 24 hours a day on a 450 watt power supply, and when I turn it off and listen to the music at the same volume level, the lights will dim a VERY slight bit less. I just thought I would ask cause maybe someone here knows what I should do so I don't burn down the house. It doesn't help that the electrical system in my house is not up to code (14 Gauge wire on a 20 Amp breaker). Any help you can give me is greatly appreciated! Thank you!
