new system 00 s10 xtreme

[fullthrottlejunkie85]

well i have a 00 s10 ext cab and i built a ported box that is 3.13cubic ft 40hz tune and is for my two ten re audio sexd2 with mtx 1501d older amp but good, well im wanting too setup gains as good as possible till more money and ill get a dd-1 so does using a cd with 50hz or using my cell with the aux input with a youtube 50hz test tone which should i do? I do use my cell for music i have. my deck is a pioneer 7200hd so its roughly max before clip like 37-38 i think. I believe that my amp gain would be off if using a cd and then use a usb or aux input creates a boost. im confused cant u tell lol i figured since my electrical is stock id use digital mm and set at 3/4 of deck volume 50hz test tone should be like output at amp would need too be at ac voltage 46.90-47.00?
