I am planning to wire my single sub 400rms svc to my amplifier 400rms x 1 @4 ohms. My car model is 94 mitsubishi lancer. how many AWG ( gauge) should I use? Like for Power, ground, speaker wire. I just want to have the full potential of my sub and ampli.For my 2nd question: if I decided to put a 2nd sub wired it on the same amp making it 800rms x1 @ 2 ohms. (my amplifier is a class d mono 1600 watt peak by the way) should I need to use a capacitor?Thank you
biggest wire you can afford to power the amp...and dragon breath above drives aroud with headlights dimming every time the base hits...that is why we us caps..to keep large current draw from hitting the battery and alternator and dimming the lights....or dragon just don't have a system that will dim his head lights lol....sorry dragon just poking fun....but if i don't run caps my headlights look like strobe lights at night
The power wire and ground wire should be the same guage. Here is a simple calculator to help you out. Good luck!
Well a capacitor is always desired for me...even if not to help the amp...it also helps your alternator/battery. Most class D amps can handle 2 ohm mono...actually most of them can handle 1 ohm mono...as for wiring. It depends on how many amps your amplifier's fuses are. If your amp is drawing more than 50 amps I'd say 6G or thicker. less than 50amps then 8G is plenty. The wattage the amp says it puts out is misleading...the fuses on the side of the amp tell the whole story. 12g speaker wire should take care of you as well. If the amp were on the larger side (requiring 6G wire or thicker) then 8G speaker wire would be a good idea.
