    Quick Wattage Question.

    Hello everyone,

    I have a quick question.

    Now i know that its kinda a nice rule of thumb to use 4awg wire up to 1000watts and higher than that use 0/1awg wire.

    I have a Hifonics NX880 amplifier right now. Now it is an 880Watt amplifer hence it being called the NX880. However that 880 watt rating is at 20hms load (220x4 @2ohms). I run my speakers at 4ohms. so the rating is 110x4 @4ohms.

    How should this amp be counted at 880watts worth of power or 440 watts?

    I plan on adding in another amplifier very soon so i was wondering about this.



    Also. You can find out your amp draw with this formula. (I know its not exact). Total Watts / Current Voltage.

    So if i were to put my amp into that formula would i say the watts is 880 or 440?

    Thanks.

    It would be 440 in your case. 8 ga would be more than enough, but since you already know you're going to be adding a 2nd amp you ought to pick up one of the 4 ga amp kits at wal-mart. Cheap and effective.

    Re: Quick Wattage Question.

    Yea, I actully already have this amp installed. And installed it with a 4awg amp kit. I am going to be adding a 2nd amp though within the next week. That is why i was asking.


    Should i just keep this 4awg wire running it into a fused distro, then run 8awg to each amp?

    Or should i upgrade to 0/1awg wire to the distro then 4awg to the amps?

    Thanks.

    I'd go 4 to 8. Bigger won't hurt anything, but it's not going to help your system any. It would just allow for a hell of an upgrade if you ever decide to.
