    Can 8 awg power a 750w amp?

    OK,

    Right now I am running a US Acoustics 1000D amplifier off of 4 gauge wire. The amp is supplying a 12" Eclipse Titanium with 750w RMS at 2 ohms. This is a class D monoblock amp. As of now, this is the only thing running off of the my battery, there is a inline fuse 80A about 6 in from the battery and then 2x40A fuses on the amplifier.

    But I am adding an Audiocontrol Epicenter to my setup, so I will be needing to split that power cable to something else. I have distribution and power blocks that accept 4 awg inputs and 8 awg outputs. I just realized that would mean halving the size of the wire going to my amp. The Audiocontol device only takes a 1 amp fuse so it will not be drawing very much power, 8awg will be fine, but I am unsure if my amp will be alright with 8 awg power and grounds.

    So my question is:

    Will that amp require more current than 8awg wires will be able to handle?

    If not, I know my amp can run on 6awg wire, where can I find a distribution block that accepts 4awg or larger and outputs at least 6awg?

    Comon, gimme a hand, remember how anxious you were to install once you got your stuff!

    THANKS

    OK so your saying that 8awg cannot handle the current required to produce 750w. That was pretty much what I was thinking, it just ***** that I have to upgrade my distos and power blocks and buy more wire ect.

    You could run a separate 12-16 awg wire for that epicenter. and then just run the 4 awg to the amp.

    As long as the 8 ga wire is kept short you're fine.
    4 feet of 8 ga is capable of safely passing MORE current than 12 feet of 4 ga.

    There are several very useful wire calculators on this page.

    Re: Can 8 awg power a 750w amp?

    I just got the Audiocontrol Epicenter, and the power, and ground inputs are tiny (well compared to 4 or even 8 awg inputs) so I will be going with something even smaller than 10 awg. This will definately not be drawing very much current, so I don't really have to go all out in the wiring upgrades.
    -thanks
