Other than a the obvious fire hazard. Is there any performance loss.

For example, using an 8 gauge wire, where the proper wire is a 4 gauge.

 

it'll become a bottleneck for current in that it cannot supply the needed amount through the small sized wire...but yeah Fire is a big one too worry about, do you really need more reason

 

just curious, haha

 

To small a power wire WILL cause the power supply in your amp to die pre-maturely.

 

Is it possible to use a guage that would be too large? Say the aplication calls for 8guage wire and you drop in 4 guage. will this cause an issue?

 

nope other than your amps power and ground terminals might not accept that big of wire

 

in general I would use 4 at least my friend is gonna be using 0/1 gage wire. it all depends on how much your drawing.

how much can 4gauge carry?
how much can 8 gauge carry?

I searched google, but all i got was junk.

 

it depends how long the wire is

Well I am gonna be running both 1000 watt amps in my T/A. I plan on putting 4guage wire from the bat back to my amps and then using a distribution block and using 8 guage wire to go from the distro box to my amps and then using 4 guage from the amps to the grounds...I think that will work. The wires won't be long between the amp and the block.

 

Wire Gauge Current Flow Max Total Amp Power
Class AB (60% eff) Max Total Amp Power
Class D (75% eff)

8 awg 52 amps "430 watts" 537 watts

Does that mean my amp will only be able to make 430 watts max if 8 gauge power wire is run to it?

4 awg 131 amps "1084 watts" 1355 watts

If thats the case then i am starving my amp of power.

 

I would not run 2 1000 watt amps off of 4AWG, I would use at least 2AWG...
