Is 4 gauge speaker wire really necessary?

[asilentfire 10+ year member]

I am looking at possibly getting the CADENCE F100-5 amp and people on Amazon are saying its rated for 4 gauge wire, and a chart I looked at said that for running 75 watts RMS I need 4 gauge wire.

Can 12 gauge wire be used on the amp? What should I look for that will work with it?

It's talking about 4-gauge power cable. The speaker terminals are probably a maximum of 12 gauge, don't worry.

Thanks, but do I need to buy a 4-gauge power cable seperatly?

Is something like this kit necessary?

Some amps on eBay say things like: 4-gauge power and ground wiring is required for installation. Contact us for information regarding a discount on select amplifier kits when purchased together with this amplifier.

amps wont come with power wire. If you already have rca's, fuses, and speaker wire, you dont need a kit, you only need to buy the power cable. If you need everything you can buy the kit or get it all separately and most likely end up with better quality.

no 4g isn't needed but I would stick with 8g at least.

I would rather get an 8 gauge or even the 4 gauge KCA from Knukonceptz rather than one of those cheap 4 gauge kits from ebay or amazon.

Or if you already have subs and decent wiring a distro block would work.

amp is fused at 90a you dont want to run that through 8ga, just run 4ga and be done.

just looked at the link yea run 4g!

def don't use 12g wire as your power or ground wires

Thanks for the link 40oz, I'm looking at this kit and its for a 4 channel amp, while mine is a 5 channel. Sorry for asking this is kind of dumb, but what else will I need in addition with this to wire the sub?

No problem bro.

Your gonna need another set of RCA cables since it is a 5 channel. Grab the Klarity RCA's from Knu as well, good quality for the price and it will match the RCA's in the kit your looking at. I have the same kit in my ride, best bang for the buck definitely.
