What size wire do I use to powe r& ground my amp is 12 gauge ok?

 

Depends on how big the amp is. Probably need something more along the lines of 4 gauge or maybe 8 for a smaller amp.

 

if it's 100-200 watts, 10 ga. might be ok...but I'd go with 8 for good measure.....anything over 400 and I'd definitely use 4 ga.....

 

Hmm, my psychic powers are failing me.....

For real, a technical question without noting what gear
you are using is retarded.

 

If your amp will accept 4gauge get it. When it come it power wire the "BIGGER IS BETTER" statement holds true. The easier you amp get power the better it will preform. Just make sure you use the same gauge for the ground or you'll burn the amp out and possibly your car!!

 

12 gauge is ok but pretty small imo. I always run 4 gauge just in case if I ever upgrade my amp I dont have to change the wire again

 

Well all amps now a days use nothing lower then 8 gauge...

Read the manuel though

 

without knowing what the specs of the amp are, there's no way to give you a definitive answer.

 

This is true to!!

 

What makes you say this? I am an electronics engineer and I can't find any relevance between the "+" vs "-" wire guages. Are you talking about the speaker wire +/- or the amp power connections?

 

Hes talking about the power....

If your running 4gauge power wire you better be running 4gauge ground wire.

 

If your amp will take 4 ga then use it. Also you better use 4ga ground wire too. I would never use anything smaller than 8 ga except maybe on a powered bass tube which you could use 10 ga.

 

With you being an electronics engineer you know electricity is like water in the way it flows. Meaning the bigger the pipe(wire) the more flow you get.(i'm sure you know thisbut....) Well if you have it coming in you have to get it out just the same. If you have a 3 in. Pipe bringing water in and a 1.5in draining it out whats gonna happen? It's gonna back up. If you use a 4 guage power and an 8 gauge ground you'll have more power coming in than going out. This will cause you amp to heat up and give long enough will burn iyour amp up and possibly start a fire in your car. I've seem it happen before more than once.
