What Size wires do I need to hook up my subs?

Question

I just got two 10' Rockford Fosgate in a sealed box with a 650 watt amp. and Someone offered me some new wires that were a 10 Gauge.

I dont know if i should take the 10 gauge or buy another size.

I know my buddy has two 12 R's and 0 Gauge wires.

but he has 1000 watts.

what are the effects of it being too small or too big?

and whats the perfect size?

Answer 1

Your friend does NOT have size 0, because there is NO size 0. It goes from # 2 to a 1/0 then 2/0 ...

#10 wire is good for your amp.

you could use a stranded #8, but that is huge, and it will not hide or form easily.

You could use #12 wires.

Effects of being too small, is that it would cause heating in wires, which would radiate to amp and speakers.

Answer 2

go with 6 or 8 gauge subwoofer wire. but 10 will work

Answer 3

For these subwoofers that are good in quality, I would suggest taking an 8 guage wire because that puts out more power at once than 10 guage. Your buddy probably has 0 guage because he wants more bass to hit at once, and isn't an everyday user. If he is then his sub might blow in a year so let him know. To power the 10's you might want to get a distribution block that sends the power from the battery which probably is 4 guage to switch from that big to going to 8 or 10 guage. In my opinion the 8 guage choice would be better, and its just nickles and dimes that you would really need, like mostly a dollar a foot of that stuff.

If you have too big of guage wire then it will probably blow the amp or subs because it runs too much power for the amp to take. Too small of guage wire would cause your amp to not put enough power to the subs, and the sound level wouldn't be as high as you could have it. Go to an expert and get a free opinion from them.
