using to run from my Battery to my distribution block.. I have a total of 550 Watt RMS between two amps. I was going to get 4 Guage is that over kill??

Also, where can I get that from at a Cheap price?? I need like 16ft.. I keep seeing $2.50 per ft..

 

IMO, you can never overkill Power distribution. I'll check on some prices and let you know....

 

You could get that at Crutchfield or Parts express but the shipping charges will probably bring it up higher than the local shop prices. Find a place that isn't a big chain and get a salesman who isn't the newest person in the store. They should be able to sell it for less. I normally try to talk to the owner or manager when there aren't a lot of other customers around. I think they are more likely to work a deal then especially if they think you may be in the market for more equipment.

 

 

I had this question also. . . What guage wire does everyone run in their car? My installers ran 8 Guage wire for each of my amps. and I thought they knew what they were doing. The other day I went to another place that sold PPI and the were concerned about the 8 Guage wire being used thinking that PPI would probablt recommend 4 Guage for the length the wire was run. Should I be concerned about this?

 

But only because each amp, has to be wired up like 2 amps. There are 2 pos. connections and 2 ground for each amp.

 

Okay guys I have tried to recreate the wire chart from the MECP study guide:

Iasca’s recommended minimum wire gauge size*

Wire Length
Total Amperage Up to 4 to 7 to 10 to 13 to 16 to 19 to
Draw of System 4 ft 7 ft 10 ft 13 ft 16 ft 19 ft 22 ft
0-20 14 12 12 10 10 8 8
20-35 12 10 8 8 6 6 6
35-50 10 8 8 6 4 4 4
50-65 8 8 6 4 4 4 4
65-85 6 6 4 4 2 2 2
85-105 6 6 4 2 2 2 2
105-125 4 4 4 2 0 0 0
125-150 2 2 2 0 0 0 0

Dang. I guess Excel files can't be copied to the post. But I think you can make it out.

 

In your case, since you have 550 watts I would definetely recommend 4 guage power wire. For myself, I am running 8 guage wire because I only have a 225 watt amp and a 125 watt sub.
