[QUOTE="Jepalan, post: 8180828, member: 655519"] I always try to use manufacturer's recommended sizes, but you can calculate minimum wire sizes using this tool: [URL="http://www.bcae1.com/images/swfs/systemdesignassistant2.swf"]http://www.bcae1.com/images/swfs/systemdesignassistant2.swf[/URL] Use the white entry boxes and set wire length to 17ft and amp power to 500w rms each (conservative) and it comes up with: 2awg to distro block and 6awg to each amp. (set two of the amps to 0 in the tool) Assuming you don't run amps to max, set amps to 300w and it gives one 4awg to distro-block and 8awg to the amps. At least that gives you some confidence in ranges. As you can see the manufacturer recommendations are pretty conservative (esp the dual 4 awg connects on the GT amp). Tool assumes true gauge copper wire - nothing fancy [/QUOTE]
