  1. You have to understand that weight means nothing. The actual purity of the copper and jacket are very critical. Look at this chart. http://www.armstrongssupply.com/wire_chart.htm If the wire isn't UL listed I don't car the weight size of circular mill. UL listed wire meets the standards on premium insulation and dissipation properties and true OFC copper. Just cuz it's says ofc does mean it's not Chinese recycled copper. Lol Basically weight and size don't mean much what you want to know is resistance near the wire therminal limit. Like measuring power compression on a voice coil for example.
  2. I'm a certified technician in plc and electrical systems. I've spent over 20 years building testing installing and designing electrical power distribution and control systems from floating offshore rings to power plants. I want to start with a simple topic. That's debated and I'm just down-right tired of the misconceptions. STRAND COUNT- Higher strand means lower resistance in the same gauge and results in higher ampacity(how much current can flow for a given voltage drop). This is completely false. Soil wire of the same circular mill vs high strand count will have both less resistance and higher ampacity. Think about this. Why would 200,000$ Industrial load centers waste time with solid busbar and not just use heavy jacketed high strand wire? 3 apparent reasons. Termination and ampacity heat dissipation. Termination meaning you get the best contact area and you can get consistent torqued connections. This is VERY important in long term connections where thermal expansion occurs. 2 solid busbars have considerably higher ampacity. The election flow flows much better in solids. 3 dissipation, the bars are exposed to air and any cooling installed rids the heat substantially faster. Strand count is only advantage is flexibility. If you have a 1/0 wire that has a 200 strand count(thhn) it's circular mill is 325 to meet the nec standard of 1/0 wire. Welding wire has near 3000 strands and in order to meet the same standard needs to be nearly 400 circular mill. Same for car audio wire. It needs to be neat 450 circular mill. So knowing that now you understand why welding cable 2/0 fits into car audio 1/0. Fyl weling cable 2/0 will carry about 40 mores amps over the same distance with the same voltage drop. Gonna keep this short and sweet. Fusing is for safety. It is not over current protection. You fuse to the maximum ampacity of your wire and you wire for 125% of you loads ampacity. Do this and you will never have issues. Voltage drop is defined buy the wires resistance and the current in the circuit. It's that easy. Also in a DC circuit the length of both the ground and power wire are factored in. 4ft power and 3 foot ground is 7ft.
  3. you have plenty space what are you looking to accomplish? i could suggest something but it might not be what you like. the best advice i can offer is to get phasing close to coupling around a centered frequency as you can. be more specific as to what your trying to accomplish.
  4. without know the drivers parameters you might as well build a 10 cubed box for 1 and work your way down.. or order this lil fucker and you can have an idea of what you need..http://www.parts-express.com/dayton-audio-dats-v2-computer-based-audio-component-test-system--390-806 for 100 bucks you cant really go wrong
  5. what are your maximum dimensions? what is it going it? how much power you have and what type of response are you looking for?
