its not necessary to have stringer wire ,
go get bulk wire
4 gauge or 2 gauge will be most havior
U cannot justify that quality is changed
u can make ur self satify that using branded wire making ur sound quality better ,
All matter is resistance in wire
Make ur wire length according to ur system , excess length of wire increases in resistance
cause Resistance is directly proportional to Length
as well as resistance is inversely proportional to Area "lower Gauge wire"
donot get fool by this
Most importantly about wiring, make sure it isnt cheapy wire. too many times have i seen guys buy "4 gauge" wire that IS technically 4 gauge, but its not ALL wire. its like 8 guage wire wrapped with 4 guage shielding.. or 8 gauge wire, surrounded by plastic filler.. calling it 4 gauge.. plastic doesnt conduct.. make sure you have great quality wire.
