Is it worth switching from aluminum to copper? I heard somewhere that aluminum is like half as conductive as copper. Is that true? I've been looking around lately but can't find any 2 gauge copper which is the most my amp will take.
you can always use 1/0 and then use wire reducers to make it fit your ampIs it worth switching from aluminum to copper? I heard somewhere that aluminum is like half as conductive as copper.

You heard wrong. Theres not that^ much difference in the conductivity, copper has better heat characteristics. Aluminum wire will swell and contract more than copper when going through cycles. Usually you can just go up one size with aluminum wire to achieve the same amperage rating as copper.Is it worth switching from aluminum to copper?

i think he saw the other thread where it says 1/0 copper = 2/0 aluminumYou heard wrong. Theres not that^ much difference in the conductivity, copper has better heat characteristics.

the cheaper knu is copper clad aluminumwhat wire do you have? the only aluminum wire i can think of is stiff as fawk and is used underground/in houses. you may have tinned OFC (which looks a lot like aluminum) but i really doubt you have aluminum wire unless you were fuckin up.

it's just a property of the metal...even the 1/0 CCA Knu wire can handle up to 250A IIRC.
but he has 2ga RF wire...
how does aluminum oxidize?
i thought it was crazy hard to oxidize aluminum?? //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gifAluminium is remarkable for its ability to resist corrosion (due to the phenomenon of passivation) and its low density.....Corrosion resistance can be excellent due to a thin surface layer of aluminium oxide that forms when the metal is exposed to air, effectively preventing further oxidation.
