Why 8WG only? Why not 10 or 12AWG?
8AWG is thicker than 10 or 12AWG. It is not like the mmsq with more being more. 8AWG = 8.36mm2 according to an online converter. A 4-ch or 2-ch amp in this range will not pull so much current as to need a higher gauge cable.
I plan to use a ipod nano I got for free or a usb thumb drive only which is pocketable. I dont want any CD's litterring my car ... I will have to skip that but thanks for looking.
I dont want to wait indefinitely for a great 2nd hand deal. If I see that older Alpine unit that plays usb while I search for a new product nothing like it.
Here you go:
Alphine CDE 9881 with iPod Connection cable (KCE-422i))
It will not be tough to locate a 9881. They did sell in decent numbers back when they were launched. I think (not 100% sure) that a Nano will work with the full speed interface KCE-422i. Does the Nano have the usual 18-pin Apple connector?
