well my i got a free Alpine 3523 2channel amp from my buddy for free...its a REALLY old amp and i cannot find any information about it but if it WORKS im going to connect my rear 6x9's to it. BUT i have 1 problem i dont have the harness for the PWR REMOTE and GND connector.
anyone have any tips on how to make connectors ? (its a old amp i know but it was free

)
and theres a switch for FIXED and VARIABLE ...im not sure what that is .. maybe the cross over? but which one should i be using?

thanks in advance guys
