I was given an amplifier today for free. It seems to work but i need to know how to connect it up. I was thinking about putting it under the drivers seat on some sort of bracket. I can figure out how to do that but i may need some info on how to wire the damn thing. It is a MOTORPRO AG 7190 60 Watts x 2 (not much i know but it was free). I am gonna run it off the standard EA head unit for a month or so til i get a CD Player. There is space for 4 speakers on the amp (8 wires which is all good), a power lead, a car chassis ground wire????, a normal ground wire?????, and 4 other grey wires that connect into the head unit ( my head unit only has 2 channels though). Will this work and do i only connect 2 of the grey wires or all four and just double them up? Also I am not too sure what the ground leads do or where they go so any help on that would be good also.
