bought this off ebay for just under a tenner and i thought if all else fails it will look pretty cool whatever happens

Its a retro EQ and kinda mini amp i guess
here is a pic of the wiring

The power and earth are pretty clear.
now there is no low level rca inputs only wires
the grey and brown wires have striped earths so i presume that they are the speaker outputs
the system has a fader on it and left to right levels so must have 4 outputs. there is also a green pair and purple pair of wires which could also be outputs or inputs.
there is a red, white, yellow and blue wire spare, these i think are different inputs.
any help would be great. even if you have seen this in a car before
there is no model number on the unit anywhere
