HAve a Volvo HA-3141 2x40W amp to install 200 1988

in the wifemobile. She likes 4 speakers, and the CR-4123 head unit does fine, as to High Fidelity - nothing exotic needed.

Needs the amp to power rear speakers. Got in on eBay, under $30. The wires are all there, and I can maybe figure out what goes where, but if you already know what goes where, it would help me a bunch.

Here's what wires are there, and my guess as to where they go.


Fat black cord with DIN connector ------------------------ into head unit jack.

Heavy gauge black with insulated male spade connector ----------- into a ground?

Heavy gauge yellow with insulated male round connector ---------- into the head unit power on? or to a constant power and the "on" signal comes elsewhere.


Six place connector, five are used with light gauge wires.

Pair #1 -- Black and white/black stripe --- to one rear speaker??

Pair #2 -- Black and uellow/black stripe ---- to the other rear speaker??

Single wire ---- just plain black --- to ground on the head unit frame?? Maybe the "on" signal??

The unit came out of a 1989 780.

The question marks are my guesses. Any help will be appreciated!!


Thanks in advance,

Bob
