running new speaker wire?

[Chriskbmx]

so i just bought my 1987 bmw 325e and i am having some issues with the radio. when i bought it had no speakers, no headunit and there was no wiring from the factor, but wiring that went to all 4 speaker locations. my question is if i take the individual speaker wire and just wire it into the aftermarket radio harness? like poisitive left front from the speaker to the positive left on the harness? and i don't know what color the power and ground wire should be? can any one help?

see i looked through there and all i saw was about using the old wire that was there, when it is not there at all! i promise you it was all removed lol anychance you can point me to a page?

Dunno if this will help but I recently stripped out my interior to run new wires through my car cause I added an amp and sub and didn't have the premium system previously. I left the 6 important wires though which can all be found behind the glovebox (assuming your's car is similar to mine LHD vs RHD). Are these what you are looking for?

Cheers,

Yeah, just run new wire, try and keep it on the left side of the car

i did run wires on the left side of car. and i hooked all the positive and negatives to the speaker. but what do i do about a main ground and power?

also what is the difference between unswitched 12v and acc 12v?

unswitched 12v is hot all the time no matter if the ignition is on or off. acc 12v is switched, It's only hot when the ignition is on.

I don't know enough about this stuff to tell you where to get power. Sorry I can't be of more help.

i actually figured it out. ran my switched hot to the ignition switch at run and to battery power. now i have a functioning radio!
