There are many resources available online to help aid you in your Volvo speaker wiring needs.Whether your an expert Volvo mobile electronics installer, Volvo fanatic, or a novice Volvo enthusiast with a Volvo, a Volvo car speaker wiring diagram can save yourself a lot of time. Automotive wiring in Volvo vehicles are becoming increasing more difficult to identify due to the installation of more advanced factory oem electronics.
One of the most time consuming tasks with installing an after market car stereo, car radio, satellite radio, xm radio, car speakers, tweeters, car subwoofer, crossovers, audio equalizer, car amplifier, mobile amp, car amplifier, mp3 player, ipod or any car audio electronics is identifying the correct color car audio wires for your Volvo.

I switched to an aftermarket car stereo from the stock system originally installed. I purchased the appropriate wire harness & everything is wired properly… Something is definitely wrong though because:
– Only one speaker plays (front-right).
– The volume is effectively an on-off switch (doesn’t adjust the volume).
– When I play CDs, it’s especially noisy (sounds like some radio interference).
There’s a spare orange wire on the harness that doesn’t have a partner on my stereo.The Stereo is a Blaupunc. I’ve checked the wiring several times. I checked the fuses, but now the lights are blinking on my Climate Control system.

Have you put the original unit back in to test that the weird symptoms only exist with this new Blaupunkt. If this is the case, then it does sound like you are unlucky with a faulty new radio.

Here’s a wiring diagram: http://au.geocities.com/ozbrick850/Radi … ctors.html
Keep in mind that the dash and front door speakers are wired directly to the harness, but the rear deck and rear door speakers are wired in parallel to each other and are 8ohms each.
