But I promise this one will be quick...
I FINALLY got around to tackling a project I sorta started 4 years ago - building an Alpine-to-Jensen adapter to install my VM 9512 from my Dodge Stratus that I just sold.
Using my Viper shop service manuals and this diagram:
...I built my own harness. I used a factory Alpine plug that I removed from a defunct Alpine unit I bought off of Ebay, and an 8-pin female DIN adapter with pins.
From the diagram above, I wired the POSITIVE's of each speaker as labeled - pin 7 rear left, pin 5 rear right, pin 3 front left, pin 1 front right. To pin 6 I wired both rear grounds, and to pin 2, both front grounds. Pin 4 got the remote wire. Pin 8 - labeled "Ground" - I simply connected to battery ground - or the "GND" of the factory plug pictured on the left side of the above image. Basically, battery ground.
Was this a mistake? Everything WORKS - I get sound and if I turn up the volume, it sounds pretty good. But when I turn the volume very low, I get a high-pitched whine/buzz, and this is with the car in accessory mode - not running.
I'm wondering if I should have run all four speaker grounds to pin 8, thus leaving pins 6 and 2 empty.
The other option is that I didn't use the pre-outs, so I might simply have too hot of a signal coming from the Jensen, but I'm not getting any distortion (at least until the speakers start to buzz - I really should replace them at some point...)
I really don't have money to mess with new amps or speakers, nor the time to gut the car and run all new wires. We have a baby on the way and I'm working two jobs right now... Just trying to get this Jensen to work.
Any advice on my wiring is appreciated. Thanks so much.
