+1...Hi - For what it's worth, here is a very, very easy fix-> Run your iPod /mp3 player directly off of your amp. My car is a '86 and there was no auxiliary out-put on the factory Blaupunkt and the radio shop wanted too much to install one. What I did was very simple, but you lose your radio but it
is very easy to reconnect if you choose to.
1. I left the radio's power from the amp on so that when I turn the radio on (with the ignition on) it powers the amp.
2. I then unplugged my radio input RCA cable from the amp...
3. I ran a new 6' iPod gorilla cable from this input into the car via the wiring harness hole on the passenger side firewall; under the carpet up to my center console.
You now just have to plug in your iPod/mp3 player into the new cable; turn on the radio and turn up the sound!...The only drawback is that I have to adjust the volume from the iPod which hasn't been a problem.
My amp was installed right tight against the right inner fender well and to reconnect the radio it's just a matter of unplugging and replugging the RCA jack.If you use your radio a lot then this is of course not the way to go.
.But if you want 'instant' sound the above only takes a few minutes... Just the time to run the new cable to the console.
Cheers!
ps- If you go this route, have your iPod plugged in and your radio on
before you start the car....If not, when you do turn the radio on you will get a loud 'pop' from the amp. It doesn't damage anything but your ears
