 Posted: Sat Mar 11, 2006 10:53 pm Post subject: Headlight actuator and radio replacement |
 |
|
I have an 89 coupe and have a couple of questions.
Recently the passenger side headlight actuator has started to behave
strangely. When raising the light it stops about half way up then either
continues to open fully or stays where it is - half way up. This is
intermittent and usually goes away when I retry it a couple of times. Anyone
have any suggestions or do I need a new actuator?
I'm going to replace the Bose radio/cassette with a Blaupunkt radio/CD
player - the cassette drive stopped working a while ago. The Bose has 6
speakers and I believe each speaker has it's own built-in amplifier. The
Blaupunkt supports 4 speakers without amplifiers. Am I right thinking that:
1) I have to bypass the existing Bose amplifiers and connect the existing
speakers direct to the speaker wire from the Blaupunkt radio;
2) I can't drive 6 speakers from a 4 speaker radio
3) It's probably best to connect the new radio to the speakers in the rear
and the door for ease of access to bypass the amplifiers in the speakers -
or - is there an easy way to get at the speakers on the top of the dash
Thanks all,
Tony

Probably, but not necessarily. Just make sure the stereo you get has both Amplifier out (at least 50 watts/channel) AND line level outputs. If the setup is anything like on the C5, the front door speakers are power with amplifiers internal to the speaker module, but the rears are powered off the head unit. So, when replacing the deck only, you'd need hybrd output.

Depends on what kind of speakers (tweets, woofers, etc). If you wire two speakers in parallel, and ones a woofer and the other is a tweeter, you might be able to do it. Depends on the impedance of the speakers and the impedance capabilities of the amp driving it. Might need to add a passive crossover. Try it and see. Watch for relative volume levels, distortion, and clarity when connecting two compared with one.

There's probably going to be a big-old fat connector plugging into the back of the factory stereo containing all of the various wires to the speakers, power, ground, and what not. You should easily be able to find an after market mating connector on the web or where ever, that will plug into that connector and give you pigtails that you can wire up to an after market head unit.

Also, here's a little website I did on my C5 stereo upgrade. Might be helpful with your C4 install.
