not enough power
So I just get to start driving my car yesterday because I've been doing some work on it. My problem is that when I drive around town and my electric fan turns on it takes all the power. So then my cd player goes quiet and fuzzy.
I take it my alternator can't give enough power to power both.
Anyone have any solutions.

Get a 2nd gen alternator.
Remember, the stock stereo system was designed to use no more than 30 (?) amps or so. Most modern systems try and put that in ONE channel...

Definitely test your alternator.
Might also be a good idea to check your electrical fan ground, run some additional grounds and a parallel output from your alternator to your +ve battery terminal.
(The latter worked really well for me).
If it turns out to be your alternator you can use a fc alternator (Series 4 ~ 60A Series 5 ~ 80A, FD ~100A) if you like.

Check the voltage drop across the battery ground cable. I've fixed a whole bunch of electric problems on cars by replacing the ground cable. If you wanna get fancy use arc welding cable from a welding shop - guaranteed to be lowest resistance. A surprising small drop on the ground (1 to 1.5 volts) causes all kinds of problems, like even the starter mightnot turnover.
