Can we get a post that has nothing but the facts, like:

1. How do you change it, and where to get info.
2. How much, and what are people using.
3. Where can you get it done if you dont want to do it yourself.

It would be nice to get more links to tutorials like the ones Mogi has provided in a previous post.

Then use this link for the wire harness and amp install.

I am sick of my head unit, and need to change it. I am sure i am not alone in this issue.

I would love to get some facts also on my 325e E30 on what you need to replace the head unit (wire harness, etc)

1. take of your stock deck
2. buy a wiring harness for you car(any audio store)
3. plug in that harness to the wires that in you car
4. then you will end up with the wires.
5. connect those wires to the deck you got.(read your deck manual)
that's it
deck can be changed in 10-15mins

to the best of my knowledge theres no harness for an 85 325 so just hardwire it..

Exactly, I was talking to my friend about it and he says to buy 25' of wire (copper, low gauge?) And run that from my speakers to my head unit? Does that sound right?

The thing is, I don't know how. What the hell is the difference between ground, and whatever the other one is?

What about power? Would I need to run new wires for that?
Sorry if I'm a bit cranky, I'm tired and sleepy.


Thanks!!!!

Oh yeah, I just bought the Kenwood KDC-319.

Yeah, it very easy to change a deck, don't take it to a place to do it for you. As Sickfinga said before, if there isn't a wiring harness for your car, then handwire it, the wires should be colour cordinated. Just to let you know, if you are changing the headunit bcause you want a CD player it is a good reason. If you are changing it to get way better sound, you are going to be disappointed. When a deck says they are runnnin say 45X4W, that is at peak which the deck will never get. Nominal or RMS power it is running about 22X4W. For looks and getting a CD player in your car, it is a good reason to change. Also if you have subs, get a deck with sub controls and stuff, so you can adjust your sub from the headunit which makes it a lot easier. I had a Pioneer DEH-7300 CD/AM/FM and it is one of the top of the lines and it was fantastic.

I did not change my speaker wire, I would have done my deck myself but It came with a free install, but I had read over the instructions on how to do it, its just finding the color code for your car and wiring it up with the corresponding wires on the deck.

323is, An aftermarket deck alone is an Improvment over 85 technology, also if u add speakers to that (like I did) it is a greater improvment, I am going to add an amp later then It will be great

ya 45x4 i bullshit, when you readthe spec sheet of my deck the RMS is 17

And It was me who said hardwire it :P

Also, what do you mean to hardwire it?
