Question Speakers for 2006 323i

Hi Guys,

I have a 2006 323i, and I am looking for replacing the midrange speakers. I did some research, and thinking about Alpine SPS-410. However, I just want to make sure before I place the order.

1. Will SPS-410 fit 100% in 2006 323i? Is it a simple install? Any additional wires or screws needed?

2. I will replace 4 midranges, 2 in the doors, and 2 at back. Do I need to add an amp? If so, any suggestions?

I have never done the speakers before, and I think I can do it myself. Please, any suggestion is helpful.

Thanks.

There is a list of speakers in the speaker portion of the above thread.
Before you start changing things you need to figure out which of the
three common systems you have . Also a coupe will require thinner speakers
than a 4 door or wagon.

Hi ctuna, thanks so much.

I am 100% sure that I have the base / stereo. Also, I have gone through the posts you provided. It's an eye opener. Based on that, I will just start with replacing the speakers. Not adding an amp, not add tweeters. If only the speakers, do I need to recode the HU to HiFi? or adding a processor?

Speakers won't get you very far

Speakers won't get you very far
It may even sound worse as aftermarket speakers require more
power that the head unit alone just doesn't have.
You only recode if you are putting in an amp as it lowers the output
of the head unit to 5 volts and takes the eq out of the signal that is suppose to
compensate for no tweeters.

OK. I spent a couple of hours reading / searching the threads, but could not find 1 / 2 posts with the steps of recode. (i think there must be 1, but cannot find it). How difficult is it?

Seems the processor is very expensive, so, i think recoding is the only option?

Just did some further, I can use a cleansweep? so, it will be like:

HU -> Cleansweep -> AMP -> speaker?

If you are near a large city

If you are near a large city you may be able to find
a coder or an Indy with Autologic than can recode for you.
Its a cleaner way to to if you can get it done.
Then you would need a Technic Harness and speakers of your choice
I would suggest the JL 600/6 as the no trouble best amp replacement .
The links below describe the coding process.
Note both the process for the idrive and pro radio are in these threads
and they are different in that the stock radio use the rad file or some variation whereas
the idrive setup uses two or three different files that are written to the CCC.
