Upgrading base stereo in 07 E92

I just purchased a 328i E92 and of course it has every option except logic 7 and I'm wondering what is the best way to go bout upgrading it. I know nothing about car audio and am looking to spend around $1k

You will have a hard time meeting the 1k number

But you can do something nice for about 1 to 1.5k if you can self install.

If you want to save your self a lot of anguish and hair pulling
get a kit from these guys.

http://www.musicarnw.com/page-2/

It includes everything you need and is pre wired and setup.

the fyi thread below

Since you are in Florida you might also want to get in touch with Technic
who lives in Fort Lauderdale I believe.(he is and East Coast expert and makes
the best stereo adapter harness for these he is also good at low cost recommendations)
You do not want to go to a common stereo shop with these or even good ones
that don't understand them.

BSW kit $510
JL Audio XD600/6 $370
Technics harness $75 ( I think)
Total 955
Add some wiring for power for amp, and some rcas etc
And you are around your $1000 budget

True
But the under seats sound a little better with an aftermarket amp
So it depends how much bass he wants

But won't and aftermarket amp toast those OEM's

But won't and aftermarket amp toast those OEM's speakers
For the xd600/6

If you do the numbers and since the OEM's are 2 ohm you are delivering
probably 5 times the power of the existing amp into cheap speakers.
the math on this says you are about 100 watts rms on speakers that were running on maybe 20 rms for the under seats and around 15 rms for the door if even that.

I wouldn't have suggested unless I had tested it
I was powering my oem HIFI subs with about 120w rms for awhile
Obviously then gain wasn't cranked up
But they were fine

Gee, kmarei, remind me to get you something for Christmas.

OP, we have full plug-and-play bolt-on upgrades that replace your front components, your underseat woofers, add an amp, and you don't have to cut a single wire in your car, and it all integrates with the stock wiring and head unit Shoot us an email off of our website and we will send you lots and lots of info on what we offer. Our Level One kits are in the price range you've stated.

that's alright
i wasn't expecting you to bless this upgrade
i don't believe you have ever commented positively on any upgrade that wasn't sold by your company

just a small footnote
i don't sell any of the items i suggest, nor am i in this field.
