I am not totally happy with the stock system in my 545i. It is "decent" but I would expect better for a $63k car. The factory system in the '05 up Mustangs is far superior for example. I am thinking about upgrading all the speakers but would like to do it on a reasonable budget. I am not looking for ground shaking bass. I was thinking new components maybe in the front/rear, center channel, and some new 8" subs under the seats. I am very capable with wiring and building baffle plates etc. as I have done a decent amount of systems. I am looking for some suggestions on what works well in these cars and any tips/tricks! Thanks!

Welcome to BMW Audio, they could never get it right before 2010 lol. what system do you have 10 speaker or Logic 7 ?

i changed out my speakers and added a sub. What was different with the BMW over the cars i had had in the past was the fact the component speakers were a tweater and a 4 inch speaker, rather than the typical 6 1/2 inch speaker. This gave me less options. I didnt go the cheaper route so i got 4 sets of Focal components that ran $300 a speaker. so $1,200 just for the speakers. all and all the system coast me $4,000. Just wanted to make you aware of the 4inch if you didnt know already

Standard 10 speaker setup. I definitely am not spending a ton, I did notice it is a 4".

I will be soon taking out all my audio from the car and turning that back to stock. I have earthquake subs and a fosgate driving them.

For starters I installed a JBL MS-8. Even with the stock speakers it sounds a lot better and actually improved the bass.

From there you can upgrade the speakers, install subs, sub amps, etc...The MS-8 would be the initial sound processing "brain".

I just added a sub in the trunk with a small amp. I did not cut through what would be the ski port and the bass in the car is plenty for me. In fact, I can't turn it all they way up. No other speaker change and I am more than pleased with it. There are several DIY's here for the amp install if you need it.

I have also looked into upgrading my speakers for my 2004 525i. I think most people would suggest going with a stronger amp and also upgrading the subwoofers underneath the seat. I've read that its good to use earthquake sws 8 for the subwoofers and a blaupunkt amp.

The route I'm going is Hertz Mille 3 way set up audioson 5 channel amp jl audio tw5 flat sub and audison bit ten d. Another option for our cars is the jehnert speakers made for bmws
