Need 2011 535i audio upgrade options!

Greetings!

Previously, I owned a 2011 535i. This had the s677a Logic 7 package. I was 100% happy with this system. It was pretty clear with decent lows . I also could connect via Bluetooth. After an accident, I picked up another 2011 535i. Ignorant at the time, I didn't realize that it did not have the same sound system.

It has the s676a Hi-fi system - and I hate it. It distorts as soon as I turn it up a bit, it's muddy and the lows are awful. Lately, I've been researching upgrade options. After perusing Bimmertech, is dropping almost $2500 for their Amp, woofers and speakers a good price? I've looked on here some and I see some upgrades that looked as of they began with the J/l 600/6 amplifier. Does anyone have any recommendations for me that would get decent results for less than the 2.5k with Bimmertech?

Ideally, I'd like to upgrade to an Amp with DSP, as my head unit just has the basic bass and treble controls with only phone Bluetooth connectivity. I'd like the Amp to power the car and perhaps change out the underseat woofers and door speakers with the ability to power a trunk subwoofer in the future. Any help or suggestions are greatly appreciated

I love your build. I may have missed it, but was everything purchases stateside? Looking to replicate it but I'm in Georgia, USA. What's the best place to buy the Gladen Alphas as well as the Matchup Amp? Also, was the box for the sub part of the kit or did you build it?

The Gladens I bought on ebay but they were here in the states. They Only had 1 set or else i would have to order them out of Germany so i got lucky on that.. The amp I bought from Italy as no USA seller had them unless you want to go with BIMMERTECH but there's is not a DSP.
