The improvement from the Alpine kit are still limited compared to just exchanging the speakers with a Match or MB Quart set.
A set cost around 350

BUT - compared to just adding a DSP amp to the OEM speakers and trimming the sound, then the expirienced gain in sound is limited.

Finally, it has nothing to with being an audio head - it is just expirience talking...

Alpine Kit 350
L7 Subs 100

Coding TBD

450 sounds good to me for such a major improvement.

Hi,

Wish i could buy the 4ch amp and bimmertech's accessories separately
-> no need, you anyway can connect the 4ch amp with the supplied cable + a BMW specific adaptor behind the radio = plug & play

in principle you need this:

PP41DSP BMW 1.0 Edition amplifier
PP-EC-40 4 metre cable,
PP-AC13A BMW P&P

rest is driving and enjoying time...

Btw bimmertech claims they reprogrammed and customised audiotec's 8ch amp especially for BMW and it comes with plug&play harness and a bracket which costs me extra $200
Wish i could buy the 4ch amp and bimmertech's accessories separately but that harness must be designed for the 8ch amp
Any idea?
