hifi audio

hey guys I just bought a g30 with base audio system... its definitely needs some attention, so my question is can I grab the front door speaker wires in the trunk on the driver side, and just run them hi level into a dsp, or is the signal modified by the oem amp/deck, and have to be detuned befor going into aftermarket amps??? my choices are a Dayton dsp, or the ms8 depending on the speakers signal, the Dayton will not flatten out any response, the ms-8 will flatten any signal out..
I wil have to run a pair of speaker wires into each front door for the tweeters as well...I did this on my f30 msport.. was pretty easy on that car.. I will assume its the same door plug..

Does your base system include amplifier/tweeters or not?

There seems to be some mixups from time to time because in some countries the "base" stereo is 676 hifi, when the real base setup is the business audio without amplifier and no tweeters. If you do have the base system without tweeters and amp, you must run new wiring for underseat woofers so the mid speakers and woofers are not connected together anymore.

I used these plugs when replacing my base system with Match UP 7BMW and Audison speakers:
The ones with looped wiring keeps the connection intact to door speakers and the other ones are plugged to subwoofers and you can run the new wiring from these to the new amplifier.


Base system does have some equalizations done to compensate the missing tweeters, so if you install tweeters & amp you must code headunit to hifi, either by adding 676 to VO or manually changing these lines via FDL coding:
Code:
AMPLIFIER_VARIANT external
AUDIO_SYSTEM hifi

Check this thread out, someone was just thinking of upgrading their amplifier with Match one, in the 2# post you can find a link to another topic which shows installation of Match UP 7BMW amp to X3 G01.

Hopefully it helps, i highly recommend replacing the hifi amp with Match UP. It's the best plug'n'play amp for hifi options and makes a world of difference.

ok gonna try the match first, see how it sounds. IF still not happy, replace the door mids and tweetes with AudioFrogand replace the oem underseat 6.5s with oem hk 8s, and last add a small 500 watt jl audio xd 300/1d sub amp and one dvc Audiofrog 12.
