my subwoofer under the passenger seat is blown i found this thread http://www.e90post.com/forums/showthread.php?t=1168879

idk how far he got but i think i have the same issue

i have hifi system i have to set the bass in the eq to -8 to be able to listen to music mid loud if i have it below 3-4 i cant really raise the volume or all the music sounds like complete shit.. i have a subwoofer in the trunk so i dont mind cutting off the sub under the seat just dont know how too. also not sure if its blown as it does still move but makes a rattle noise when too loud now. i was reading and allot of people have said the amp can be an issue to i was looking into the bimmertech amp as it makes the stock sound system sound much better

We know the Hi Fi system is weak
So adding a subwoofer to a weak system gets you = weak system plus
heavy bass.
The under seat positions carry the midbass and midrange frequencys
so getting rid of it will give you a serious hole in the frequency range.
The answer is to fix whats wrong in the first place.
That means upgrading the amp for the stock positions and a set of decent speakers for all the front locations.
the helix 82dsp marketed by Bimmertech and a few others is the current
favorite route to upgrading the Hi Fi system.
Read some of the thread on it.
