hi there! i wanted to ask information about my 2007 328i with idrive.. sorry i know this question been answered alot of times but i cant really understand or get what my looking for..

the thing is, i know i dont have fiber optics wiring, but when i went to the dealer i ask about my audio system the guy said i have hifi audio with no dsp or nonlogic 7 but i have fiber optics wiring cuz i have idrive..

FYI

http://www.e90post.com/forums/showthread.php?t=365866

There is no Fiiber optics between your Head Unit and Amp .(if you have Hi Fi)
There is fiberoptics between bluetooth , SOS, CD Changer, ipod if you
have it on something called the Most Bus(this exists idrive or standard) . If you go through the
links in the above link you will have a pretty good idea of whats
in the system , its specs and what you can do with it.

There are specs in the pdf and tis files that make things pretty clear.

If you want to save yourself a lot of time I suggest you get in touch
with VP Electricity at Musicar of Portland he has kits of known configuration
that work with all the shims , machining and stuff you need. Also
he can give great technial support and direct you to a shop in your
area that can do the work and not a hack job if you can't self install.

Thanks alot for quick reply! Wow! This is the best forum!

I'm just wondering, let say you have two amps, one for your subs and the other one for your speakers. Does it advisable to add a capacitor to your system? Does it require one?..

Thanks alot in advance!!

The iDrive itself is no reason to have fiber optics, however if there is Assist/Bluetooth, USB, CD Changer, Sirius or HD Radio in your car then it will have fiber optics.

Regardless of having iDrive or not, fiber optics or not, adding a sub just involves finding the woofer wires in your car and tapping them as inputs to your sub amp. A LOC will be required.

If you install it correctly, ie correct gauge wire, proper ground etc, ^no.

I have an M500 and a JL 500/1....it's fine without a cap but I have one wired in anyway because I had one laying around.

Thanks alot! I really appreciate every reply..this is the best!!

Technic.. I have question about LOC, I found a LOC comes with sound processor, ... Here's a link...

http://www.sonicelectronix.com/item_18560_Hifonics-Maxxsonics-MX-1.html

.. It has a feature that turn off/on the aftermarket amp by means of signal from the sub wire, something like that.. Does this product is good that you can recommend to use for LOC? And the feature that turn off/on the aftermarket amp I don't have to buy a relay to protect the HU?... Or the best choice is having a relay and simple LOC that is compatible?


Thanks alot again in advance! Appreciate everything!
