Hi guys! New member here! :hi:
Enjoy my 7 already for 7-8 months, but never had a chance to register here...

I got a question about subwoofers in 745. It seems that mine are "turned-off" or I just don't feel them AT ALL...as if my car doesn't have them....I tried that FAQ web site for E65 but didn't see anything about it. What can be the problem? BTW, I have Premium Sound Package.

Thanks for help!

p.s. Some pics...

Well Uhh From 02 and up all 7ers have 2 subwoofers. These could be the following reasons: Maybe there is some lose connection. Under entertainment go to tone and then to bass and turn it up. subwoofers may be popped or blown. But first check the tone thing.

Hope this helps, Let me know...

:( Bass is allllll they way UP...so...I dunno what to do

pwned, I don't how it is on BMWs, but when I listen music in Mom's Lexus GX470 and bass is at the highest point, mirror would shake, but my 7 is not like dat :tsk:

Same problem.... Seems after the last service last month the stereo quit working. Lexus= A ghetto stereo designed for clarity sacrficed for power.

P.S.- Good choice in colors :thumbup: Our Car-

It seems like the same problem that I had on my 2003 745i. The subwoofers just quit, and the whole system sounded flat. Even if you pumped up the bass with the eq and bass switch, it didn't really make the "thump" it used to have before. I took it in for service, and the tech notes stated that the "closed circuit current too high" and there was also a "battery disconnect" problem. Everything works fine now. Hope this helps.

the subs are either blown or not properly connected. I also have premium sound, and the two subs provide deep and rich bass. Get you bimmer to your service center and have them look into it.

Seems that way, too bad about the little bumper scratch. Whats all the options you got on your car?

Our options-
2002 BMW 745i Black/Black
*Premium Sound Package
*Luxury Seating Package
*19" Star-Spoke Wheels
*Convience Package
*Adaptive Ride Package
*Sunshade Package
*Xenons

Too bad 760 came out in 2003, after we bought ours, and concidering all our previous 7er's were V-12s. :( We'll probably get the new V-12 on the '08 7-Series.

Exactly the same, but mine is 2005 black/black and does not have adaptive ride package :)
I was looking at 760i too, but price is crazy + I don't need that much power. The only thing that I reaaaaaaly like ALCANTARA interior :)

Did I put the adaptive ride package? I must have not been paying attention sorry, I don't have it. Yeah I like the alcantara interior, our headliner has black marks on it where the grease monkies at the dealer rubbed their nasty hands on it, i'd like to kick them in the nuts. I like the 760i but i'd have to get the luxury seating package slapped in it custom because after driving around with those cooling seats on hot summer days I don't think i'd ever buy another car without them. Those A8L W12's are faster in the 0-60 run than the 760Li and, I could be wrong, the 760i too. Wheels on 760i are awesome.

760 is not a very good investment, they depreciate much faster, and V12 is not a great idea with today's gas prices from a resale value point of view.
I saw many 2003 760 cars in the $75,000 range.
The new 750 has a lot more power than the 745, and power wise it drives almost like the 760, I test drove one about a week ago.
So I would rather get a brand new 750Li than a used 2003-2004 760

Do you guys get any bass power from any of the speakers? If not then you could have a bad amp.

the rest of the speakers are restricted by a crossover, only the subs get fed the deeper signals....

Yep i was thinking Defective amp as well since its common for them to go out. When the subs are working you will have no problems shaking all the mirrors in the car trust me.

The logic 7 doesnt really shake your rear view mirror like alot of other cars i think they were looking for more clarity then bass power when they desighned it. At least mine anyway i dont have bass or logic set all the way.

I dont have logic but I do have a new amp and ask, the bass shakes the side views alittle.

Anyone fix their problem? What was wrong? Or do you just stop coming on here after its fixed lol.

For those of you that have the same problem, I promise I will come back after I get mine fixed and let you know the details.

it'll be the logic 7 amp ! get your system upgraded with aftermarket kit and save it from happening again !!

10-22-2009, 02:44 PM
can i simply get the amp replaced by an aftermarket one? it could also be the ASK...

bembo19
10-22-2009, 02:53 PM
not sure ! its not as straight forward as that but these cars are not as new to audio shops now so get them to price it up ! bet its still cheaper than the OEM amp !?

Try doing a MOST rest. If that don't work look up ask unit and Logic 7 in the search box. Tons of threads on them.

(Kinda why your not getting and productive replies)

your logic 7 amp is bad, try a most reset or disconnect the negative side of the battery for a couple of minutes.
