: L7 bass ?

06-24-2012, 06:51 PM
I just bought my first bimmer- 2006 750I with L7 sound . Over all the sound is crystal clear and impressive. I can hear the bass but I don't feel it. In my Tahoe I can feel the punch of each bass note. In the 750 I can't feel the kick. I excpected more punch with the subs under each seat. Just hoping my amp isn't dying . Any thoughts? Is this the norm.

I've messed with the settings but wish the subs had their own setting like in a lot of vehicles so I could feel out the right level for them . Anyone willing to post a pic of their eq and other settings? I listen mostly to rock but I want to feel the kick of the drum.

That is pretty heavy on the bass buddy! :rofl:

After you have set your EQ, although I think Rookie2008 has his Bass a lil too high, I would have the Treble All the way up and Bass half way.
There is also another setting for the Logic7 which can be raised as well.

Too be honest there is hardly any bass:(. The reason is my subs are not working so the only bass I'm getting at the moment is from the rest of the speakers:mad:. I know once I fixed the subs it will be too much bass:).

I hope im not the one to tell u this but i think you may have blown subs or the L7 amp or ask.
When i first got my 750 six months ago, it had to much BASS. then i would notice a slight cracking noise when i would get in and out of my car when the car was radio was shut down. Now when i hear my music, i hear the Bass hit but i dont feel it. The other speakers are fine. I just havent had time to get to a shop to verify, but from looking at all the other forms, it seems as there is a faulty L7 or ask amp

Is there any way to isolate the subs so only they are firing. Or can you unhook them from the amp so I can hear if there is a difference. I'm interested in adding a sub hox to the trunk and I have heard someone makes a harness to do so but can't find it , any one have any info or a link

Well I thought that was the reason my subs were not playing. So I had my L7 repair a year ago by a member on here. Needless to say when I got it back the same thing no bass. What I did was had to turn the bass up on my mids an highs to get a clear sounds with a little bass. Another member on here added 2 small 10" boxes in my truck to give me bass. I needed up turning the after market amp all the way down but the quality just wasn't the same. I still needed bass. So Last night I bought some replacement L7 subs so I will be changing my L7 settings. Can anyone post some pic of there settings please.

Please let me know the end result
I would love to just purchase some aftermarket Subs to resolve the problem
I dont want to really mess with the amp

06-26-2012, 09:25 AM
No actually the are OEM subs I bought last night. I just need to figure out how to get my seats out:mad:

06-26-2012, 09:39 AM
either way this will let me know if its the amp of the speakers
good luck:thumbup:

06-26-2012, 09:42 AM
LOL Thanks yea luck is what I am going to need I will let you know.

06-26-2012, 05:44 PM
Well my problem was just my eq settings, I set it close to the pic that was posted and I can now feel a pretty good kick from the bass. Still interested in knowing if there is an adapter to add an amp and sub in the trunk daisy chained off the L7 amp?

Hey Rookie,
im having the same problem...my subs arent working but my other speakers are. i replaced the L7 amp, that didnt fix it. i dont think the ask unit is the problem...please let me know if the replacing the subs underneath the seat fixes the problem...i dont know what else to do. thanks

06-26-2012, 09:56 PM
No problem

07-02-2012, 08:15 AM
I feel like an idiot

I never checked my balance on my Idrive and when i did, i noticed that there was no mid's or Bass coming out of the Left side. I mean all you heard was just some highs in the front
nothing in the back what so ever
I know it has to be the damn Logic 7 Amp or ASK:mad:

07-02-2012, 08:57 AM
I haven't replace the subs yet. My front passenger set will not go forward only one side of the passenger seat wants to slide forward so I haven't even bother with it yet. Any ways It's seems like it's going to be a pain to remove the seats.

07-02-2012, 09:43 AM
My mechanic had some trick that makes taking out the seats easier than the BMW instructions. I think you just remove most of that plastic covering the edges of the bottom of the seat and there's like 4 bolts to remove and the track and everything just lifts out!

07-02-2012, 09:45 AM
I seen the 4 bolts on the driver side your talking about but I haven't seen them on the passenger side.. These 4 bolts in the pic right? http://tis.spaghetticoder.org/s/view.pl?1/07/20/27

07-15-2012, 04:16 PM
hey Rookie,
where you able to replace the subs underneath the seats? did that fix the problem? thanks

07-15-2012, 04:18 PM
Yes actually I replaced the drive I'm having trouble at the moment on the passenger side at the moment.

07-15-2012, 04:22 PM
cool, so the problem was a bad sub? did you get aftermarket subs or oem replacements? I think we both have the same problem (bad subs)...not sure if i should buy the same subs or get an aftermarket sub, that might sound better. what do you suggest? thanks

07-15-2012, 04:25 PM
2 problems actually. My bad subs killed the sub out put on the amp. I had to replace with the new ones I got from a member an get my amp fixed. I just got my amp back yesterday. Now my bass is kicking. The only problem is my passenger seat will not go forward or backwards so I cant replace the sub. I unplugged it so it will not burn out my amp again.

07-15-2012, 04:40 PM
thanks, im looking to get oem subs...im looking at a listing on ebay right now...http://www.ebay.com/itm/02-07-BMW-745LI-745I-750LI-750I-OEM-SUB-WOOFERS-/221050936574?pt=Car_Audio_Video&hash=item3377a99cfe&vxp=mtr#ht_500wt_1282
