u2cpooh Posted February 2, 2009 Report Share Posted February 2, 2009 I was told that getting a new Logic 7 amp for my '06 750Li would cost $1800. I would like to know if I can get an aftermarket amp and use the stock speakers. Basically, substituting aftermarket amp for the Logic 7. If this can be done, what kind of amp should it be and where do I get the signal for the subs? thomas Link to comment Share on other sites More sharing options...
gizze Posted February 2, 2009 Report Share Posted February 2, 2009 Hi Thomas, unfortunately you can't use a different amp with the L7 set up as it is an optical connection from the head unit to the amp, you can't even run new cables as the head unit does not have analogue outs when coded to a car with the L7 system. Can you not find one from a scrap yard or used on ebay?? Link to comment Share on other sites More sharing options...
u2cpooh Posted February 2, 2009 Report Share Posted February 2, 2009 I found several L7 amps, but they all are for 3 or 5 series. Are they the same or no? Link to comment Share on other sites More sharing options...
gizze Posted February 2, 2009 Report Share Posted February 2, 2009 Have a look on RealOEM.com Online BMW Parts Catalog and see if the same part number is available for the different series. I know the 3 and 5 series ones are both the same. Link to comment Share on other sites More sharing options...
ante60 Posted February 18, 2009 Report Share Posted February 18, 2009 Hi, Thanks to this thread I've started the upgrade to my standard stereo install in my November 2005 520d. For anyone trying to remove the door cars from this month onwards a word of caution, do not remove the trim on the door pull, there are no locating screws behind it, and you are likely to snap off the top three locating lugs from your trim!!!! Unclip your door card by locating the door clips around the edge of the door card, Remove the cosmetic cover off the phillips head screw located on the front upper edge of the door card recess, and carefully pop off the Airbag logo cover. Underneath this a trox screw that you need to remove. After you have unclipped and removed both the posi and torx screw you can now remove the door card. Both mine felt like there were more clips securing the card in place, but it was just the tight fit of the door card along the top edge. With a little patience you will be able to get it clean off the door. Fitting is the reverse, but I found it easier when fitting the door card along the top edge not to refit the tweeter cover. This is made if thin plastic and can be fitted once the top edge of the card is located (which is a cow to fit if you leave the tweeter cover in place). Take it slowly and you will not have any problems. Fitting just the tweeters alone has seen a significant improvement in the overall sound stage and puts back to the missing "top". BTW part number for the tweeters is: 65.13.6.978.631 All the best. Tony Link to comment Share on other sites More sharing options...

The 275 can run from the power wires that are in the Blaupunkt 2.5m adaptor lead. With the larger amps it's best to run them direct from the battery in the boot, but the 275 will be fine. There must be somewhere behind the glovebox in the 5 series it will fit. B Link to comment Share on other sites More sharing options...
ad525d Posted April 3, 2009 Report Share Posted April 3, 2009 Right, ordered the L7 tweeters (bmw take around a week) so picking them by coming friday. Cost £40 each + vat + cradit card charge = £95 Received the tha-275 amp today and the necessary plug n play cables ..... cost £190 question!!! the amp only has front channel, so will the speakers in the rear shelf go slient? (i have not installed it yet since i am waiting for the tweeters) if anyone has this setup please do let me know also behind the glove box, the access to insides is blocked by trim panels and i am a bit lost on the removal (another reason why i was unable to test if the rear speakers will work) ..... a guide to an audio install for the E60 would be much appreciated :) thanks Link to comment Share on other sites More sharing options...
gizze Posted April 3, 2009 Report Share Posted April 3, 2009 If you look at the harness the rear in and rear out cables hook together when you only have a 2 channel amp. Link to comment Share on other sites More sharing options...
ad525d Posted April 9, 2009 Report Share Posted April 9, 2009 Hi, I have completed my first audio upgrade tweeters and amp for fronts .... sounds sweeter (will upgrade to 5 channel / sws subs in the future but not now) But i have a question, The amp can run safely @ 2 ohms but taking into account that now 3 speakers are being run by a single channel (one side), if speakers are wired parallel, it comes to 1.3333 ohm load ...... which is not safe can someone shed some light on this!!! apart from this concern, everything does seem to work just fine, or maybe my calculations are wrong?

roydriessens Posted April 22, 2009 Report Share Posted April 22, 2009 Hi Thomas, unfortunately you can't use a different amp with the L7 set up as it is an optical connection from the head unit to the amp, you can't even run new cables as the head unit does not have analogue outs when coded to a car with the L7 system. Can you not find one from a scrap yard or used on ebay?? Sorry to drag this back up for my first post. For the basic system, does that have an analogue out somehow then ? Just wondering if it would be possible to use another amp as the Blaupunkt one. As far as speakers go, I found this nice set, that's supposed to be a direct swap for the existing ones. Can't seem to link directly to them though Link to comment Share on other sites More sharing options...
gizze Posted April 22, 2009 Report Share Posted April 22, 2009 Basic system is just speaker level, so any amp which takes in a hi-level input will work. Still worth getting the Plug and Play harness though. Hi-Fi system outputs a balanced line level - but still over the regular speaker outs, you have to code the radio in a car that is coded for Hi-Fi to get it to switch. DSP/Logic7 system outputs optically over the most bus network. Link to comment Share on other sites More sharing options...

I'm a correct in asuming that it's a full range signal sent to that midrange in the back ? Link to comment Share on other sites More sharing options...
fonefixer Posted May 23, 2009 Report Share Posted May 23, 2009 hi, have read all the posts and still a few issues i dont get ... ive got a e60 535d .. with standard stereo & prof nav.. so if i wanted to upgrade i would need... Blaupunkt THA-555 pnp amp. BMW plug and play cable with 5.5m extension. DLS R4 speakers. 2 earthquake SWS-8 subwoofers 2 x org bmw top hifi (logic 7) tweeters - the grills i have fitted as standard wiring from amp to 2 subs and to wire in the amp 1.this is the part that lost me do i need 2 x DLS R4 speakers sets? 2.whats the best wiring to use ? 3. do i have to wire the car speakers seperately or will the loom and the tha-55 handle all that .. 4. do teh tweeters have wiring pre installed in the door - ready to go ? 4. if its a 5 channel amp how do i wire in the 2 subs ? 5. i gather that all wires need to be put thru the passenger side (rhd car) 6. i hear a lot about feedback coming thru the speakers - anything to stop that ? i suppose thats it for now... thanks for your help in advance guys..!!

gizze Posted May 23, 2009 Report Share Posted May 23, 2009 You don't have to buy the DLS speakers at all, and if I were doing it again I would stick with the speaker already in the car and just add the BMW Logic7 tweeter, this comes with the bit of cable that hooks into the speaker in the car. The plug and play harness handles everything, although.. only if you keep the existing subs, if you change the ones under the seat then you need to run new cables from the 555 amp, this would be the only rewiring you do, just amp sub out to subs, even though it is mono there are two outputs to make it easy. I would run them down the passenger side as there is a massive 12v cable running down the drivers side. I never had any problems with any noise, even with the head unit witched to aux and full volume. Link to comment Share on other sites More sharing options...
DaveP Posted May 23, 2009 Report Share Posted May 23, 2009 Hi Guy so does my car have tweeters in the front? (Waiting on BMW to get a new sunroof in stock - they say it was broken, I say they broke it - too difficult to prove, so instead of £2k fitted it is "only" costing me £600 - bargain! cough) Dave Link to comment Share on other sites More sharing options...
CarMad Posted May 23, 2009 Report Share Posted May 23, 2009 Tweeters will be in the corner of the front windows behind the grill. Link to comment Share on other sites More sharing options...
gizze Posted May 23, 2009 Report Share Posted May 23, 2009 Hi Guyso does my car have tweeters in the front? Dave No Dave. I would get some L7 tweeters ordered for it, makes such a difference. You could then add the blaupunkt 275 amp for around £150, this gives 80wpc for the fronts and subs and is a really easy install. Link to comment Share on other sites More sharing options...

Please help!! Im a novice and dont want to get ripped off or buy the wrong gear. Thanks Richard Link to comment Share on other sites More sharing options...
gizze Posted June 10, 2009 Report Share Posted June 10, 2009 They are the 4ohm version of tehSWS-8, there is also an 8ohm version, that is the one you need. Then when you run a set of wires to one and another set of wires to teh other the amp sees a 4ohm load, which is what you want. Link to comment Share on other sites More sharing options...
gizze Posted June 10, 2009 Report Share Posted June 10, 2009 Prices may have gone up since I posted this, teh Euro is rather strong at the mo. If I were doing it again I would probably consider buying the 275 amp and the L7 tweeters. Or the tweeters, 555 amp and the sws-8 subs. I wouldn't change the speakers.

ric_vr6 Posted June 10, 2009 Report Share Posted June 10, 2009 How good does the system sound? I took it to a local audio shop and they qouted 3k, this was foe audio stream amps, hertz speakers, an Eq, and a 10" sub, they said this would sound a 100 times better than what you guys say. (but they would say that wouldnt they) If this sounds good then i think its the route il take......cheaper too. Link to comment Share on other sites More sharing options...
