retrofit from stereo to s676a

[Silverstar]

Dave I have the factory standard subs with enclosures here should you want them, I can do a very good price if needed. But I would have to question going down this route, at the end of day you will have a factory standard system which is limited in performance and going the aftermarket route as I have done in mine will yield better results with less complicated install.

Thank you

See now this is my quandary, if I go the OE route, yes it's a lot of work in theory, but at the end of the day it's OE, which is what I like to see. But if I go down the aftermarket route using the Vibe amp then it's straightforward plug-n-play, a couple of tweaks and you're done. It's also hidden away so you don't see it, even the matching sub is under one of the seats (it's a slimline sub).
Now I don't have a big issue with my system since I retrofitted it all, in fact I think it's very good quality, my issue is when the roof is down I'd like to be able to hear it a little better, nothing too grand, just enough, after all I'm driving with the roof down so I'm not expecting it to be full beans clarity. With the roof up and playing good music mine is a very decent system with a good level of sound already, I can hear it, I can sing along (NO, no videos will be provided on my channel ) and I enjoy it, especially when compared to the God awful quality from the base system that was in it to start with.
So this is a lot cheaper without the hassle, simply plugs into the headunit and you don't have to run any extra wires...

Are you sure we can't entice you to make a sing a long video? I think the Vibe amp makes sense for what you want to achieve and from experience adding an amp even without adding the subwoofer(s) makes a huge difference to the sound quality, the subs just take it to the next level.

FWIW,

I’m midway replacing my 677 system with the Audio Fischer Match 10 DSP system.

Due to other 1st world issues I’ve changed all the speakers bar the subwoofers to upgraded non BMW versions..

The 677 amp is still there..it really struggles to generate enough power to give a decent sound level at say 70 mph especially on dual carriageways etc..

After a few minutes it overheats and I get ghastly and progressively worse distortion…I first thought I’d burnt the speakers out..on cooling down the quality as such returns …

I’ll get the new DSP/amp fitted this winter..

Hi Dave
I’m thinking of fitting the Vibe slimline under seat sub to help with the base after coding my basic system to $676, would you be able to tell me the best place to pick up the high level audio feed, can I tap into the rear speaker below the seat belt mounting (left and right) or do I need to pick it up from the head unit. Or use the low level feed from the Vibe micro 65.4 amp powering the mid and woofer speakers.
Thanks, Mick

I'd gowith the output from the Vibe amp as its designed for that, no messing around then

Surprisingly though I decided not to go this route and actually opted to fit the full 676 retrofit. A lot more hassle, far more expensive but it does sound good

Cheers Dave, in that case I presume I also need to run a wire from the remote out on the amp as well and live/negative from the fuse box,
I’ve been reading up on the 676 retrofit and it’s definitely a step too far for me

Yes you'll need the power and remote wires, this is all covered in the manuals to come with the amp and sub (I managed to download them previously).

Retrofitting the 676 was a lot of fun. I built the loom from scratch which is speaker wires, power and canbus from the front of the car to the amp and then all speaker feed wires. Used all the correct guage wire, hand twisted the speaker pairs and fibre taped them in their respective routes, crimped and plugged them all. Removed all the trim pieces in the boot and behind the seats.
But can you guess what the hardest part was?
Trying to find the two grills for the subwoofers! There were no complete bulkhead panels with them in available anywhere, but I managed to get one grill from the UK and finally find the other one in Florida!
Oh it was all fun, but it was worth it, absolutely love the audio now, much louder and the bass from the subs is really good.
