E87 base audio upgrade

Post by Dogpipebeard » Sat Aug 10, 2019 8:43 pm

I'm about to upgrade the base audio in my new to me 2006 E87.
The HU has been swapped to a Professional already but needs to have the Aux recoded.
I've already put components in the doors. As I immediately then ordered a leather interior I'll have to do those again though :roll: . No problem with that, second door took me half an hour.

Input on the two options please:
1) Stay OEM ish, recode HU and fit USB hub, add plug and play ish Audiotec Fischer 5 ch amp with DSP and their under seat 8s.
Pros: OE look, relatively straightforward.
Cons: base audio spec means no amp wiring harness in rear (can't find one) to take advantage of plug and play ease. The tweeters, mids and 8s share a channel. I don't really want to amp the rears. Don't want a proper sub.

2) Go full aftermarket: DEH80PRS, Eton 100.4 channel, amp the components and new 8s separately.
Pros: Will sound good - had a similar set-up previously. Bluetooth OK and twin USB.
Cons: Aftermarket look, bit complicated, but doable. All in about a grand in cost, so more than OE option 1. Will be tricky to switch back to stock.

I have plenty of time off to do the installation, have done a couple before. I'm not convinced the amp isn't a bit thick for the boot floor recess (55mm). Floor might sit on the amp a bit, but they don't get that hot. Car is a keeper for a few years.

I guess I'm looking for folk to reassure me about option 2. The stock audio is a mess of coding and proprietary willful wiring. Who has done it and can share wisdom? Have seen a post on E90 where a guy does a similar install on a 120D. Not many other installs though: keen for pics of boot amp install especially!

What would you do?

If it was between the two of them I'd go with option 2, but what about an option 3 - Genuine BMW Alpine audio upgrade kit?

£350ish from Cotswold for an amp, two mid speakers, two tweeters and all wiring/crossovers needed. Not difficult to install, fully OEM, no coding required (other than coding in your pro HU). My car is base audio/Pro HU but had two hifi subs installed by a previous owner which are more than powerful enough to complement the Alpine bits.

Whilst I was installing it I swapped in the rear trim pieces from a Logic7 car so that I can install better speakers and a pair of tweeters at the back at some point. Tbh I'd genuinely consider another Alpine kit to do that, it's good enough that my original idea of a full Logic7 retrofit is dead and buried.

FYI if you don't amp the rears and you recode the car from base to hifi the PDC pings will apparently be uselessly quiet.

That's a good suggestion Nyxeris. For the 350 I'd get a sufficient amp and most importantly the wiring. Does it separate the door components and the under seats? I guess not if it amps the rears.

The car's going in to an indie tomorrow for stuff, one minor thing being the aux recode. Might get them to do hifi then too. The components I'm using have an external crossover and high pass so should be OK either way with or without the source signal eq

Eta: with components in the rear it might be ok anyway.
Just never been a big fan of rear sound.

Thanks for option 3!

As standard the Alpine upgrade kit only affects the front speakers, I referenced the rear because I would consider buying another identical kit to install for the back as well. Sorry if that wasn't clear, here's a PDF scan of the install instructions which will make it clearer than I can!

I think the under-seats are seperated already and they simply get amped. The kit is designed to be compatible with all speaker/HU combinations short of Logic7 (from which it's not an upgrade); the supplied crossovers seperate the A-pillar tweeters and the door speakers, the supplied wiring harness has multiple connectors (all labelled) and you use the one appropriate to the car's current equipment.

You could always ask the guy to test your setup - code the car to hifi, stick it in reverse and have someone walk up on it to test the pings, if they're too quiet then recode to base. Shouldn't take very long at all.

Don't apologise, I assumed the alpine kit would power the front 3 ways and the rears (4 channel amp). It appears though that it separates the door components from the underseats and powers those 4 channels, leaving the rears unaffected as you say. In pre09 cars the 'fronts' are I think the door + floor drivers per side.

So in short the alpine kit seems to do the job. Here's a link to a pic of the inputs/outputs for anyone else looking into it.

These are a bit too proprietary for me, but I like the integration.

Another plug and play wiring option seems to be this adapter kit. I mailed about it and the reply was a bit cryptic, but the build I mentioned in the first post used it and he's been doing them for years. Still trying to get my head around the stock wiring though

Would allow the use of any amp (incl. DSP) but have a non-invasive install using the stock HU just like the Alpine kit.

Anyway right now I don't even have aux in active and no USB plug :censored: hopefully tomorrow but I expect bumps in that road

As suspected, the indie refused to do the Aux recode because 'liability' reasons. So I've ordered the cable and downloaded the software and will do it myself. Tomorrow: attempt to remove center console to fit USB cable

On the audio front, currently swinging towards option '3.5'. Keep Professional HU but add non standard amp. Only if aux or USB work though. Want a quadlock adapter too so I don't have to butcher any stock wiring.

Sod's law continues. I removed the center console to put the USB port and cable in. Also needed to remove a 50p that was blocking the ashtray lid. On removing the HU, saw that it wasn't one with a separate USB in. :roll:

I did download NCS Expert and ordered a DCAN cable to code Aux though, and bought the 'right' HU and will pick up on Thursday. The seller will code Aux and USB for me.
Also bought a plug and play 6 channel amp with DSP, and some new under seat 8s. The new interior comes tomorrow so will redo the door card speakers with some foil damping sheets.

Sounds OK (CDs) already with the tweeters at least. :)

Satan interferes with my progress yet again. Steady rain all day means the interior swap has been postponed til tomorrow.

However, the audio kit arrived, I've finished the set up of NCS Expert on my laptop, and the car has been given a thumbs up from local suspension specialists, and will go in for new brake reaction bushes and alignment in 2 weeks.

Tomorrow:
Strip interior
Fit amp and 8s
Fit new interior
Collect and code new HU
Drink heavily :fest:

Would be very interested to see how this goes and would welcome any advice on a install.

Currently have pro hav HU with base audio, so looking to upgrade sound system. Ideally would like components up front, updated subs and all amped.

No idea how to do the above, as in do I have to

run RCA from HU?
Run new wires/ spice current loom?
Proper looms available?
4 ch amp for mids and subs?

Been a lot of years since I updated a stero. Use to be easy.

Again the OEM Alpine upgrade kit is a great option here. Pair it with genuine (used) hifi subs and it punches well above its price.

Cheers, I was thinking about this, or maybe using aftermarket amp to give better control over some uprated subs? read the crossover on the alpine wasn't that great?

Think I'm confused about is, if I use a aftermarket amp do I use rca from the HU and code it, or do I wire the amp from the front speaker sires (like the alpine kit).... Guess I would then need speaker to rca converter?

No worries.

Base audio doesn’t have tweeters or a second second sub, so you’ll at the very least need the speaker grilles and probably the sub’s wiring harness too.

There’s a sticky at the top of this section with all the options and diagrams I think - I can only comment on the bits I’ve done!
