You're missing the rear speakers?
(pin 1,4,5, 8 )
That is really strange
This is my block and is fully pinned (also b and c block):
My car has all options (tv, hifi prof dsp, navi, bluetoot etc etc etc), so I also have the subs and speakers behind the seats (hifi professional)
Hifi professional is option S677A in the bmw vin options check.
What are the last 7 characters of your vin? I have LR90594
I'm not sure but it looks like your dsp system is totally differently wired than mine
based on your picture, and the text in the sticker, you've got navigation?
Do you have a picture of the top of your headunit with all the stickers and part numbers?

sk93, which pin are you using to turn on your amp?

Re: Carver/DSP Delete - easier than expected
Hi I just installed a new head unit in my 03z4 yesterday only to find out that I have dsp and this have no sound from my system with the new head unit. Based on the title of this thread im wondering if I can install a different amp and get my stock speakers working with the new head unit I installed?
Thanks,
Nate

Re: Carver/DSP Delete - easier than expected
there's a pin in the main amp plug that is 12v switched. I'm using that.igeak691 wrote:sk93, which pin are you using to turn on your amp?
What pin it was, I can't remember, but it's definately available in the standard amp plug.

Re: Carver/DSP Delete - easier than expected
That's great news...so you took apart the harness where it plugged into the amp and then wired it yourself into the new aftermarket amp? No custom wiring up front from the stock harness to the aftermarket head unit?sk93 wrote:sure can03z4 wrote:Hi I just installed a new head unit in my 03z4 yesterday only to find out that I have dsp and this have no sound from my system with the new head unit.

Re: Carver/DSP Delete - easier than expected
exactly. ZERO wiring required up front, as everything you need is contained within the AMP loom plug.03z4 wrote:That's great news...so you took apart the harness where it plugged into the amp and then wired it yourself into the new aftermarket amp?

Re: Carver/DSP Delete - easier than expected
I Hate to bother with so many questions but I'm no electronic pro...I've done probably 10 amp/ sub installs and countless head unit installs but this dsp elimination is a first for me

Re: Carver/DSP Delete - easier than expected
Tis quite alright. It was my first too, and I really wish I'd taken photos of the plug decomposition.03z4 wrote:I Hate to bother with so many questions but I'm no electronic pro...I've done probably 10 amp/ sub installs and countless head unit installs but this dsp elimination is a first for me
If memory serves, the power and IBUS wires are obviously different to everything else, and the four remaining thicker wires are the subs.
From the rest are two lineouts (one + and one -), and then the remaining (10 wires remain I believe) are all speakers.
To discover the two lineouts, I used a spare speaker, turned the headunit on, and put one wire to a terminal on said speaker, then went through the other wires tapping them on the other speaker terminal until it made some noise.
If I went through all the wires without any noise, I'd mark the current wire as a 'speaker wire', stick another wire on the terminal and repeat the process.
It didn't take all that long to find both lineouts
You could probably take each wire through the speaker, then direct to ground to find them even quicker maybe?
For detecting the speakers, I used a 3.5mm jack to 3.5mm jack cable plugged into my iPod.
I then repeated the process for finding the lineouts, marking each pair.
You could probably use a multimeter here, but I was getting spurious results which I put down to a dodgy meter and/or dodgy ground somewhere...
Once I'd got the pairs sorted, I used a single AA battery to work out the speaker polarity.
This involved taking the speaker covers / doorcard off, but wasn't too much effort.
Then it was just a case of wiring it all up - INCLUDING the passive crossovers for the tweeters.
As I say, it took about 4 hours from start to finish. The old amp was already out, but the wiring was still in the factory location and condition (eg, I'd not pulled apart the plug yet).
Knowing everything I do now, I reckon it's a 2.5 - 3 hours.
Having a pinout would drop it to less than an hour

Wow thanks so much...I can't wait to get digging into this! Do you still recommend the alpine amp you purchased?

Re: Carver/DSP Delete - easier than expected
Alpine PDX-V9 order placed...once that gets here I can finally work on getting my speakers working again! Been forced to take my blue tooth speaker to work with me and set it in pass seat so I don't have to deal with silence during my 1 hour commute!

Re: Carver/DSP Delete - easier than expected
did you have to put RCA cable ends on the signal wires from the head unit so they could plug into the amp?
