Upgrading the D2 Audio

[Markiii]

Been a while since I've worked on the audio, as got sidetracked by more urgent things however back on track now

Genesis Amp fitted,

Sub box made to fit inside the spare wheel, not as hard as I'd feared. JL 12" low profile sub installed.

Just waiting on my DSP and speaker cable to arrive before getting things connected up

Which DSP are you using? I presume thats for optical out on the Joying HU?

[Markiii]

Joying has both Toslink and Coax SPDIF outputs

So ordered one of these

https://www.minidsp.com/products/car...-dsp/c-dsp-6x8

its very reasonably priced, gets some great reviews on some of the US Car Audio boards and has great support.

I'll report back when i get my hands on it

Interesting unit. Marcel and I have been looking at the Helix Mini-DSP which appears to be very similar - 6 channels and optical on that though, no spdif.

Looking forward to your results

[Markiii]

Helix gets good reports on the car audio forums as well

[Markiii]

well that arrived quick from Hong Hong

[Ronin]

Have you fitted it yet? any alternator whine or pops/bangs on turn on?

[Markiii]

not yet been away for a week, will have a play this week

[Markiii]

first thoughts, physically it looks a very nicely built unit.

Contents include

Main Unit
Wired remote
Remote Cable (RJ11)
Micro SD card
USB adaptor for the Micro SD to plugin to you PC
USB Cable (for connection to the PC)
Terminal block connector for Power, Remote turn on and High level inputs

Not that this is going to affect my use case but the High level inputs have a max input voltage of 8vRMS which to me sounds low for speaker inputs.

Having downloaded the config tool it seems very easy to use, and does allow you to pick any input, sum any inputs and send the results to any of the outputs. All before you play with the DSP and time delay functions

My plan thus far is to have

SPDIF + 1 Analog input routed to front door speakers (that 1 Analog will be a seperate feed from a NAV unit. (that will make more sense later)

SPDIF routed to rear speakers

Analog SUB input routed to the SUB output. I could derive this from the SPDIF, however I want to have a separate Bass volume control at the cockpit end, and I thing this is an easier way to achieve it. We will see

The remote has been described on the minidsp forums as somewhat over cased. And thats true, its a good 3 cm deep. My plan was to mount in the gap above the ash tray. Thats going to require de-casing it and a custom bezel, but I was expecting that tbf.

[Markiii]

once I've figured out a mounting location for the DSP my next job is to run speaker cables from the boot and RCAs from the headunit to the boot.

Any advice on the best place to route as I suspect getting trim panels off will be the usual ballache.

can speaker cables be got into the doors easily or is there a multiplug entry to the door as per some of the more difficult cars I've done this on?
