Stealth system installation

[Squeeguk]

Thanks, yeah will post up my settings as soon as I get a chance to re set the system up from scratch with my oscope. Biggest thing is finding out exactly when the HU starts clipping.

I am using the high level speaker outs from the RNS, I did not have the VW amp installed in my car. I would like to try and see the differences when recoded via VCDS to run low outputs too. Lot's to play with and so little time.

I will send you a pm with regards the loom and I am sure it would work with the RCD 510 / 300 as the speaker outs are the same from memory.

Stage 2 will be another Hertz HDP4 amp running a sub and the rears with a couple more wires run to the front to run the woofers in the 3 Ways on 2 channels and the Mids and tweeters on the other 2 channels. But wanted to get a baseline for this first. Stage 2 will be quite a rework though. Not to mention the cost, lol. Another £700 just there.

For those who are interested in the clipping rates of the RNS 510, I was able to finally do some preliminary testing yesterday afternoon.

I tried with the speakers set in both high output and low output modes (for sound system). The results were interesting and a little disappointing.

I played 2 reference tracks, one at 50Hz 0dB and the other at 1kHz 0dB.

With the 50Hz track, the unit started clipping at volume level 9, while with the 1kHz track, clipping started at 19. These are both out of a total of 30 on the volume control. When switching to low output, the values did not actually change much, being at 11 on the 50Hz track and 17 on the 1kHz track. What I find really odd, is that both times, the clipping happened only on the bottom end of the sine wave and not both as per usual. I would really like to get this verified by someone.

So, my next step now is to setup my Bit Ten using the 18 volume level setting as max for now.

So it clips the bass but the treble is untouched?

When you say switching to the low output? What exactly does that mean? If I've got my RCD510 speaker outputs going to an LOC what volume level do you suggest as using for my new 'fake' max? bearing in mind i can compensate a little for bass roll off with my LC2i

It clips on both the 50Hz (bass) and the 1kHz (treble) tracks at the relevant volume levels I posted.

The RNS can be setup to be used with a factory amplifier or Dynaudio system. As such, using VCDS, you can switch the outputs from a high level output to a lower level output for those systems. There is a subtle drop in volume level, but to be honest, I would just stick with it as standard as you don't seem to gain much if anything using the lower output levels.

i see

i dont think the RCD510 can do that anyway

I also just checked and i currently have 15 set as my maximum

Very cool...

[jedi-knight83]

just got my new hertz HSK163 in.

this new version are far better made than the previous gen!

and the sound  ...... so smooth.

Question though... did you leave the crossover settings as standard or did you raise / lower the db settings for the mid and tweeter?

Mine sounds like it needs a tiny bit more mid range but means stripping my doors apart again to get to the crossover.

[Squeeguk]

I left the crossovers in standard mode. Figured it would be best, with using the equalizer on the Bit Ten D. I know what you mean, I will be tuning mine for a bit more midrange too. Seems a little lacking on that score. It did however sound much better when I was using the Focal JMLab demo discs instead of the mp3's on the HDD.

How did you mount the speakers? Do you still need the mounts? I was going to be making up a few sets today for stock.

I used my old mdf rings but they are a bit crap.

If you are making some and i have to take the door cards off again anyway to change the cross over then i will def have a pair off you.

Re the mid range.. the cone sits a bit further forwards compared to the previous ones i had in there and bit worried they will be very close to the plastic on the inside of the door.. did you have any mounting issues with yours? Did you have to space the mdf away from the door at all?

[Squeeguk]

Nope, didn't have to space them at all. They sit perfect with loads of space to the grille. I did have to create a rebate to clear the plastic surround as the screw points are lower than the lip.

Let me know when you have them made and ill have a couple off you.

very very neat install--i took my amps out so i can get to the spare,but i now miss the bass out of the system--

[Squeeguk]

Thanks very much.

Switch to 3 ways in the front and amp them. You will be amazed how good the bass is with it just like that and no sub.

[Andy]

how much for you to supply and fit the 3 ways and a put the amp at the side of the boot well

You got pm.
