OK, considering a "boot build" for a 10" sub with Vibe mono amp. Not sure which is the best way to run it - line from MFD or disconnect the rear speakers and use the high level inputs on the amp. Question - are the line outs from the MFD fixed or variable output. I don't really want or need to introduce an additional amp for the fronts as I think the on-board one is probably good enough but I don't want to be mucking around with levels all the time for the sub.

Interesting question. I believe the ones at the bottom right of the main quadlock connector are variable and I assume that the ones in the smaller connector under the fan are fixed volume for connecting to external monitors where you'd want to use headphones.

Actually, I'm doubting myself now. Hopefully somebody can give you a more definitive answer. Shark 90?

Looks like nobody knows Wega!

As far as I understood you will need a high-low adapter (helix is a name that is often mentioned in our boards) to connect an amp to the columbus. It doesnt have a line out for an amp.

Er, it does - the question is if they are fixed or variable! I wouldn't need a high - low as almost all amps have high level inputs anyway.

Come on guys SOMEBODY on here must know!

BUMP

Where do you see a connection for an amp? You will need an adapter. (Helix Hi-Low)

There is no line out on a Columbus/RNS510. All you can do is take the speaker outputs and change them in a signal for an amp.

Oh this is *******s - has ANYBODY done this? I've had several people say that the MFD3 has line outs and now I'm not so sure after Magic62's picture!!!

It really doesn't matter to be honest because I think the easiest route is to just break into the rear door speaker feeds and shove them into the high level input on the amp. I would imagine the cables run along the sill tray I just have to figure out which one is which! I don't see why I would need a high / low adaptor in that case unless I'm missing something?!!!

Most of the users on the german board use the Helix Hi-Low adapter. Think it is mainly because of the sound quality. Should be better with a low amp input.

Just read some of the posts in the german board. All the members who added a subwoofer to the columbus did it with: Helix adapter, amp, sub.

Where do you see a connection for an amp?

On the RCD510, it's the (unlabled) pins 2 (right +ve), 3 (earth)and 8 (left +ve) on section C of your diagram. Are they definitely not connected on an RNS510?

This is what I found from a RCD510:

All the current headunits from the VAG group are connected to their amps by CanBus, so they wont need an amp output.

(this is also why many wrongly coded units dont work with the original speakers).

There might be a difference between the US/Canada version and the european version.

I see this is a few months old, but I want to throw my opinion in.

On the 26-pin plug, I thought pin 5 and 18 was audio out. Use pin 24 as ground. Wether it is variable or not, well...

Old subject i know but is Multi pin connector 2 - pin 11 would this be know as ignition live or permanent live?? I need ignition live to connect to a helix block line converter to run an AMP??

Thanks

Anyone ??
