Suddenly got fader option after wiring speakers

[WozzaB]

This one confused me to be honest, I fitted a small 4 channel amp and the back of the CD unit is 6 channel, I didn't realise initially, so I only had the front tweeters and rear speakers amped as the front door speakers are on separate pins.
I've always only had the basic balance with L/R as an option in sound settings, but I wired the front door output from the unit to the front input on the amp along with the tweeters that were already wired in there, and the sound settings has now changed from balance to full fader, which I've never seen before.

So I guess the unit has sensed something has changed, I thought you'd have to code this in to be honest. It sounds crap at the moment to be honest, and I've had enough of farting about with the wiring so I'm booking it in to the let the pros sort it

Does it sound worse than it did before you fitted the new amp?

I think, and am happy to be corrected, that the extra two channels on the standard amp are for the front centre-channel and subwoofer, so you should have just wired into the existing fronts and rears.

What was the amp you fitted? Is it a ‘high-level’ design? In as much as it uses the speaker outputs and amplifies them?

Just interested!

Cheers,

Nick

I've gone through the wiring and the fronts are just the tweeters and the front doors are on separate pins, I fitted an active sub and I originally thought the same as you, but there's no low level output on the front pins and the sub switched on but no output, so only highs for the tweeters on the front l/R pins, so I tapped into to pins for the front door speakers and the sub worked great.

It's high level input amp connected via ISO T harness.

But today I've farted about trying to get amp to power all the speakers, on paper it should be fine, but I think I've got a dodgy connection or I've messed something up, as now the sub has lost some oomph and the rest of the speakers sound a little worse, so it's something I've done, but I have honestly had enough of dragging the CD unit and trying to sort it, so I'll let a shop sort it.

The fader suddenly appearing today was what threw me, it's never been there before

These pins power the front door speakers.

I just realised I already started a speaker question thread, apologies mods for an extra one!

I went out this morning and wired everything back to how it was before I messed about with it, the sub as back to normal and sounding great, the speakers sound decent again, but I'll still have to get the front door speakers running off the amp, but I'll take it to a pro this time

The fader has disappeared and I'm back to the normal balance control again

Good that it’s back to normal, it sounds like you wired something out of phase, and I’done surprised that the tweeters and front speakers are on different pins…

I think that those pins are for the subwoofer (the Seat Sound sub isn’t powered) and for the front dash centre channel. The pins marked RL, FL, RR and RL I’d assume are the door speaker connections.

I reckon that the system saw a load when you connected the amp to those other pins and opened up the fader menu. It sounded bad as again, I assume, it needs to be configured correctly to enable the Seat Sound settings.

@East Yorkshire Retrofits will no doubt know how to answer this one correctly.

Let’s see what your pro guys say.

Good luck buddy!

I've got the bog standard speaker setup and have the same 'Balance - Fader' menu.

Bog standard sound here too

You're probably right with the unit sensing a load change.
I think I had a dodgy connection and the sub was probably only getting one high level channel, I just redid some connections and the sub is back to it's best.
When I disconnected the pins I circled in red, the front door speakers stopped working, so it seems they do power the front doors, it seems a strange way to do it but that's how it is.

I'll give an update once the shop had sorted the amp/speakers, cheers

That's what I had briefly when I tried to add the front doors to the amp, but now I've wired it back to standard, it's gone back to balance only
