I'd wire them directly to the rear output on the stereo. However then you might as well run new cables to the front too and just buy an iso plug (leaving the stock loom intact). Any aftermarket stereo will be much more powerful than a stock amp anyway. Its a bit if work but not difficult by any means.

Do you mean find out which speaker cable is the rear and fit a phono cable to the end of them then plug them in the back of the new head unit. Wasn't really going to bother running new cables mate.

 

No phono, literally run direct cables. Can be done for about £15 and and hour or two of your time

 

Can you take a picture of the harness and plugs that you are connecting in to?

 

Hi

I've just installed a pioneer head unit in my TT after a lot of of reading and asking about for parts. It's eventually fitted and working but the rear speakers are really quiet, it's a non Bose system in it. Does anyone have any idea how to sort it?

Cheers in advance

Here you go.

 

Wow. [smiley=bigcry.gif]

 

Wow. [smiley=bigcry.gif]

Tell me about it!! Harness for everything in there lol.

 

Rewiring is still the best option IMO. Cleaner too. Can't help with you spaghetti junction though as I've been fully amped in my TT within a day or two of owning it

I had to buy an extra hardness as had no power to the new headunit. Don't really want to pull panels apart to rewire it mate, I've connected the blue wire from harness to headunit, just really pushed it through the hole and taped it, do you think it would make a difference of I used bullet connectors? When the original headunit was in I thought most of the sound came from the back but not now

 

To be honest I'd bin that mid section if it only.helps to power it. If you get a tiny screw driver and look in the pin end of the stereo harness side you'll see a tiny tab you can push down to release the pins. You just then need to colour match the positions with what you can see on the car loom. Its easy enough, really. Using the stock amp however I can't help still I'm afraid. OEM is worthy for the bin as far as I'm concerned

 

I think I will stick to the Bose one looks a bit of a nightmare to me [smiley=bigcry.gif]

 

Also I do think it would be worth buying a small pack of bullets yes. Then you can use them anyway for other small 12v projects you may choose to do later

I think I'll just keep it now mate it's there now and seems to work and you don't see of once it all tucked away and headunit in, just annoying with this rear speakers being so quiet. Never had so much brain fry fitting a headunit usually straight forward.

 

You have the wrong harness there... If you look, your red plug only has for wires which means it only covers either the front or back (in your case the front). You will see at the opposite side you will have six wires. The two inner ones are the remote switched positive and then the negative. The four outer wires will be your front right and left and then your rear right and left. Who ever sold you that, has sold you an A3 harness.

 

Does your new head unit have amp out (RCA) connections?

 

If you have a look at my thread, "Another Bose or not Bose" which should be near this thread, you can see the difference in the wiring harness plugs. Plus I have a little wiring diagram which shows you the six connections...

Here is the harness I bought mate

I am getting some sound but really nothing compared to the front.

 

Yep... That's your problem... Its for the rear amp'ed TTs. Yours has the six wires which can only mean that its front and rear amp'ed...

Do you have RCAs on your head?

 

If so, you could use one of these:

Those nexus links never work on my tapatalk app :-/

 

Shame your not closer as I have a spare iso harness that will do the job... It looks something like this:

Mines is not the bose I've checked that already.

I thought mines was the only rear amped speakers on my tt? Yeas it's a pioneer bluetooth headunit and has RCA's connections at the back.

 

Use the RCA adapter... You will get better sound quality along with better control... The heat shrink'ed part of your iso kit are resistors that reduce the loudspeaker output down to accepted amplifier input signals. As with all audio, the more you pay, the better the quality and those Halfords leads are terrible. You're honestly better off using your RCAs if you can.

Also, on this tech page you will see what I'm on about with the four wires and the six.
