Hey!  It's been a while...  I think we're going to try to have some new material up soon - it's only been what?  A year?  No big deal... Anyways, I've had a surprising number of requests for more information regarding the DIY speaker cables for Sony's evil proprietary connectors, so I thought I'd make a new post as a follow up that will hopefully clarify what's involved in the procedure...  Shall we?

As I mentioned in the original post, the two things you'll need are some speaker wire and a few 22-18 AWG .110 insulated female quick connect tabs (widely available online and in electronic component stores).  Let's start by looking at the quick connects themselves...



One side of the connectors is flat, and the other has two small loops that create a small groove - that's where the pin inside the receiver will sit... you'll see, gimme a chance here...


See the two pins inside each port?  Your quick connects are going to fit around the outside of both pins...

You'll want to make your cable just as I described in the original post; there's not much to it - but you'll want to make sure of the polarity of the speaker wire - most speaker wires will have a silver streak on the negative side, while positive is usually all copper.  Strip the ends of your speaker cable and then insert each end into a quick connect tab and squeeze it shut with a pair of pliers.  You should end up with something that looks like this...



So take the first quick connect tab - and connect it around the appropriate pin (+ or - ).  Here's a close-up of the first quick connect in place...




If you look closely, you should be able to see that the pin inside the receiver's port fits perfectly inside the groove of the quick connect tab...

Now push the other pin in place... It should look like this...




Both quick connect tabs should now be firmly in place...


et voila!

Now all you have to do is attach the other two ends of the speaker wire into your speaker (again, taking note of polarity).

And that's it!  I've had my subwoofer hooked up with my homemade cable for a few years now without any problems...  A few readers have also mentioned other Sony receivers cursed with these connections - here are the models (I'm aware of) that have them.  If you know of any others, let me know and I'll add 'em to the list:

DAV-C450
DAV-DX155
DAV-DX255
DAV-DX315
DAV-HDX589W
DAV-S400
HCD-DX375
HCD-HDX465
HDX267W

I hope this helps!

Until next time,
(hopefully sooner than a year from now).

How would you go about replacing the speaker wire on the back of the MHCEC909iP mini system's speakers? The thin speaker wire broke off after my daughter knocked a speaker over.

Oh, and thanks for the post.

Hey David, sorry for not getting around to your question, sooner... I've searched, but haven't been able to find a picture of the wire/speaker connections on the MHCEC909iP... However, I suspect its cable/connection is different from the kind outlined in my original post - I'm pretty sure these connections are only used on Sony's home theatre systems, but I could certainly be wrong... I'll update the post if I find anything out... Thanks for your question!

This is amazing! Can I use a 16 AWG or 12 AWG wire or will it be too large?

Hi Giuseppe!

As long as you can connect your wire to the quick connect tabs it shouldn't matter - I think both would work.

Hope this helps!
