Hi all

I have just had some work done to my zed's audio...

My zed

59plate GT. Has all that integrated satnav stuff but not the improved 2010+ kit.
The back is stripped out - got rid of all that foam packing; going to work on sound deadening etc.

Reasons to do

Unimpressive Bose sound - wanted more volume & bass.
Bose sub is fat, ugly and, once gone, will give extra boot space.
I had an old amp (JX 360.4) and sub (JL 8w3) lying around.

What I agreed with the audio guys

Swap out front speakers and tweeters. Connect to new amp and sub, to be mounted in the space behind the silver strut.
The amp fits on top of the existing one; the sub fits neatly over the space.
Initially I hoped to lose the horrible satnav kit - doing this stopped everything working so it stayed.

New kit was JL Audio too. JL C1 690 components (woofers, tweeters) and TWK 88 controller DSP.

The build

Not straightforward. The fitter discovered that the speakers were active, so needed some fancy re-wiring for the new ones (haven't a clue beyond that so don't ask).
Door speakers fitted and dynamatted.
The TWK unit does something beyond making my bank balance smaller. Picture shows glowing red light, so cool.
The new amp is mounted over the existing one (I think).
The sub was mounted with brackets and fits perfectly. That's with a stripped-down back though.
There's a switch to control overall amp volume (inner) and sub volume (outer). It's been mounted in the auto transmission cluster.

Conclusion

The sound is exactly what I wanted. Much, much better than what was replaced. The build sounds a bit of a cludge, but I think the fitter did excellent work, and we were limited by budget, by use of existing amp and sub, and by the original setup.
This isn't for audio purists. I have a rattly car with a massively loud exhaust which isn't the ideal sound stage. But I got what I wanted - the Ramones sounding brilliant.

 

Cheers, Laurence

What's happened to your Snow Mode button (pic 3)?

Chubbs,

 

I had to find out about this. No snow mode, this feature only appeared from 2011, so the button was a blank.

Very interesting upgrade mate :thumbs:

 

I know the 2009 infotainment system & Bose has quirks so it can't have been an easy job.  Especially when it came to using the kit you already owned.

 

When you say that everything stopped working when you removed the Sat Nav can you go into any more detail?  I've removed my head unit but kept the Nav 'brain' behind the driver seat so I could still see what the A/C controls were doing.

 

Good work sir!  I hope to hear it one day :)

Paul, I didn't get an explanation from the fitters about what stopped working (forgot to ask). I assume it was console stuff. I'll ask next week.

 

I'm there at the Cambridge workshop day so we can swap experiences then,
