hahaha! Somebody do this a post a photos please

Yeah wasnt expecting an instant quote over the forum but maybe would reveal those who are flexible and those who aren't. Piece of obvious advice guys - don't get caught driving an uninsured vehicle. They totally screw you and you keep paying for it for years in higher premiums. They dont care if its a mistake! Queuing up in a steel cage outside the car impound for hours certainly makes you feel like a criminal, its not pleasant at all. And then you have to pay through the nose to get insurance cover for an impounded vehicle, and points, and a fine, and an impound release fee. Ill never repeat that mistake.

IN10 was totally by mistake, mix up during the overlap period between getting the Z and selling the previous car. Previous insurer only extended my insurance for a short while on the old car when I thought I had told them until "I'd let them know when its sold, probably a couple of months". They had just switched to online insurance certificates (which I didn't check so I missed the new expiry date, stupidly). Im 38 years old, the car is parked on a driveway in SW20 London and needs SDP cover for around 6K miles per year. Im currently paying around £700 due to the IN10 which isnt bad but current insurer not happy about most mods and I'd like to do a few, nothing major like SC etc. I've got full no claims bonus and a single previous claim which was recovered from the 3rd party - somebody hit my legally parked vehicle. If any club friendly insurers are reading and think they might be able to help please PM me and we can go through the fine detail for a quote. Saving on my premium would be nice but my main purpose of looking about is because I want to mod the car a little without voiding my insurance or paying through the nose for the insurance extras. Cheers

Thanks, I always find the detail to be difference between a good and a great job! Yep new speaker cables were run from the amp in the glove box right through to the cross overs on the doors.

So.... Huge improvements made. Only focused on the doors this weekend. Applied a complete covering of silent coat absorber 35 to the door cards with cut outs for the door handle mechanism and speaker area. This has massively reduced mid and bass resonance in the door and it's now almost entirely eliminated, certainly no need to anything further. If you choose to do this don't forget to make some holes for the screws holding the door card to the door, the plastic trim plugs and the cabling for window controls. I also applied a patch of Dodo Liner Closed Cell Foam 6x8 inches behind the speaker on the Dynamat coated outer door skin for good measure. I also cut 45mm holes in the door sails so I could mount the tweeter properly. Did this using a 44mm ringsaw bit and a bit of dremmel to expand the hole slightly, checking with the tweeter as I went so as to make a good fit. The tweeters just pushed into the hole with a bit of force and certainly don't need any kind of fixing to hold in place. Imaging and high frequencies now hugely improved. Very satisfying! I'm now getting the quality I had hoped for when forking out for the original installation. Finally getting to appreciate how good the Focal 165 KRs are. Only thing missing now is real bass.... Next up is the sound deadening for the boot, floor, rear wheel arches and maybe even the roof. I'm seriously considering building a sub box for the stock location as I like a relatively stealth install and appreciate the little amount of storage space in the Z's boot. I'm probably gonna go for a 10" JL and use channel 3/4 bridged from the amp. I think a proper install for a box in this location will be critical. Will update the thread after the next round of work. PS. What's the best way of posting pics on these threads? (sorry if that's a stupid question)

I got number 71 kuro black with 36k. Picked it up back in July 2012. Mods so far listed in my signature with more on the way

Can't say no for £160, count me in

As a fellow Kuro GT4 owner I'll be watching your build thread closely. Just ordered spacers myself so nice to see what they will look like in your pics.

Whilst waiting for the foam rings to arrive I have been looking into further audio improvements and sound deadening. Ill be getting a sub in the near future so want to ensure the car is prepared and also cut down on road noise. I got in touch with www.deadening.co.uk to ask how to deal with my door audio issues and what else they recommend in terms of general advice and products. Here's what I got back..... For your doors, we recommend applying Silent Coat Absorber 35 to the door cards and Dodo Liner Closed Cell Foam behind the speaker, straight over top of your Dynamat Xtreme on the outer skin. This will improve the acoustics of the speakers and also cut down on that mid range resonance. Products: http://www.deadening.co.uk/products/silent-coat-absorber-35 (also available in 15mm) http://www.deadening.co.uk/products/dodo-liner-ccf9 (also available in 6mm) For the wheel arches and floor we recommend a 2 stage process, similar to your doors only with different products. 1st stage: Treat the metal panel with Silent Coat 2mm Damping Mat (alternative to Dynamat Xtreme, made to same spec) to reduce panel resonance and body boom. Use up to 50% coverage for most cost effective results or 100% for a fully comprehensive job.This product can be used on any metal panel in your vehicle, with the most common areas to treat being the floors, doors, sides, wheel arches, roof and bulkhead. This is available in many pack sizes, you may want to purchase a bulk pack to treat all the areas (arches, rear floor & roof) http://www.deadening.co.uk/products/silent-coat-2mm-mat-volume-pack 2nd stage: Apply Dodo Pro Barrier MLV over the top of the 2mm damping mat. This secondary treatment targets exterior airbourne noise that is not directly generated by the body panels. It is a barrier treatment to block unwanted noise intrusion into the cabin from outside. 100% coverage is recommended for the affected areas. Treat the boot and cabin floor to help block road, exhaust noise and tyre roar. These sheets are half a square metre each, we recommend having a measure up to determine the correct amount needed. http://www.deadening.co.uk/products/dodo-pro-barrier-mlv As a 2nd stage in the roof, we suggest using Silent Coat Absorber as mentioned at the top. Pretty helpful...I hope. I have gone ahead and ordered the recommended products. I'll have another go at the doors over the weekend (and maybe start on the boot area too) and report back. If the speaker rings if they arrive in time Ill stick them in too. might be overkill but having spent £200 on speakers I figure I should get the best out of them!

Me too

Awesome

Might be interested too.

Yeah - its a lot for a block of foam but I reckon any attempt I make to fabricate the same thing will end up with bleeding fingers, a lot of swearing and a total botch job. Lets see how things pan out when they arrive - fingers crossed.

http://www.soundconnectioninc.com/magento/index.php/6-fast-ring-kit.html Having seen set of these foam speaker rings online and a few favourable reviews I have just ordered a pair from the US. $25 +$15 shipping to UK. They can make a big difference....apparently. Will update the thread once delivered and fitted. Hoping they are the next best thing to door pods for sound quality installations.

Calling all traders - who has these in stock and how much delivered to central london?

If you have any more for £75 delivered Ill set a set.

So....got the drivers side door card off over the weekend to have a peek and found this: Sorry of the pic above doesnt work, it's my first time trying to post a pic. Inner door skin almost completely covered in Dynamat but not properly applied - i.e. big air pockets. No Dynamat around/through the speaker hole, just skimming over the top. Removing the speaker revealed no Dynamat on the exterior door skin behine the speaker either . I got to work by peeling some back and reapplying with a roller and tennis ball to ensure minimal air gaps. I trimmed some overlap Dynamat and used it to apply a 6 x 6 inch patch of to the are directly behind the speaker on the exterior door skin. might need to add more in the future but cant be arsed to remove the inner door skin, will apply as much as I can through the speaker hole. I also took to my speaker cover with a Dremmel (with limited success) as I read that this can improve things . After lots of mess with melted plastic I found I could remove the plastic sections inbetween the main spider web structure at the rear of the speaker cover using a sharp Stanley knife much more effectively. I would advise anyone wanting to do this mod to try the same. I managed to retain all the supporting structure leaving large air gaps for the audio to pass through unhindered. I then cut up some old black tights (don't ask), stretched over the speaker cover and had mum sew the overlap bits together behind the cover to keep it taught - trimming excess material afterwards. Cheers Mum! After all this I reassembled the door and installed the new speaker cover. I've got maybe a 5-10% improvement in mid range clarity but not enough. After some concentrated listening I realised that the muddy mids are due to the large air space between the door cards and the inner skin. Kicks and low bass seem fairly tight but high bass notes,vocals and midrange is resonating quite badly. So, current plans are: coat the inside of the door card with some sort of foam liner with a couple of big chunks of heavy foam stuck on strategically to act as baffles apply a foam ring (cut to correct profile) between the front of the speaker and the door card/speaker cover to try to minimse spill into the space between the rest of the door card and the inner door skin. will keep this thread updated with the results.

If there is room for one more, I'm in for 20mm + 25mm if that's both sets for £100
