the idea behind facing subs backwards is all to do with "loading." it is possible to get up to a 3 db gain just by loading the sub off say the hatch in a hatch back. the idea is the subs and the car work together basically creating noise. the problem with loading a sub backwards in a sedan is, if i set the picture, in a hatch, the waves hit the back of the car, then basically bounce off a place in the roof, then into the front of the vehicle. the problem with loading it in a sedan, it bounces of the rear of th boot, to the boot lid, then basically back into the subs where it came from, causing cancellation. it works but is not as efficent. a way i have found that has worked time and time again is to face the subs towards the front of the vehicle, making the box so it seals the boot from the cabin, making the subs part of the cabin, and porting the box into the cab. this makes the cab smaller in terms of sound pressure level (SPL) and there is no problem with cancellation. it is hard to explain what i am rambleing on about over the internet, but i hope it helps in some respect. Take care all and happy "stereoing"

How much do people know about fibreglassing? or even just building replacement walls for the boot? The stock stuff on mine is a little hacked on one side, and seeing as i am putting in sub/amps in soon, thought it might be a good time to investigate getting in replaced. Do people get this kinda thing done at the audio shop? any idea on costs and details? It seems too time consuming/painful to try and measure it up myself. call me lazy

Damn thats a pretty nice website - love all the install's pics. Unfortunately i am in adelaide - bit far to go for some custom work. Is there anyway to get an idea of the cost of some of those installs? Also, anyone know of a equally impressive seeming place in SA?

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.

      Yes they do. For some maybe. But for those used the most by abusers, ie Skylines, the numbers are known. The stock eyebrow height for R32/3 Skylines is about 365/375mm or thereabouts. The minimum such heights are recorded in adjacent columns in the database.

      Hmmm, interesting. Makes me wonder whether there is bias as well. It's the cheapest fuel, so it is used for all kinds of ill-maintained shitboxes which are bound to have issues regardless. Nicer cars tend to require higher octane rated fuel and can't use it anyway. FWIW, the official NSW E10 facts page is decent.
