as topic says

i was told by a mate after i bought it that it doesn't fit just by sitting it in the boot, you need to put it on an odd angle in the spare tyre tub...

wondering if anyone has got a trick way of fitting it nicely?

thanks

perhaps be more descriptive in your question next time and you might get a more descriptive answer.

is the box you want to fit a genuine alpine box or is the sub just in a wedge style pre fab box? if you can take a picture of it.

the pre fab wedge style boxes fit snugly under the parcel shelf in a 32.

and seems you have already bought the sub and box why dont you just put it in and see for yourself lol?

theres a reasonable height difference in the space under the parcel shelf in a 32 compaired to the hight available in a 33.how much clearance did you have between the top of the box and the underside of the boot lid?

hey mate i know wat you mean. I have a r32 with a genuine alpine 12" sub box and i lied it flat and it still doesnt fit. Had it sitting in the wheel well for a bit but gets chucked all over the place. Ended up making a wooden floor in the boot and bolted it down. Its the only way to do it if you wanna keep that box. Limits boot space but if you wanted boot space then why did you buy a skyline? :laugh:

someone told me skylines where great family cars and with the high petrol prices you would save heaps with the fuel economy that you would get from owning and driving a skyline. boy did i get fooled.

Ah... I get worse fuel consumption than anyone i know. Including 5.7L V8's and SR's etc... oh apart from GTR's lol they are REALLY bad

Cant you tell its not a family car by the size and fact that 'most' skylines have 2 doors?

Anyway let me know how you decide to mount the sub as i am interested in any other ideas ppl may have...

yeah boot space doesn't bother me, i just don't want it on some retarded angle and getting thrown everywhere as you said

today is the day i'm going to try and fit it so we'll see what happens, might go and change it for another brand one at JB if it doesn't fit

thanks matey

Make one yourself. A bit of MDF, some screws and some carpet.. Not hard.

I fitted a nice sized box under the parcel shelf with an angled back to use all the available volume against the back of the seat. Still gives me useable boot space. R32's don't really need a rear strut brace luckily.

So your just going to slap some wood together and hope for the best?

Its not that simple im afraid,subwoofer boxes NEED to be calculated and designed for the particular model sub you intend on using wit it.

Its like sticking a truck turbo on a little RB20,it will not perform well at all and in the end blow something up.

Im more then happy to design a box for you so you only have to follow my design and build it to spec.

I didn't say that, did bennett or mysterykid? Mine has the right volume for the sub that I had, for the response I wanted (god knows what it is cos that was a long time ago and I don't care that much about it).. just so happened to fit nicely under the parcel shelf with a bit of jiggery-pokery.

Jack88 - I already have the genuine box and i was going to measure the volume of it then make it about 10mm lower and adjust the width and depth accordingly to get the same volume. Do you really think this would affect the sound quality?

in answer to both of you, sealed boxes and generally fairly forgiving so a decrese in box volume by such a small amount wont really affect anything,you probly wont be able to hear the difference at all anyway. so you dont really have to adjust any dimentions.

yes thos type s's go pritty well in a sealed box too,for the money there an excelent sub.

Jack

EDIT are you planing to just built a whole new box or modify the alpine one? is the alpine one a sealed box or ported?

if its sealed box decresing the volume will just raise the tuning frequency a small amount which you probly wont be able to hear the difference.

id recomend building it equal in volume as the original one just to keep things the same,if your already modifying part of it you may as well do it all properly.

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
