So that's why my bass was stuffed...

[moondog]

I know I shouldn't have expected too much bass out of the factory speakers, but still... When I got the car it sounded fairly good, then the bass left, to be replaced by a btbtbtthththt sort of noise

Bought some new speakers at Autosalon cos it seemed like a good idea at the time, then everyone tells me you can't just throw 6x9s in the back of Skylines, so they sit in the box in my garage for many many months.

Well I finally decided bugger it, I'm gonna have a go

Here's why the bass was buggered:





And yes, My Pioneer 6x9s do indeed fit in the back of my Skyline:





I is much happier now

Don't you love expensive cars with cheap paper cone speakers!

I did all 10 speakers on a 928 porsche the other day that were in far worse condition. The foam seal between the cone and the frame had come away completly on 8 of the 10, and all 10 speakers are in a custom shaped surround to fit the 928 interior.
Forunatly theres a shop in West Auckland (I cant remember whats it's called) that reattachs the cones to the frames. But for a car that cost $200,000 you would expect it to have better speakers.

The door speakers on my Civic, and the Prelude were both exactly the same, infact I have no seen a paper cone speaker last more than about 8-10 years in a car, but I know of home speakers that are over 20 years old are only now starting to break down.

Your old ones are not really that bad, at least the main cone is still attached.


So how much did you have to cut out of the back of the car to make the 6X9s fit?
(nice choice of speaker by the way)

[SHANE W]

My speakers developed a nasty rattling noise. when i pulled them out i tured them upside down and half the cone fell out!
Got some decent componants now so it much better

[R33]

Err...can those thingy in the pics make my Skyline go any faster? If so, how much are they nad where can I get them?

[Gtr2.7L]

Are the pioneers "bolt In"?

No.....I'm really asking! I'd like to do the same thing

[moondog]

They're not so much "bolt-in" as "stuff them in the back and squash them on when I put the parcel tray back in" You need to take out the rear seats, and get the parcel tray out - the speakers are attached to it, so you need to unscrew them. I used the template that you cut out of the box the Pioneers came in, and cut new holes out of the parcel tray. There are gaps left, but I just arranged it to make sure the screw holes weren't over gaps. Then it was the simple matter of screwing the new speakers onto the parcel tray, and the not-quite-so-simple matter of levering it all back in, and soldering the speaker wires on. I actually had to add an additional bit of wire for the passenger side speaker, as the connector bits are in a totally different place (although I spose if I had checked it out beforehand, I could have simply attached the speakers physically the other way around....

In answer to your question Moppie, I didn't cut anything out. Even if I had cut some metal for them to sit in better, there's no room really before the magnet on the passenger side would be hitting the battery - conveniently placed just below it. What I will be doing at some point is doing a new parcel tray with some actual mounts to hold the speakers, but what I've got will do for now.

And yeah, I like the Pioneers. I bought them simply because of the price for a brand i recognised but I've since had a listen at Proclass in Auckland to a bunch of different front/rear speaker combinations. I'm sold on VDO Dayton 5"splits in the front, but the Pioneer 6x9s sounded better for rear speakers than the VDO Dayton 6x9s, so I'll stick with them.

Moppie, Moppie, Moppie when are you going to learn mate. It is hard to think you know more than the people that actually are into Skylines and do own them.

Raf I've got 6x9's in my R, Pioneer also and love them! I made up a small raiser block so they are lifted enough so the metal case clears the small factory hole. It was as straight screw in job. I've seen so many rough barbarians cut the rear shelf to fit them and laughed.

Where in this thread have I done the above?

I merely pointed out a common problem with about 90% of the worlds cars, factory fitted speakers are crap, and its a problem that even $230,000 super car owners have to put up with.


I then asked Raf a question which he kindly answered, and made a comment about Pioneer audio quality, a brand Iv been useing for 8 years now, and will only go away from if its removed from the NZ market. (he did have to cut stuff out of the back of the car, or the parcel tray at least, but Iv seen many 6x9 installs where at least some sheet metal from under the parcel tray has to be cut, Im impressed that you can fit them into a Skyline with out doing any cutting)


And its and even more relevnt Q. and comment as a friend just bought an R33 GTS on monday, and when showing it off last night commented that it still had the factory speakers in it, and they sound about as stuffed as Rafs. If I end up fitting new speakers I want to know all I can about whats involved, as Iv never liked cutting sheet metal out of cars, something that often has to be done to fit oval speakers into round holes.

The best way to mount 6x9's is with a riser block. If you cut that back tray at ALL and the WOF catches it he will fail the car for sturctural! Once that happens it will cost you a tonne of money to get it fixed so you can get another warrent. That topic has been discussed to death else where.

The factory speakers for how old the car was, were damn good back then. Clarian speakers with Kenwood or Pioneer stereos though not badged as such. Even the factory amp under the tray is clarian. Last time I looked back in 96 or earlier they were very good. Compared to today's standards they are not.

Theres no such thing as a good paper cone speaker, especialy in 96.

Way back at the end start of 95 I managed to pick up a set of Pioneer 6inchs with poly cones, they were nothing particlary new back then, but are the same speakers I now have in the front of the prelude, infact the orginal 4inchs I got for my first car in 94 had poly cones.

Of course in Nissans defence the car was only built for the Japanese market where it wasnt expected to be around any longer than 5yrs, which is about the limit for a paper cone speaker, but not longer enough to justifie the expense of a poly cone.



And Im sorry, but how is cutting a piece of custom wood going to affect the cars structural integeraty? Clearly if you cut the steel frame underneath it will, and its the reason I dont like doing it, but the tray the speakers are mounted into isnt exatly structural.

Moppie you really need to lay off the piss aye. Re-read what I posted. If you cut that back tray at ALL and the WOF catches it he will fail the car for sturctural! I made no mention of cutting a block of wood, would effect structural anything. The hole is round 6.5 inches to be exact, and 6x9 speakers won't just drop in properly. By using a riser block you are able to use the 4 factory screw holes in the tray, by screwing the block to the tray. The 6x9's then get attached to the top of the riser block.
Like it or not, believe it or not that parcel tray is considered by NZ Testing Stations as a structural part of the car. Why? I have no bloody idea.

Now as far as your other comment about the quality of the speakers used FFS what auto manufacture uses poly cones as a factory installed item besides your upper top end luxury cars? The Skyline was never considered a luxury car dammit, so why waste money and put in something that has no bearing or effect on performance. When I bought my skylines I certainly didn't give a toss about the damn speakers, and 99.9% of Skyline owners don't even consider what it has in it for audio gear to start with. If that is all you're interested in go and by a honda and be happy thumping around in your little trolly.

Hahah no worries. I had a chat with Raf and he metioned something that made more sense that all of this. I believe you were thinking of the cardboard/carpet cover on top of the metal shelf, where I was refering to the metal shelf itself.

Damn Kiwi/Americans can't get on the same page sometimes aye

I was wondering why you getting so shitty!!
I keep forgeting your used to be a silly yank.

The parcel shelf is the bit of custom wood, or cardbourd that sits on top, that is normaly what the speakers in most are cars mounted into, and if I read rafs post correctly its exactly what he did with his new ones.
If you fail a WOF for cutting it you got screwed.

The Metal frame work underneath is a structural part of the car, but in some cases e.g. the R33 it also has speaker mounts in it. Often these are to small to take an aftermarket speaker, but of course cutting them can weaken the whole back of the car, which should cause you to fail a WOF.
However some cars (my old Triumph, and old Datsun for example) had provisions in that metal frame work to have extra cut out to fit a larger speaker, basicly the factory had been to cheap to cut the hole themselves, but had left stamping marks for it to be cut by the speaker installer, and cutting it should not void the WOF.

[RazorGTR]

Actually according to the LTSA Testing Station dudes on Rosebank road if you cut the metal shelf at all they will ping you for it. About the only thing you can do is drill a few small holes like for screws but you can't go overboard either. Their strict but fair if that makes sense in New Zealand.

Raf came over yesterday and I showed him what I had done. Damn I really need to sus ot a camera aye. it is really impressive and I was quite happy with the job when done.
