as in title, I want to know if anyone had managed to make a sub box with 2 x 15" subs fit in the boot of their R33. I may be buying someones entire stereo system and just wanted to know if anyones done it successfully before. I have asked him for dimensions but he hasn't got back to me yet and I may be able to get a smaller or differnetly chaped box made up anyway

thanks guys / girls

lol! each to their own. i don't see how a bassy sound system would be horrible. I think 'horrible' is what my stock standard factory system sounds like.

why would you want such an over kill of a stereo in the first place? It would sound horrible

How is it bassy? Where will you be sitting or standing when you are listening to it?

Did you know that a 63Hz sound wave (roughly the frequency of a kick drum) takes about 4.8 metres to travel so if you are any closer than that to the speakers you wont hear it.

Hi there,

I have an R33 series 1 4door, now i think that they are the same size boot as the coupe. You will probbably have a lot of trouble mounting 2 x 15 subs in behind the rear seat unless you sacrafice a lot of boot space. If you don't use your boot it should be easy. However i think that 2 x 12s would be much better. The difference that you would actually hear between 12s and 15s is very minimal. I mean on paper the 15s go deeper and rattle the car appart more. I have had 2 15s and 2 12s in my old car and the 12s were much better because they have a higher respons and better sound. (my opinion.) If you get something like Rockford Fosgate our soundstream you really would only need one 12. They are insane. However i can understand the need for symetry i.e 2 subs.

You will ahve to consider what amp you are going to use aswell. You should always overpower speakers so that your amps dont work so hard. By overpower o dont mean run them into thr ground i mean supply them with more power than they need.

Thats just my 20 cents. I have gone through a few stereos, but like i said before each to their own.

:(

In a car you will hear it, because the sound bounces around the car. You are right though, but that is more the case in a hall or big room. A human ear cant hear below 20-25hz or higher than 15khz (some exeptions) so when you buy a speaker that is rated to below 25hz it will just shake everything :(

they will fit but you will have to have the box leaned back probably greater than 45 degrees.

in my 32 the box is at about this angle to fit under the boot lid for a 12 inch sub.

the bigger the sub the further it will have to be angled back.

i dont know how much higher a 33 boot is than a 32 boot though.

you will most likely have to custom make a box

thanks for all the comments guys.

I would not usually be looking at 2x15"s but it was just a good looking deal I came across. I have previously had either 2x 10" subs or 1 x 12" to give me the kick I needed. I still might lean towards the single quality 12" over 2 subs as I will need some boot space left for the groceries!

any recommendations on a killer 12"? I have heard the Alpine Type R are decent but I must admit to not having much knowledge of models / brands...

I have a Focal sub.......on rails(8") fitted to my gtr33.

Fits nicely in the corner without taking up much room.

You really for 2 * 15 Inch subs should look at a custom job.

Get a good installer to quote you.

You will take advantage of the dead space in the inside of the boot this way.

Cheers.

Give me a couple of days and I should have part of my guide up for making a fiberglass sub enclosure.

I'm using a 15inch that I had for my previous car because I could be bothered selling it and buying a new one. It sits in one of the back corners of the boot. Pretty much the area I masking taped off in the attached pic. Just repeat for the other side of the boot and your set. You'll lose access to your jack though if you don't make them removeable.

check out sondstream for amps and subs, they are disturbing

i think there are a few on ebay for a really good price $300-400

im getting a 4 chan picaso soon =)~~

MA audio have a few good subs too

hey guys i got 2 10" comp subs in the boot of my sky, like the dude with the taped up areas showing where boxes go i got some pics of mine, ignore the fact that i havent finished carpeting the necessary areas. i have also shifted my jack to behind the extinguisher u can see in the pics, there is a small door cut out, check it out. i could have put 12" in but i kept my 10" comp subs instead and they still rattle the tits off the skyline.

only 1 hint of advice is that u remove the old standard car amp, in boot next to battery mounted to underside of parcel shelf and redo all the stereo wires, clearer sound.

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
