Hey ive got a 1997 R33, and I want to change the stock speakers. I want a simple set up without subs which has atleast abit of decent bass. Ive thought about 6x9's but seems to be more trouble then its worth to do it right. So do any 6.5 inch speakers provide decent bass????

Sorry i'll elaborate im talking doors and parcel shelf. I dont want subs cause I enjoy my boot space. So im looking for a good combination that incorporates clarity and as much quality bass as possible.

Boston Accoustics Pro series....Not cheap but can handle a lot ! Top quality stuff.I watched oneday in store as a sales rep put a 12 inch sub on the floor facing up.He then put one foot on the cone of the sub...And then stood on it ! With shoes on...They really are a tough woofer...!

i can vouch for that. (see sig) boston pro series are fantastic. not cheap (around 1100 for the set) but well worth the money.

you can get 6.5" subs...

indeed. there is a product called the QMAX invissibass. its a 6.5" sub in its own ported enclosure.. goes well...

6.5 inch subs hmm interesting. Was having a read and cant find a pic of this invisibass but I dont think it would be able to be screwed into my parcel shelf because its already enclosed.

get a pair of kicker 8" subs on your parcel shelf, 6.5" splits in the front doors and fit some 6.5" splits either on the parcel shelf or in the rear quarter trims... had full sub enclosure in my boot and didn't get the full effect due to skylines havin the firewall in the rear

My suggestion would be is get some quality front splits. Amp them, deaden and seal the doors. Leave it at that. If thats not enough, then go to as mentioned above some 6.5inch subs. Get 2 put them in the rear stock speaker location.

That said there are some slimline subs, and with a good install you wont loose too much boot space. Not that R33s really have a boot to start with :(

Boston Pro's in the doors.THen I would put one 10 inch Boston Pro in the boot.Bostons really dont require a large enclosure.I was told they can be installed in like 1.5 cubic feet enclosure...? A good quality installer can make,install a box and trim it so it looks like it was designed there by factory and still have heaps of bootspace.As for fitting 2 subs..? What for ? these days subs handle so much power...one is all you need.I believe the Boston PRo 10 and 12 can handle in excess of 1000 watts...?? More than you will ever need

6.5" In front ... forget the rears. (unless you have too much money) ... #1 rule is get them installed properly. You can spend a few hundred dollars or a few thousand dollars. If there not installed right there going to sound shit!

6x9s does NOT equal bass.

If the 6.5" are installed well then they can produce surpising amounts of bass (providing the speakers aren't complete rubbish ie the factory ones :banana:).

As for the boot space...

Here's a GTR setup (small boot anyway) ... which produces stupid amounts of bass and doesn't eat up too much boot space.

I've currently running a rockford sub (which is pretty cheap wholesale and requires 0.8cuFeet sealed which is really small).

But getting back on topic

Here's what a really bassy 6.5" front door looks like:

There are some good articles on sound-deadening doors somewhere on the forum.

Nice install, I'm curious about the difference between going for the area where the battery is normally located and the side-of the boot as you have installed.

I'm assuming the bass would sound quite different depending on the install location?

Has anyone tested how the different installs sound?

I assume that the back of the car only fits a very small sub, 10inch?

Xizor, excellent point. I'm just thinking that if its placed behind that firewall facing the rear of the boot compared to sitting on the side of the car facing the other side of the boot.

Once has more room (across the boot), but will it sound different?

I'm curious if other people have tried both installs, I'm sure some of the shops have experimented.

For a decent sounding 6.5 that doesnt cost too much try an MTX TX6001. They are 6.5" components. You wouldnt need to run them of a smallish 2ch amp tho as ur head unit wont run them to even halfway close to their capacity for quality and sound volume. Or run those up front and run the coaxial version (not splits) at the rear - TDX6502, and run all four off a four channel amplifier. If you can fit a set of 6x9s in the rear you can get a lot of bass out of them, just look for something with a decent RMS power rating. Again, there is no point running these off a head unit. Depending on your budget, id look for a set of JBL GTO series speakers, ur looking at about $120-130 and sound great for the money. Nice and clear and deep. They do good splits too, for about $180. GTO937 are ur 6x9s, GTO607C are the splits.

Your best bet is to go into a store and listen to a few different ones. Dont worry about power ratings or shit like that, just shut ur eyes and flick through a few and pick what SOUNDS nice. Sounds gay, but you only buy em once, they are hidden once theyre installed, so who cares what brand and what they look like.

IMHO only! I know there are dfferent brands out there but theyre just a couple ive had really good remarks and feedback about, especially for the cash.

    • I would just put EBC back on the "I would not use their stuff" pile and move on.
    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
