Does anyone know what size teh facotry sub is and what aftermarket ones would fit to replace it.

and where is the factory ampf or it?

Cheers

Looks like a 12 from here (http://www.te.co.nz/te-motors/Cars/Mitsubishi/Diamante/141-1-100_ad-3223250.htm), but I'd be more concerned about wattage!

I don't think cars for the Aussie market have a factory sub.

However, there is a 6.5"-ish pressing in the parcel shelf, between the middle baby seat anchor and the left speaker.

There is no cutout for a speaker in it, and there is a support bracket welded across the centre. My plan is to drill out the welds, remove the bracket, and mount my GPS reciever there.

prior to TJ there was a removable plate

Fairlane/premium sound range falcons did, from the Ef onward i believe, and the ralliarts as well

I just meant Magnas/Veradas... There are quite a few cars from other manufacturers that have them.

His car is a NZ spec KH Diamante.

I do believe that this will render the car unroadworthy as you'd then be modifying the parcel shelf. Pre TJ i'm pretty sure comes with a screwed in plate.

The bracket isn't a structural part.

It's an inverted U shape, just to hold that area of parcel shelf up.

Edit: Just spoke to my mechanic (who is a very picky Licenced Vehicle Tester). Law states that no structural metal can be removed from the parcel shelf. Drilling out spot welds from holes that were already there doesn't count, neither does removing a bracket that is not an integral part of the structure of the parcel shelf itself.

You're going to have to use a free-air sub anyway, which will probably sound no where near as good as a sub in a well built enclosure.

The only reason you would consider doing this is for show rather than function.

The whole idea of bass firing directly into the cabin space is a misconception too as bass in non-directional.

Having said that however, in a boot, sub position is important to avoid sound wave cancellation as the enclosed space of the boot will act as another enclosure.

everyone knows that a boxed enclosure will always be better than a free air install.

however, free air is better than just some fronts and 6x9's.

I need the full use of my boot space on a daily basis so a box is not an option.

Just measure the hole and it is about 200mm so about 8", it has 4 screws holding the cover plate down.

Now to take the rear shelf off to get to it.

In the aussie spec cars thats only actually a removable plate on the TE/KE. TF/KF on had the mould but nothing was removable. Its an 8" opening. I was going to use it once upon a time, but the difficulty of finding a free air sub which was slim enough to not affect anything under the shelf was too great for the benefits.

Yeah same sort of thoughts now, just going to find a 10" that only needs a small sealed enclosure.

Another option is a Bass Extension Kit in the rear, which are essentially 2 small subs on your parcel shelf in place of your rear speakers. Digital Designs DDW6.5 (http://www.ddaudio.com/dd/caraudio/woofers.asp?series=W6.5) (RRP$249ea), and Focal 165 KBE (http://www.focalaustralia.com.au/k2_power.html#165kbe) (RRP$669 a pair) are two off the top of my head. I'm personally putting the Focal's in mine as I need my boot space too :D

Exp option though..

Could something be done with the armrest opening? Maybe MDF cut to fit behind the seats and have the sub mounted to the mdf firing though the armest hole? I've had 2 8inch subs on the parcel shelf in the past with my TP ... to be honest wasn't much chop. You'd be better off getting a set of 6x9 or 7x10 speakers on a good amp.

is there much to be gained from amped 6x9's?

Yeah, you'll notice quite a difference. Wouldn't bother amping cheap 6x9"s though, get some good ones. DD make some fantastic 6x9"s for $179, Soundstream's SST6.9 (I think) are great too but they're closer to $300.

Definately. Generally speaking your average head unit will only output 15-25w of clean RMS to the speakers. By adding an amp you can increase this to 35w upwards.

As Lugo said a good set though .. Depending on your budget a good set can be as cheap as Pioneer 3 ways. Make sure you go and have a listen to them in store though (without a sub going) and pick the ones that sound the best to you.

You'll be surprised how small of a box you can get away with when using a 10" sub.

If you pack it with audio spec stuffing, you can 'fool' the subwoofer into thinking its in a larger enclosure - up to 30% bigger!

I put a 10" in my sisters Rav 4 last week. She didn't want a large enclosure at all! The box ended up being about 35cm x 35cm x 20cm. Which is about 0.8 cubic feet. However, i also put stuffing in it and it plays very nicely.

Very small and unintrusive.

The Amp is mounted under the passenger seat. If she ever wants to remove the box, its a matter of clipping off two wires and presto - boot space is back!

I got some alpine type s rated at 50w ,and my amp is the jaycar 2x150.

So how is the system setup at to moment? Apline head unit, jaycar amp ... what speakers do you have and what is the amp driving?

Alpine
9833 hu
type s coax sps17c2 front
type s 6X9 sps69c3 rear

all running off the hu

amp to be installed

after more bass

Get the amp installed to the rear speakers and use the crossover settings in the head unit to control the bass going to the front speakers. You should get a cleaner, louder sound and the 6x9's will have more noticeable bass. (providing your unit is installed properly and all speakers in phase with decent speaker wire)

Fronts are xover on the hu at 80hz, rears get full range.

i will hold on the sub to see what the 6x9 can do.
