Installing new speakers

[ag9111]

Ohh they would have made life so much easier

[kouta666]

Hi all!
2. Any suggestions for what brand/type of speakers sound good?
I listen to heavy metal music (if that helps) also due to not wanting to cut bigger holes in door or anything, is there a brand of speaker that fits perfectly into the cavity without having to make anything to pack it out or make it fit. And not looking to spend hundreds of dollars!

Thanks

Hey mate, unfortunately even with spending the bare minimum, it will cost hundreds of dollars. It all adds up. I've just finished my upgrade and the difference is chalk and cheese. I get thumping bass with no vibrations now. I listen to Darkstep and all forms of Metal. It took a bit getting the levels all right.

All items I purchased on sale:

New Sony media receiver - $90 (JB Hifi)
Fusion AS1080 subwoofer - $170 (Autobarn)
Sony 6.5" 3-Way (front) - $60 (Supacheap)
Kenwood 6.5" 2-Way (rear) - $50 (Supacheap)
Dynamat and Mongoose Sound deadening in 4 doors (70% of the inner door) - $70 (AutoOne)

Total = $440
Plus many hours in labour

....but I did it in stages.....1. Head unit. 2. Subwoofer 3. Speakers 4. Sound deadening

Any 6.5" speaker will fit perfectly into the existing speaker housing. Just cut out the old speaker first. I just used a dremal with a cutting disc. Then hit it with a hammer and it pops out. Screwed the new speaker to it. Fits nice on the existing foam ring.

Here's some pics of the front door (completed) and the rear door (before and after)
Hope that helps. Just do it. It's great fun and you learn along the way. Like how not to break the trim lugs and where to buy replacement ones

Sound deadening in 4 doors (70% of the inner door)

Was there a reason why you only covered 70%?

[Naff]

70% better?

[Cowboy Dave]

Aren't you supposed to do inside the door too? I hope so, because that's what I, I mean what a mate of mine did and I hate to find out I, I mean he, got it all wrong

[mad992]

Great piccys Kouta

[NowForThe5th]

Worst case scenario is that he got 30% wrong, CD. For him that's quite possibly an achievement. Especially if they actually work.

I was waiting for a nice technical explanation, like kouta had calculated the size and shape for volume of the doors and the 30% left open would work like a port in a speaker box.

[kouta666]

haha....Only did 70% due to the cost. If I had more money then sure, all the doors (both layers) and also covering all the holes would be ideal. Doing the inside of the door would be a bitch to do too. I did do directly behind each speaker though.

I mainly wanted to stop the doors rattling from the bass.

[NowForThe5th]

Ah. Thanks kouta.

Since I do a bit of bodywork I find it interesting to see what manufacturers do. Sometimes it's just a small pad, other times a strip of (usually) a bituminous filled dampener. The idea is just to stop resonance - it's unlikely that it actually improves the sound other than removing resonances which, does actually improve the sound, without actually improving the sound.

Gawd that was an awful sentence, but you know what I mean, I hope.

[explorer.dave]

^ about 70%

[Cowboy Dave]

Not even 30% understood here.

[Dellian]

Firstly I want to thank Kegsy and BosvarQ for their help even though I went a different route with my speaker install.

I got four 6.5" Sony speakers at Autobarn for $100. Didn't want anything to fancy considering the young girls been for a long bath before.

I used a jigsaw with an old blade to cut out the original speakers. Make sure you don't cut the door adapters! The 6.5" speakers fit perfectly into the spacers and were secured with the screws supplied.

Drivers side negative is blue and positive is yellow.
Passenger side negative is black and positive is yellow.
Rear seats negative is yellow and positive is white.

Got them all installed in a few hours.

Has anyone replaced the 2009 'ish Power Sound speakers ?

Has an amplifier under the passenger seat.

As I am too lazy to take the door skins off just to look at them, asking here is easier

My factory ones still seem ok, but if they can be improved......

[NowForThe5th]

I think Snowie had those and replaced them, Craig. Maybe also ask CD.

[Cowboy Dave]

I suspect mine were power sound speakers. I had an amp and there is some sort of sticker so probly.

They were shite compared to what I put in.

You don't need to upgrade to alpine or anything. Just grab something halfway decent at Supercheap and you should notice the difference I reckon.

[salt36]

Cool, thanks.

I will upgrade them, as I mentioned the factory are not bad but if I can crank it higher volume with less distortion then will be worth the money.

[NowForThe5th]

You don't need to upgrade to alpine or anything. Just grab something halfway decent at Supercheap and you should notice the difference I reckon.

Agree. It was the thing I noticed with the Triton - that I could crank more volume without distortion. In the Paj the speakers were much better quality but there I gained clarity and the better quality tweeters moved the sound stage up, quite noticeably.

I now have Sony splits in the front and Panasonic 3-way in the rear. Much better.

I had to rotate my speakers as they where earthing out on the door. I've had this issue intermittently since last years outback trip running the corrugations. It would also seem to happen on hot days. I'd originally thought the wiring was earthing but that was all good.
Just a heads up in case anybody else strikes this issue.

[Kegsy]

Ah. Thanks kouta.

Gawd that was an awful sentence, but you know what I mean, I hope.

Quite correct.
Sound deadening doesn't improve your speaker, rather it adds mass to the panel(s) which in turn reduces resonant sound waves letting your hear accurately what the driver is playing.

Plenty of weird and wonderfull deadening techniques are out there in the comp cars. Brush on bitumen paint, deadener sheets, I've even seen concrete used in some panels to stop vibrations

Best upgrade to any sound system is deadening. This is always the go to item.

And CD, rest easy mate, the outer door skin is the most important part of the deadener install. Its the lightest and weakest panel. IE: moves / resonates the most.

Great neat build there and thanks for the info. I've learnt heaps here.
One question that I have is in regard to the under passenger seat amp of my glxr Trion 09. Why so many wires? There are about 27 wires coming from it. Last tome I did anything like swap my speakers over my amp had 4 channels in, 4 out one +ve one -ve and earth. 19 wires in total.
Since I'm going to be putting splits back in with a crossover I was wondering if the stock amp acts as a crossover also.
Has anyone come across any issues in relation to this?
Thanks.

[Cowboy Dave]

Yes the amp acts as a crossover. sort of.

In that it takes 4 channels in and puts 6 out.

So 4 in is 8 wires.
6 out is 12 wires.

That's 20 so far.

At least 2 earths from memory.

Then you've got a positive trigger from the head unit.

23 so far?

Fused 12v+ makes 24.

Can't remember the other 3. Maybe ignition or accessory positive?

I've got it all written down somewhere from when I bypassed mine.

[brentus]

Man that sounds complicated. Thanks for the response.
If you happen to stumble across it I'd very much appreciate it if you flicked it over to me.
By the sounds of things to upgrade the speakers I'll need to upgrade or bypass the amp.
I think I need to speak to the car stereo mob again and see how I'd go without one. New decent quality head unit should go ok.
Thanks again

[Cowboy Dave]

It's actually not too bad to bypass. You ignore the wires to the tweeters, tape up the negatives and the positives and then you're basically just matching up the 8 inputs with the 8 outputs.

[Four of us]

I'm thinking of installing some split speakers in my GLX. The question is does anyone know if any brand of splits will fit in the lower corner of the door panel where I assume they fit in the GLXR and are they easy to install?

Why would you by-pass the stock amp ?

I would have thought it would add grunt to the sound ?
