Total Newbie - Speaker dimensions?

Hi,

I'm a bit confused, and though this'll probably seem dumb to most of you,
I'd appreciate some advice!

http://homepage.ntlworld.com/mick.knaggs/spk.jpg

This is one of the stock speakers I've just pulled out of the shelf, can
somone tell me what size speaker I should be looking for to replace these
with some better quality ones?
Just a bit confused as to 'cut-out' and actual speaker dimensions..


I'd set my sights on these, but really not sure of sizes/capability.

I have a JVC KD G701 which reports 50W X 4..
I'm guessing I should be concentrating on the input wattage of a speaker,
rather than the peak?

All this RMS/max power/max input..!

Also, any links to decent car audio sites would be good.


Cheers for any help,


M

*cough*
Daewoo Nexia ( on a P ) 1.5 GLi

:-)

Worth mentioning I have some Clarion in there now, the JVC was way too much
for the stock speakers.
It's just these damn dimensions I'm getting confused with.

Presumably a saloon if they're standard fitment on the rear shelf?

If so, they're a standard 160mm driver. Sometimes also known as 6
inch, but I'd use the metric measurement, as the Japanese and
Americans can't seem to agree on how big 6 inches is....

Hi Jon, thanks again for your reply.
Yeah sorry, it is a saloon - shoulda said.
(First saloon I've ever had - a pain to have to sit in the boot messing with
the speaker connections rather than dropping the seats!)

I presume you saw the jpeg I posted a link for Jon?
I'm just trying to decide out of curiosity where the 160mm is taken - best I
can do is from the far left to the far right of the screw holes..?

Anyway, thanks for your help - at least now I know what size speakers to
buy.

I've actually just taken another look at your image, and I can't quite
tell, but it looks like it might have 4 fixing screws? If so, then
it's not going to be a 160mm (which usually have 3), but more likely a
165mm, which isn't especially surprising as the car's effectively a
Vauxhall Belmont (which used 165mm eurosize)

Rather than worrying about the speaker size, I'd measure the mounting
hole. A 130mm mounting hole equates to a 160cm (usually Japanese and
American) driver, and 150mm equates to a 165mm (eurosize) speaker.

Sony's database lists 160mm speakers for the car, but a 153mm cutout,
so I'm not thinking they've probably got things wrong!

Yes, that's right.

Ok, so 165mm (6.5") is probably the size I'm looking for.

Ah right..
Well, that gives me even more info, and I'll keep hold of your post and
refer to it when I pop the grilles off next.

Thanks muchly for your time Jon - much appreciated.
