HI Finally.....
Yes, your car has an amp to power the two subs in the rear parcel shelf.
Here is the thread that shows how to tweak it to get a better sound from it. Unlike our over-excitable american cousins, don't expect miracles, but it did sound better.

The amp is behind a bulkhead on the left side of the boot (when looking into the boot that is). Remove the top clip, pull the carpet back, and reach your arm in..... It is really easy - 1 minute job.
The reality is that the speakers are still pretty useless though - so as I said, dn't expect miracles.

Hi Gareth
I'll let you know soon....
I've decided to change the front and rear speakers, as well as the head unit, but for the moment I'm going to leave the parcel shelf subs, and the existing amp, as they are.
I want to replace the HU since I want a DVD unit (chosen the Alpine IVA-W200Ri). The next problem is that the standard speakers are only 2ohm, so with most replacement HU's you stand the risk of blowing them up as they are spec'd for 4ohm speakers.
So, I'm replacing the front and rears for quality 4ohm speakers (JL Audio). I'm using better quality front component sets than for the rear - but they are all good quality ones! This I'm hoping will give a significant increase in sound quality.
I'm hoping that the chage to quality speakers within the main body of the car will provide the necessary quality increase - and also probably a much tighter bass signal. I'm wondering it I might even disconnect the subs, depending on what I hear.
From what I understand, if you replace the existing parcel shelf subs with new good ones, it is highly likely that the existing amp will not be up to the job of driving the new subs speakers, so this will lead you to have to replace the amp as well.
I'm driven a lot by cost I must admit. I'm saving money by not replacing the rears/amp. I'm also saving money by driving the main speakers directly from the integral amp in the HU. Ideally I would have a separate amp to drive all the speakers - one day maybe!!
Anyway - hope that helps.
I'll be doing mine in the next two weeks. Got lots of boxes right now. I'll let you know more later if you are interested.
Cheers

Yes - you can replace the speakers only, leaving the standard HU in place. You will just notice it considerably quieter though on the same volume level as previous. From what I've read you can turn the HU back up enough to still make them loud, but you do get up towards the distortion area of the HU.
Many options - depends on what you want!

Hi Wormus,
In theory the amp is behind the bulkhead on the left hand side of the boot. It is located between the metal that the carpet mounts on and the outside skin of the car body. There is a gap near the back of the car that you can fit your hand round to fiddle with the amp settings.
You can't see the amp since it is hidden behind the metal....

You can turn off loudness by hitting the "LOC" (I don't know what it does the rest of the time...) button after pressing the volume knob in. Does anyone have a PDF manual for the stereo? I don't seem to have one. I followed the intructions on LS1GTO just now and it has made a bit of a difference.
I got slightly stumped when looking for the amp but it is there. The knob on the side facing the front of the car.

So it is! Thanks and God bless the Internet :-)
It is one of the options on the computer thing. When you turn the ignition on you get the up and down arrows on the display - if you hit one of those buttons while the dispaly shows this you will be able to scroll through a number of different config options, and somewhere in there you will find the thing you are looking for. From memory it has four levels and Off from which you can select.
