stereo upgrade
Discussion
It will work but you will draw alot of power through the head unit and it may cut out on overtemp... or blow the amp if you get carried away with the volume.
TBH the standard speakers are your holding factor so these really need to be changed to improve the sound!
Oh and BTW - its not just a simple swap for another double din unit! you will need the surround and a PAC audio addaptor lead which needs modifying or at least programing.
Im just in the process of changing all mone out, have put 4ohm 250 watt speakers all around and larger subs in the rear sides, 3 amps mounted in the boot drive this lot, just deciding which head unit to purchase.

just had a good chat with RMD audio and they have quoted to replace the speakers with a proper brand all inclusive £300ish so not too bad
I know i need to buy an adaptor for the double din, with regard to the pac audio adaptor im not sure this will work as im likely to be buying a chinese all in nav, stereo jobby so may well lose sterring wheel control, but thats not a big issue for me to be honest. If it will work then great but not sure how

Really tempted to get mine replaced. I wonder how much they'll charge for a complete system inc amps HU etc? They've done a few Monaros so at least they probably know what they're doing.

i understand the speakers are 2 ohm are they not and a standard stereo runs 4 ohms?
Are you sure the standard speakers are 2 ohm? I would be surprised if this was the case because most standard head units and speakers I have seen are 4 ohm systems. Usually, if you want to run an amp at 2 ohm you have to make sure the amp itself is 2 ohm stable. This is not usually the case for a standard head unit.
Also, most standard fit speakers are really poor quality, even ones that are reportedly from a manufactuer such as BOSE. The cones are a dead giveaway, if they are paper, get rid. I checked out the speakers in a Mazda 6 with the BOSE system and even those speakers were Pi$$ poor, crappy plastic cones and tiny driver (magnet).
By spending as little as £60 on a pair of 160mm 2ways you can make massive improvements in the sound. I would suggest that as a first step, or a new head unit and speakers. If you change the head unit and not the speakers, the sound could still be poor due to the shoddy speakers.

whole system is deffo 2 ohm

OK, the most obvious advice would be the match the resistance of the new head unit you want with an equivalent pair of speakers. There are 2 ohm stable HU's out there. Or treat yourself to a new 4 ohm HU and speakers, job done and you have nothing to worry about.
However, if you did run 2 ohm speakers on a 4 ohm HU the there is the risk of damaging the amp. But, that is not to say you would fry the amp, it is possible and perhaps not worth the risk. Basically, if your amp is 50w at 4 ohm, it would need 100w to run a 2 ohm load equally.
It may be worth thinking about how loud you want the system to go. If you dont usually crank it up you could be ok with the standard speakers. (sorry this doesnt help much)
