Thanks Mike for the advice on the Temp. Can anyone inform me the best way (read easy) to upgrade Audio in KL Verada...are we talking head unit, amp, I'm thinking spend $500 - $700 or is it simply not worth it.
Apologies if I am rehashing stuff already answered prior.

Well, Verada's have a premium sound as it is, and even tho I overhauled mine, i still think to this day it's one of the best sounding stock systems around. Aside from that, it depends what kind of audio do you want? If you want something loud and bassy you could prob get away with a new HU amp and sub and keep your current speakers. Or you could put it all into your front end and get a great quality sound, you just wont have everyone out the front of the local shopping center looking at you as you drive past :P
It's not hard to spend lots in car audio, as i found out the hard way lol I started off with a 1000 budget and ended up getting over 2.5k worth of gear *sigh*
Anyway, from what I found, best thing to do is go have a listen at shops, depending where you are, but if you're in melb check out Garys Car Radio, Stylyn Car Audio, Autobarn and JB.

Add a sub if you are after bass, change the head unit, you may be able to sell it here if you like. The front speakers arent actually that bad once you cross them over. Add new 6x9 and you end up with something not altogether awful.

Focus on front splits and a new headunit and work your way back from there.
Most important aspect of any car audio is front splits. This is where 75% of your frequency range comes from.
