Looks great, good on you for saving up the cash too
If your upgrading to premium sound, I'd probably spend the money on better speakers / head unit / subwoofer and amp if I was you.
I have the premium setup in my car, hooked up to a new sub / amp.. all stock speakers apart from the sub... it sounds pretty decent but it really needs more powerful speakers, head unit needs more tune-ability (midrange, subwoofer would be good - there is wayy too much mid range) and the head unit needs more power.. but the speakers do sound pretty good, they just don't handle much power... I added the AUX in, its alright for now.. just saving up some money and I'll eventually upgrade it.
