I've had my corolla for about a year now and i wanted to change the speakers or atleast add a sub to it. I know sometimes the stock speakers might not sound good with a sub so I was wondering if anyone knew of a good brand or company. Also looking to changing the deck of the stereo system but also wanting the AUX output to be visible.

my boyfriends a car audio specialist and he recommends infinity kappas for the speakers, pioneer deck for the radio, and rockford fosgate for the sub. the speakers will be 6 1/2 inch for the front and 6 x 9 in the rear. You can start by changing out the radio, then speakers then a sub. if you live by magic mountain in California he could help you out. if you have any other questions feel free to ask.
