Hello All!!! I`m super excited to be part of this great forum. I`m looking forward to learn about car audio and such. I would love if some if you guys give me some recommendations on what kind of set-up to get. I have the factory setup on my 2005 Acura TSX I was looking to upgrade such system if possible at all. I was thinking of adding an amplifier and maybe a subwoofer to start. I currently have a $700 budget that can be used towards upgrading the audio on my car. Thanks for your help.
