I own a wagonr for past 4 years. The current audio setup is sony headunit with 4inch sony speakers in the front and 4 way sony coaxial speaker in the rear.
Of lately iam not satisifed with the sound and iam looking for upgrades and i wish to add a subwoofer and amplifier to my exisiting setup.
My budget is 15k, of course i can extend it by few thousands for a decent upgrade.
So please suggest me a upgrade for my current setup?
Do i need to modify my current setup or can i add on the sub and amp to exisiting setup?
