Ive got a base model 2012 GT. Its got no shaker system and no steering wheel controls. Its automatic. Thats it. Ive got two 10s in a ported box with an amp. They work. I want to install those, change out the speakers in my car, and possibly get a head unit. I need help finding what would be the least amount of headache with installing those speakers inside the car, for the cheapest price. I always play my music very loud so i need something that wont need its own separate amp but wont blow if i play loud *** music with the bass up. Ill probably do the inside speakers before i do the subs, and probably do the subs and Head unit together. If i can get some opinions on the best speakers with the easiest install and cheapest price for the best quality sound i would really appreciate that. Im not too savvy with it comes to audio stuff, but i realize i can't get everything i want.
