I'm new to the car audio world as I just started gaining interest in putting an upgraded system into my new vechile, so I have a couple questions.

I have a 2014 Ford Edge.
1. I'm curious what the best opinion to go is, 2 10s, 12s ect. Replace all my stock speakers?
2. Is there any subs and amps that's can fit under a SUV seat, would a truck ones fit.

Thank you!

If you get your car audio sound quality is maximized. should replace the standard speakers, subwoofer amplifier subwoofer should use, because it can practically pengemudik placed under the seat, and the car head unit should be replaced with a good quality product. as to determine the quality of the sound, the main source of the head unit.
