I need some help with speakers
 

So I'm very new to car audio. The latest thing I've done my car is hookup a 10" 150w RMS sub and an amp with the same RMS. I want to also change out the four door speakers. The front needs 6x9 and the rear needs 6-3/4". I am looking at Kicker speakers that look nice and will match my sub brand lol. My main question is if these speakers will increase the bass from the stock speakers or if it will just stay the same. I just want them to be able to handle a bit more volume and give a better kick that you can feel. I really don't want to have to buy another amp, they are pretty expensive for me, and hooking up one amp to one sub took me 6 hours to figure out. I can't imagine how connecting four to one amp would be. If anyone can give me some advice I would really appreciate it
