Upgraded speakers and it sounds the same.. help?

so i took out the stock speakers of my 2015 tacoma, and installed JBL GTO629 in the rear and JBL GTO939 in the front, surprisingly it sounds damn near the same. I want to get more power out of the speakers but want the thing to look entirely stock. whats a good amp i can run to these speakers and do they make stock plugs for the stock head unit? i got the screen on mine.

 

Kicker 200.4 is pretty commonly used around here. I chucked a 180.4 in.

You can fit the amp in the dash (guide referenced in my post linked above) or follow what I did the second time around and remote mount the amp under the driver seat. It would require some seat spacers for the rear legs, but I had those already and the 180.4 and 500.1 fit easily.

 

There is some compression (removal) adjustments that can be made in the head unit. Makes a difference.

 

Any more info? I wasn’t aware of this.
