tell if you have the rockford sound system or if you just have the regular. I have the touch screen but idk if i have it or not

 

Pop your trunk, if you dont see anything out of the ordinary, like maybe a sub, then you just have the regular sound system.

 

Well I dont think the Navi system is an option for the ES so it had to have been installed after?
In which case you might not have the RF system; but yeah... is the Subwoofer in the trunk? do you have tweeters in the A pillars? If so - it's the RF system... There's also more options in the audio settings such as "sub punch". I guess that's the best way to tell without tearing the car apart.

 

I have the navi system the factory one but not the sub. I do have the tweeters though. Whatever lol im fine with that i have subs on there way but my question is with all this factory system and then splitting into the speakers how can i add something to get more power to my speakers because there not that loud? I dont think i can run my amp and subs to it and an another for just the speakers

 

thats pretty much the way you have to do it. If you want powerful door speakers I would just say get a four channel amp for em.
