hello all I am working on a rc hobby trailer.. that will have a pioneer head unit in it... so I have the Pionnerr Head unit with 2 6.5 pioneer speakre up front.. and then on a dual 400 amp I have two Pioneer 2 way 6x9 speakers.. if im wrong correct me been awhile since i did any installs like 10 years.. but with the 2way speakers all I will get is mids and base in the back right? so if i switch to a pioneer 3way or 4 way 6x9 i will get it all in the back correct....
