Radio back speakers sound 'fill'?

Anybody have the back speakers for full sound rather than so called 'fill'?
I can't hear the back speakers in my DC unless I fade a lot to the back then lose sound quality.

 

What exactly are you asking. the speakers in the back, if you have a double cab would be for the passengers in the back, and would give you the benefit of "fill" sound. on an access cab, they have the same function, but are closer to you. it only makes sense that the speakers that are closer to you are going to be dominate, and you lose sound "quality" because they are smaller speakers. I do not know of anyone that drives around with the fad to the back becuase they like the sound coming from behind them. I guess mabe you could re word your question, and more people could help.

 

I guess what I'm trying to ask is how to bring the backs up to the front sound to level off sound.
The shop that installed my Kenwood,amp and speakers call the back speakers fill.
I'd like to have full sound all around.

 

this is what i found on "fill speakers"
http://www.termpro.com/articles/rearfill.html
they refer to the rear "fill speakers as satellite. and if you have home surround system with satellite speakers you know that they are for vocals and highs and some mid, no bass. i do not know if on the double cab calls the back speakers fill speakers, but i would not call them satellites. did they add any speakers other than the ones in the door? From what i can tell is fill speaker on a car are for a 5.1 system, they are not going to have alot of bass.

where did you get the term "fill" from, the amp the deck, the installer? the back speakers should be full range just like the font, unless you have a factory or after market sub, then there might be a freq cap on all the door speakers. I am not an expert on car audio, so i ma hoping someone else will chime in also. what do you mean by loosing sound quality, does it sound muffled, loose the bass reproduction, or overall "loudness". what head unit and amp model numbers do you have. it might be a simple as a cross over setting in the head unit. But depending on how long ago you had the install done, take it to the shop that did the install and explain what you are experiencing to them.

 

Your location on these speakers will make it hard to level out the sound. I suggest adjusting your rear amp setting higher to the rear channel as a possibility...
