Should I replace my rear speakers?



If you are wondering whether or not you should replace your rear speakers, there are a few things you need to know about your vehicles sound imaging before hand. And by imaging I mean how much of the sound you are hearing from the driver seat is actually coming from the rear speakers.

Generally speaking, if all the sound you are hearing from your audio system was represented as 100%, then the amount you are hearing from the rear speakers at the driver position only represents
about 30%. And that's if you are someone who keeps your fader settings in the middle at zero. Meaning you have them set to send half the sound to the front and half to the rear.  If you fade your sound more to the front then the rear (which I have found most people do), then what you hear from rear speakers is more like 20% of your overall sound.

Knowing this, it only makes sense to replace your rear speakers if:

1- they are blown and you hear any rattling or crackling sounds

2. You are already replacing the fronts and you want to replace the rears because you are going to amplify all of your speakers.

Above all if you are looking for a place to start, like when you are working with a limited budget, don't start with the rears as you will not get your best bang for your buck. And if you're trying to decide on where to spend the bulk of your speaker budget, do that on the fronts as well not the rears. 

Think about it, when you go to a concert they usually don't have highs and mids playing behind you. All of the sound comes from in front of you. So I usually recommend that if your rears are not blown, spend the money on better fronts. Or maybe think about just buying new front speakers and only amplify those.

For instance, let's say you already replaced your front speakers and are trying to decide if you want to replace the rear speakers. How about taking the money you were going to use to buy rear speakers and installation and use that to purchase an amp  for your fronts, thus boosting the volume and quality of the speakers that give you the most sound in your car. Most of the budget conscious people I recommend that idea to wind up thanking me later.

One of the few exceptions to this concept of replacing fronts before replacing rears is a Jeep Wrangler. Specifically the years that incorporated 4" x 6" speakers in the front and 5 1/4" or 6 1/2" ones in the upper sound bar. In this case, I do recommend starting with the rears if your budget is making you choose.
