? 2005 Mazda3- Crappy Audio: Should replace deck and/or speakers

[blondee_yvr]

Your radio does have a "volume leveler to increase the sound of the back speakers"! Its called a fader!

I dunno if it was posted here or in another forum, but the sound level in the rear is a lot less than in the front, even with the use of the fader,it's especially quite poor with my MTX's in the rear. I had much better response from the rear stock speakers.
