I just bought a used 2007 Toyota FJ Cruiser with a AVIC-D3 installed. The FJ comes standard with 6 speakers, 2 tweeters in the dash, 2 in the doors and 2 in the ceiling; no subwoofer installed. I was playing around with the balance and fader and moved the fader all the way to the rear speakers (ceiling) and noticed there was very little sound coming from them compared to the fronts. Sound from the tweeters and door speakers sound great. The Rear SP setting is set to Full. Are there any other setting I should be looking for or do you think it was installed wrong?

Thanks,

Dave

I have a 2007 FJ with 8 speakers, AVIC-Z1. My rear speakers are very quiet also even when faded all the way back. They were the same before I put in the AVIC-Z1.
