ramman949 Posted October 30, 2006 Report Share Posted October 30, 2006 Hey all, I recently got the AVIC-D2 and used a wiring harness for clean install. I also have a subwoofer hooked up into the SUB pre-outs. My issue is; that my rear speakers (not subs) are very quiet compaired to my fronts. My front speakers seem almost double in sound if I leave the fader at "0". I have to move my fader to +5 on the rear to ballance them out. My stock radio, all speakers were equal. Why is this? Also, I read the manual about how the rear speakers can be changed to FULL or Subwoofer and I have them set to FULL. If I changed that setting, I loose front and back fader and the subwoofer icon changes to non fader button. Is it normal for this unit to have so much more power to the front speakers comparied to the rear (not subs)? Help! and thank you! PS: 06 STI, using a wiring harness, soldered wires, all colored wires match, sound is clean, fader works correctly, just the rears are muffled compaired to fronts volume wise. Also the rears sound like NO highs are going though them. They sound FLAT. Quote Link to post Share on other sites
jimmy303 Posted October 30, 2006 Report Share Posted October 30, 2006 With the unit turned off, but the car on, push in the joystick, go to 'Initial', select rear speakers, and make sure they are set to 'full', not 'sub'. Quote Link to post Share on other sites
ramman949 Posted October 30, 2006 Author Report Share Posted October 30, 2006 I did and its set to FULL. Still the same. Quote Link to post Share on other sites
jimmy303 Posted October 30, 2006 Report Share Posted October 30, 2006 Strange, are you sure the car doesn't have a factory amp? Quote Link to post Share on other sites
ramman949 Posted October 30, 2006 Author Report Share Posted October 30, 2006 Correct. No factory AMP. I guess Im going to recheck the wires, but Im positive there matched up correctly. Quote Link to post Share on other sites
jimmy303 Posted October 30, 2006 Report Share Posted October 30, 2006 If I remember correctly, the rear speakers have 2 drivers, a woofer and a mid/tweet. The left woofer is white/red+ and red/black-, right is blue/yellow+ and red/white-, the mids on each side are blue/yellow+ and red/white- I believe.(At the speakers.) You may have only tapped the woofer. Quote Link to post Share on other sites
ramman949 Posted October 30, 2006 Author Report Share Posted October 30, 2006 I see. Thanks for for you help. I used a wiring harness and matched each color correctly so Im not sure what you mean about the different drivers. I also noticed that if I put the rear setting to SW, I loose front and back fader options. Not sure if thats a issue or normal, but I noticed that. Again, I used a wiring harness and matched all colors. I then plugged my amp and subs into the SUB preouts. Not the REAR preouts, not the front pre-outs, just the SUB preouts. Doing so allows me to used the SUB ICON to turn them on or off and change the sub output level. Quote Link to post Share on other sites
Mo-D Posted October 30, 2006 Report Share Posted October 30, 2006 I'm not sure of the D2 has the sound field settings (stage, living room, etc) like the Z1 or not, but if you have that turned on the rears will sound that way. It has to do with time alignment of the sound, similar to a home surround sound system. Give that a try. Quote Link to post Share on other sites
jimmy303 Posted October 30, 2006 Report Share Posted October 30, 2006 You seem to have it correct. Look under the rear deck and see if there are 2 sets of drivers. Quote Link to post Share on other sites
ramman949 Posted October 30, 2006 Author Report Share Posted October 30, 2006 Thank you, but no, mine doesnt offer that. It does have HPF or high pass filter which I turned off, on, doesnt change much other than let some highs though or not. Volume level stays low and muffled. Quote Link to post Share on other sites

I will recheck, but I dont remember having any extra wirings (the colored thin ones) hanging out. If I remeber correctly, all color wires from the harness matched the colored wires comming out of the head unit. I will recheck though, but Im faily positive there are no extra wires except for VIDEO/sound inputs and outputs for external monitors, camera or DVD player or whatever you want to use it with.

jimmy303 Posted October 30, 2006 Report Share Posted October 30, 2006 Speaker. Does the rear speaker location have more than one, ex., woofer and tweeter/midrange? Quote Link to post Share on other sites

ramman949 Posted October 30, 2006 Author Report Share Posted October 30, 2006 Ah I see. No. It doesnt. I have a pair of RCA's for FRONT I have a pair of RCS's for REAR I have a pair of RCS's for SUBWOOFER I have my AMP connected to the SUBWOOFER RCA's. The rear speaker setting is FULL (for the rear speaker RCA's) which means its all the sound goes though. You can set it to SUB to use the REAR RCA outputs as your SUBWOOFER line too. Changing the REAR RCA outputs to "SUB" WILL CAUSE the rear speakers to act like subs too. I think they do that for people whom have no amp, but want BASS to there rear speakers (like 16x9's).

ramman949 Posted October 31, 2006 Author Report Share Posted October 31, 2006 Everything checked out fine. My wiring was fine. Buddy of mine said his rear speakers are the same way from factory. I probably never noticed when I was using the stock radio. Thanks for all your help guys. Quote Link to post Share on other sites
