Having some issues. First off the sound is horrible. I had the bose system and changed out headunit and it seems 85% of sound is coming from front speakers 10% from sub and like 5% from rear deck speakers. The bose HU sounded much better plus the ipod music all sounds like ****. When i had the the tape thing in the bose with the plug in ipod headphone jack it sounded much better. does anyone have any suggesttions? i checked all of the sound setting and changed equalized settings, fad/bal all that when i fade to the rear i can barely hear any sound coming out of those rear speakers it sounds all muffled. someone help

make sured the loudness is turned on, make sure the High Pass filter is on, check connections. dont use the stage settings on the headunit, HPF works soo much better. the settings on the HPF and the sub are prob f'd up. check those settings and if you still dont see any improvement i suggest playing with the factory EQ settings that come preprogrammed and see if it makes any difference. if none of that works, your unit is prob bad and i would get it replaced. the sound from my D3 is very good, ipod plays very clear.

 

did you use the Pac-audio converter or are you sending the wrong amount of power to your stock amps?

 

hmm just thought, if the people that installed the unit found alternator whine they may have put ground loop isolators in and this would cause a loss in quality.

 

sounds like he just pulled the old Bose and put in the D3, although if amps were involved, insufficient power or having the gain too low would also do this. i do remember that some did have problems with the bose factory speakers and the stock amplifier when switching out the headunit. make sure that stock amplifier is properly bypassed.

 

I still have a hissing problem on mine when I mostly play the ipod. I don't think its the unit itself because when I play my girldreind's nano on there, it works perfect.

 

www.avic411.com can answer alot of question regarding the D3

 

Well ichanged some settings and it sounds better but not as loud as bose used to be i think its fluctuating power with stock amp im gonna just do full interior speakers i hope that gets rid of the problem

 

im figuring some pioneer interior speakers for doors and rear deck and then some jl audio 10 w3s for bass

 

definately not bypassed correctly. get yourself a good amp and some good speakers and it will sound awesome
btw i have all kicker products and im very happy with them.

 

yea, just change the entire setup if it bothers you that much. I HIGHLY doubt its the Avic D3. Whenever you integrate with the stock system, things can go wrong or not be perfect. After a long process of searching and asking the pros, this is what I find to be true.

 

thanks for the help guys i really appreciate it looks like ill be redoing all the setup and getting rid of evert\ything bose in the car. Probably keep it just in case i wanna revert to stock again one day if im gonna sell it

 

thats what i did, save yourself some money and do it yourself, its really not that hard. get a buddy with some car audio knowledge and wiring experience and you will be fine.

 

lol wish i had a buddy that knew about wiring and car audio cause i can do engine work but i suck with car audio and ****

 

oh quick question when the ipod is connected from the bottom plug does adjusting the volume on it do anything? for example when i had the BOSE HU i had the tape with the headphone jack in it if i raised the volume on ipod volume went up on speakers too does it do the same thing from that bottom jack?

 

its really not that bad, just some some other 350z forums and this one and you will have no problem. worst part by far is running the power wire into the cabin through the firewall, PITMFA!!

 

Sorry i have to update this thread my rear 6.5s are still like 40% lower in volume than the front speakers and the factory sub now goes in and out sometimes it works and other times it doesnt. please help lol i dont even know how to pull the unit out to look at the wires in the back

 

I installed the Avic D3 and found it to be an improvement to the stock Bose unit.
At the same time I also installed the Bluetooth module, Traffic Sat Radio module
and modified the unit to operate DVD's while driving.

Over all, I am very pleased. I have none of the issued you reported, perhaps the
problem is with the unit itself.

 

did u just plug and play it? cause when i hit certain bumps the sub turns back on then off. also when in vavigation mode if i have my ipod on and the unit is on full blast i dont hear the voice guidance. should i pull the unit out myself its just not loud enough and on radio mode its like the bose turned up to 24 or 25 not 31
