1 question already asked

Installed in 03 Altima but volume is extremely low. It says let's you keep the Bose Amp but my car doesn't have the Bose system. Is there a different adapter for the car without an amp?

If your new radio system has an option to turn on and off the internal app inside the radio make sure it is turned on, I had the same problem, if I turn my app off then I get almost no sound through the speakers, but if I turn it on it's as loud as can be. Just to be clear I am talking about the app that is built-in to the radio not the one built into the vehicle
[ Armando  Feb 08, 2019 ]
I did not use this in the 03 Altima. I just wired directly to the wiring harness.
[ Philip  Feb 07, 2019 ]
On my g35 with Bose system there was a choice on harness selection, with or without Bose system
[ RALPH  Feb 07, 2019 ]
I HAD a Bose system (that died) but no Bose Amp. I used this same interface on my Infiniti plus I had to buy a new stereo. It works great, very loud. Perhaps you got a defective interface?
[ Jose  Feb 06, 2019 ]
I think if you don't have the Bose system, then you just need the regular wiring harness vs the Bose adapter and the regular wiring harness. I would call cruthfield if your still having issues.
[ Eric  Feb 06, 2019 ]
Try and turn the volume up on factory stereo before disconnecting it (turn volume to full then turn key off)
[ john  Feb 06, 2019 ]
I'm pretty sure if you're installing a stereo in a non Bose Altima you need a wiring harness not an imterface. The whole point of an interface is to retain the amplifier and make sure the speaker signal is not being amplified by both the stereo and the amp
