My 02 G20 has a cd changer tried a regular harnes. Needed the cd changer harness hooked up as well hopfully this harness works?
[ ANDREW  Jun 11, 2020 ]

A
CD changers that can be controlled by the stock radio will no longer work with an aftermarket radio installed. I wish I had different news for you on that

Q
Will this work with 2012 Xterra pro4x with Rockford fosgate stereo? Wanting to install JVC 740bt.
[ Rebecca  Oct 07, 2019 ]
1 answer
A
Yes that is the correct harness for that vehicle to retain the factory amp. We also recommend a dash kit, and steering wheel control adapter (if you need them). You can connect with one of our product advisors to make sure you have a complete cart: https://www.crutchfield.com/I-rET1c290/S-SUliZgSTXG7/support/ContactUs.aspx

Q
if my 2004 pathfinder amp is not working and I install a new stereo, can I bypass the factory bose amp and still use the bose speakers?
[ koi4fun  Sep 08, 2019 ]
1 answer
A
If you replace the factory headunit and bypass the amplifier, we recommend replacing the factory speakers with aftermarkets, so you don't risk damaging the new head unit.

Q
The instruction says the low level inputs are for radio up to 25 watts x 4. My Pioneer says it's 14 x 4 RMS but 50 Watts Max. So do I use the low levels or the highs? Instructions aren't quite clear.

Q
My 2010 frontier has a Rockford Fosgate system, this unit- which apparently Crutchfield is recommendong - says it allows you to use the stock Bose amp. Do I have a Bose amp and do I truly need this?
[ J  Apr 30, 2019 ]

You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with your factory system. They will be able to pull up your vehicle and see if this will integrate. If it does not, then they will also be able to discuss other options with you.
[ Krissy  May 08, 2019 ]  Staff

While the description for the harness does state Bose, it is also used to retain other factory amplifiers as well, such as the Rockford Fosgate amp in your truck. The harness is needed to retain the use of the factory amp.
[ Calvin  May 01, 2019 ]  Staff
Q
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?
[ Jerry  Feb 03, 2019 ]

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 ]
A
I did not use this in the 03 Altima. I just wired directly to the wiring harness.
[ P  Feb 07, 2019 ]
A
On my g35 with Bose system there was a choice on harness selection, with or without Bose system
[ RALPH  Feb 07, 2019 ]
A
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 ]
A
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 ]
A
Try and turn the volume up on factory stereo before disconnecting it (turn volume to full then turn key off)
[ john  Feb 06, 2019 ]
A
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
