It is a quality product but its diagram could use some help. Had some of wiring missing and did not say what to do with a couple of wires. Called in and the person helped but seem rushed to get off the line with me. I hung in there and kept asking what was what and did get it figured out.

Pros: Plug ins fit All there Call in help

Cons: Could have a better diagram

I like that it has its own power supply to prevent unwanted noise from radio interference and engine noise. My one problem with this unit is that after a couple of adjustments the dials seem to get scratchy, imagine the noise you get from a dirty volume knob on an old stereo console. Other than that I like it. Once it's set it's set and you don't have to mess with it.

Pros: Integrated power supply

Cons:

Nissan Frontier Rockford Fosgate

Works perfectly on my 2006 Nissan Frontier (Nismo) with the OEM Rockford Fosgate sound upgrade from the factory. Plug and play and did not need to adjust the interface levels :) . No hissing or loud popping of any kind. The actual module is quite large, but luckily there is plenty of room behind the Heating\AC controls (under the stereo) to tuck it away. Just a side note (had to call Crutchfield Support to confirm). On this module, each speaker has 3 wires to connect into from the Aftermarket Stereo; There is a High Level (+), Low Level (+), and Negative (-) wires (total of 12). The "Low Level" wires are not to be used if the aftermarket stereo does not have it dedicated (super rare for an aftermarket stereo to have dedicated Low Level speaker output). Just use the "High Level (+)" wires for the speaker positive input and the obvious Negative input and tape away the remaining unused four Low Level (+) wires.

Pros:

Cons:

Easy to install, helped to reduce base popping little to zero on my oem bose subwoofer and amp in my 2004 Nissan 350z

Pros: Easy to install, clear wiring instructions and labeling.

Cons: Larger unit which results in a cramped space behind the radio.

Get It Pre Wired! It's worth it.

Loyd from Griffin, GA on 2/11/2019

2006 Nissan Frontier

Verified customer (What's this?)
Verified employee purchase (What's this?)

Bought this for my Nissan Frontier, I had it "Ready Harnessed" and it was a simple plug and play. The only problem I had was a hissing sound ( like the volume was turned way up but no music ) coming from the speakers. I quickly called the help desk and they talked me through some adjustments.

Pros: Much easier with the pre- wiring

Cons: No instruction on how to adjust

Excellent product! Highly recommended

Tim from Aurora, CO on 1/29/2019

Verified employee purchase (What's this?)

I installed this in my 2005 Nissan Xterra SE which had a stock Rockford Fosgate head unit (with subwoofer) which I upgraded to a Pioneer deck. The installation was very straight forward. I just crossrefenced the PAC interface wiring diagram with the Pioneer double din wiring diagram using Posi-Products harness connectors and Presto! Everything worked including the subwoofer and subwoofer amplifier.

Pros: Harness cable length Adaptability

Cons: None

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 ]
2 answers
A
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
A
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 ]

A
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.
[ Philip  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
[ Michael  Feb 06, 2019 ]
