Worked like a dream as always! Only complaint is that it was a little bulky for my dash so I had to do a lot of maneuvering to get my radio to fit. All in all fantastic! Always good service with crutchfield!

Great, if it's meant for your vehicle
Crutchfield customer from Heartland, TX on 5/26/2020
well built with tons of options.
Pros: quick and easy wiring with a ton of options.
Cons: If this harness is not correct for your vehicle or current setup, you may pull your hair out trying to solve the problem. Luckily there is always Crutchfield Support to save your bacon.

Worth every penny
Crutchfield customer from Elizabethtown, PA on 3/4/2020

Product was well packaged. Arrived very quickly and very easy to install. Directions were pretty clear. I had one wire crossed up but when I called the customer service at crutchfield was amazing. This product did exactly was I hoped and that was allow me to use my factory amp with a new head unit and not have to have any custom work done that would be expensive. I would highly recommend it.

Factory Bose system upgrade
Crutchfield customer from Grand Ledge, MI on 4/8/2019
2000 GMC Yukon Denali
I needed one of these to connect my Bose system to my aftermarket receiver. I wasn't expecting much and wondered if I should get a new amp and speakers. However, I was blown away by the sound from my system after the upgrade. I honestly did not know it could sound this good. I am so very please with this and highly recommend it to anyone considering an upgrade to their factory Bose system. Thank you Crutchfield!!

Just works!! but need to read manual about Hi / Low power Amp rating
Crutchfield customer from Woodside, NY on 11/17/2018
2002 Cadillac Escalade
It just works!! No hiss, no noise, no thumb, no cracking sound. One confusion thing with wiring was that there were 2 sets of wires for hi and low power speaker connection. I needed to read the manual carefully to understand what "hi" and "low" meant. I checked my stereo spec to match AMP power rating accordingly. I wish there was a flicker switch instead of separate hi/low wires. Just too many wires hanging out from the unit, don't you think? But it performs flawlessly.
Pros: It just works!!
Cons: too many wires...

I love Crutchfield. Not just because they had the equipment I needed, but because they took the time to explain what I needed and how to install. Shopping with Crutchfield gave me confidence in a confusing world.
Pros: Great service, great product.

Easy Install
Richard J from Sugar Land, TX on 1/2/2018

Was easy to install..The problem I have with this unit is that the rear speakers play very low. I have tried tweaking the unit with the adjustment screws and still the sound is really low..Will probably replace this with something else. I do not recommend this unit it personally.
Pros: No problem with the Install
Cons: Sound is really weak on the rear speakers

Works great
Dj from Helena, Ohio on 7/14/2017

Works great as it should not too difficult to hook up but could be a little easier maybe.
Pros: Does what it's suppose to!
Cons: A few different ways to hook it up depending on your car would be nicer if it was car specific not just car general i.e. Certain manufacturer and years.

Kathryn from Kentucky on 3/31/2016

The interface is easy to install one side you use the wiring harness from you vehicle and the other goes from the box to the your stereo. All wires should be used because it comes with high and low.
Pros: Easy to install
Cons: n/a
