Best Value

I got what I needed for the value and worked perfect.

No need to cut the factory wires

Just buy this harness for your car and save time with not having to cut your wires. All you have to do is plug this in to your factory harness and wire to your new radio harness with ease. It's as easy as it gets.

Plus it makes it easy to put the old radio back in should you decide to trade the vehicle in later and keep your nice after market radio.

Good product

Does what is supposed to do. Fits stock harness.

Metra 70-7550 Wiring Harness Adapter

I purchased this wiring harness adapter for a 1998 Nissan Altima. I recommend this adapter for this vehicle. It was almost perfect match. Some of the wires that did not match were simply because the stock radio did not need them. The wiring directions worked okay. Understandably, the directions cannot know exactly what every car's original harness wire colors will be, but it was easily figured out.

fit right in

worked perfectly! cheap and easy! great buy!!! 1997 sentra is what it was installed on.

great product

Worked like a charm. Pre cut wire ends makes for quick install. Would buy same brand again

Worked great!

The wiring harness I purchased from Sonic Electronix was just what I needed to install my new car stereo. It worked as advertised and arrived in a timely manner.

Great value

Just what I needed to install my new head unit into my xterra everything worked just fine

Great product

Good quality good service I would recommend

Metra 70-7550

I have a 2006 Nissan Frontier and the harness was easy to connect and fit perfect.

Ground

For this harness came with no ground wire or insert to wire into place. I am very disappointed in this when this car and stereo system is for a 16th birthday.

Great value

worked great for wiring the stereo, recommend sonic electronix to anybody

Great product

Installing my radio was simple. Worth the money not to hardwire my stereo. Plus I'm able to reinstall my factory stereo if I wanted to. I would highly recommend.

Worked

Made connection to new stereo easy for my '11 Frontier with 6 speakers. For some reason shows not fitting, but that is what I needed. Customer service was quick to replace the wrong one, excellent job! Also, the fir is pretty tight, and ended up pushing out one of the speaker pins, but after seeing it, all went in fine.

Makes installing aftermarket radio a breeze.

Made it super simple to wire up an aftermarket radio in my 2004 Titan. No splicing into wires just plug into factory harness and match up the wires to the new radio, To reinstall OEM radio just simply remove this item and plug factory harness back into original radio.

Sweet Kit!

Looks great in my frontier. Looks OEM. Makes the install very easy. Great fit!

Metra 70-7550

Wired everything perfect didn’t like the fact there was no ground but made it work

Harness worked perfectly

The harness worked perfectly for the 2001 Nissan Sentra and for the JVC radio I bought this with.

Perfect fitment for my 2005 nissan pathfinder!

This dash kit was PERFECT for my 2005 pathfinder! Absolutely no modifications necessary and it makes it look like it's a factory double din headunit in my truck! Thanks Sonic!!

Perfect fit guaranteed.

I'm always skeptical about install kit because they usually require modifications. This one was wham-bam-thank-you-ma'am....perfect fit.

great value

Super product came with a lot of extras unfortunately they weren't necessary for my install.

Item works fine, the double din kit is not a perfect fit for my Nissan Frontier but it is very close and still looks great installed

2008 Nissan Frontier LE

All I needed was the square ring trim that goes around the stereo. I replaced my stock double din for a Pioneer App radio.

Well made part!

I would recommend this part if you buy a single D.I.N. radio. I purchased a double DIN, so it was not needed, but hey, its free from Sonic Electronix.

I am a VW tech so I have seen tons of hack jobs when it comes to radios. This is a nice piece.

great product

fits my after market receiver perfectly. Looks OEM

The part doesn't fit...

I purchased this part specifically to receive the bezel to finish the new Pioneer deck system installed in my Nissan XTerra.

Even though my dash console is stock and has not been modified the bezel does not fit as described in the installation manual.

Great Product! Fit well! Exactly as listed!

Great product! Fit very well for my p4100dvd player! Just wish the double din trim ring was sold separately but other then that, great price as well!

great value

Fit very good!

Great Value

The price is great and it's easy to use. The only down side is at night the light from the face of the stereo is way too bright. But still a good stereo for the price.

great value

Super product came with a lot of extras unfortunately they weren't necessary for my install.

Works

This came free from sonic with the purchase of the radio it works

Metra 99-7581

This stereo kit fit perfect in my 2006 Nissan Frontier and shipping was on time.

Has what you need

The metrakit was included in the radio package so that was nice.
I used only the double din trim piece in my install as it was better than the kenwood one
