Metra 70-7551

This product is great compared to the one where you have to keep adjusting, all this does is make in the installation a lot easier. Instead of connecting wires to each speaker, you just plug it in to your new head unit and the rest of the wires are pretty straight forward to connect. Love it and I am glad that someone came out with this product.

Metra 70-7551

If you are going to change out the head unit in a Nissan Maxima with the Bose system, this is a must! You can keep the factory amps and save yourself many hours of heartache! Instructions are simple.

good value

It woked/fit perfectly.

Not for aftermarket radio with 4 ohms

Tried this harness with a JVC KW-XR810 HU. Volume was to lower. Lowered the factory speakers by 50% The HU was 4 ohms and my factory was only 1 ohms. I used a PAC-ROEMNIS2 instead.
Installed on a 2002 Infinity I35

RCA

This product was definitely worth the price, I have no problems with the cords or engine noise. I would definitely use the brand again if I ever needed some RCA wires.

Works

I used this harness for an 02 nissan maxima with bose. I did a complete amp bypass so i only used the wires like power and ground for the new head unit. But it fit the factory harness well and my job is done.

Works well and fits my Bose system well

Perfect for your 350z with factory Bose

This harness was listed under infinity G35 with Bose but when the gentleman from Sonic crossed referenced it with my 350! It was an exact fit! Just what I need! So easy to wire! Took 5 minutes!

time saviour

Saved alot of time and works like a beauty.

Wire is wire :P

I really appreciate that each wire was identify clearly.

Simple direct hookup

Purchased for my 2002 Pathfinder with factory Bose amps. Simple install, quick, no mess. However, my head unit has standard lower voltage line levels, so max volume is fairly low to drive the amps. Would work better with a head unit with higher voltage preouts.

Great

Made it easier to install my new stereo.

I worked great, easy to install, highly recommended. I used this to connect my head unit to my Factory bose system using my aftermarket head units RCA outs. works great and sounds great.

I sent this one back because I had heard of problems people have had with Bose system.

nice

This is great for bose powered factory amp/speakers.. but I still ended up replacing all the speakers and the amp since the sounded like crap...

very good

I bought Installation Kit for 2000-2003 Nissan Maxima Vehitsles and very pleased with the service and product quality, thanks a lot.

Works pretty well

It fit pretty well and looks good in my 03 Maxima. I wish they were a little easier to reach though, as I had a few questions during the install. I also couldn't find any to-do videos like they said they had.

Didn't need, but looks like it would do the trick.

The car's original stereo had already been swapped, so the kit wasn't necessary, but am glad is was included, as I can see this product saving a tremendous amount of time and hassle.

Metra 7551 Harness

Love the Metra products. Makes installing aftermarket head units much easier. Harness plugs right into auto .

Wiring harness

It looks like it is well made. I bought this thinking I was going to install a aftermarket radio, but I changed my mind. So I will not be using the harness after all. I'll keep it because if I'm not satisfied with the sound is will be installing a Alpine deck in place of the factory one.

Plug and play!

Factory Bose amplifier integration with the simplicity of plug and play stereo installation. Doesn't get better than this.

Metra Electronics for the win

Easy to use and perfect fit for the Nissan. Good quality, affordable. Great way to add new headunit into vehicle.
