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.

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.

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!

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.

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.

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.
