Perfect Adapter for Older Nissans
This little adapter salvaged my 1998 Nissan 240SX's decrepit sound system, because without it I could not have replaced my speakers. It was absolutely intuitive to install and took only seconds. I highly recommend it.

Metra 72-7400
These worked perfectly to get the Infinity Reverence series speakers connected to the factory wiring in my Maxima

Good Buy!
I ordered this on April 24th, got shipped on April 27th, received it on May 2nd.
My front speakers were stock and one was completely blown, I installed my Pioneer TS-G1642R's in my front doors with this product.
It's a VERY easy plug and play device. My system now sounds a lot better with these up front.
I [will] be ordering from Sonic Electronix again, very useful for car and home audio.

Does not fit 07 + Altima's
These harnesses are incorrect for the 4th generation altimas. These probably work great for older models. But they do not fit my car.

Metra 72-7400
I order the Metra 72-7400 and i have to tell you its the best thing they came up with you just plug it in your factory wire and your your ready to hook up your new speaker if you ever putting in after market speaker you have to get some of these

Great value and makes for easy install w/no cut wires
In my opinion this is the only way to go when connecting aftermarket speakers using factory wires. No cutting wires, no mistakes, etc.

Works as said
I needed this for my tweeters in the dash. Does not fit the door speakers in a 06 Nissan x terra. Looks the same just too small for those who need to know.
