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.

Great product well build saved me having to solder!

Used for my 96 nissan 200sx. Worked great and was easy to use.

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.

Huge timesaver

Phew, I'm glad I found these. Be careful about which size you need. These actually fit my 2015 Infiniti Q50 with Bose, ONLY in the front doors. I had plenty of the other sized adapted, which fit all other locations. However, these were for the 3 1/2" speakers found in the front doors. Should work for ant quick connect speaker, and saved quite a bit of soldering, which would have been more than I expected because of the uniquely complex factory connections.

To plug or unplug. that,,,, is the answer.

They worked great. This plugs made my job sooooo much easier. no messy black tape, no welding, no nothing. Just plug and play. and unplug if you want to.

2014 Kia Soul - Great sound & value

Installed in back doors of Kia Soul, pushing them with Kenwood Excelon X302-4 amp (50W RMS x 4), and an Excelon head unit. These speakers sound great!
