Great connector for auto stereo installations

High quality part for the price. The fit is good and the covering is sufficient for crimping and not exposing the metal insert

I was looking for a cheap way to replace my stock CD player with a head unit with BT and AUX inputs. I came across this product and decided to give it a try. It was easy to install using a Metra wiring harness. Works great. Only problem is BT sometimes takes a few minutes to connect, but this is not enough to deduct a full star.

Exactly what I needed to connect my iPhone to the car radio

These 3.5mm audio cables were perfect to connect my phone to my truck's AUX radio input.  Perfect length and the audio quality was superb!  The 6.35mm adapter is great for connecting to the output of my old stereo that has the old headphone connector.  This is a great deal for high quality cables.  This product was provided at a discounted price in exchange for my honest review.

This harness worked great to install a new stereo in my 2004 Mazda 3. The wiring pin out could have been a little clearer but I figured it out eventually.

Two stereo's and one antenna can be a problem. This is just the adapter you need to easily solve this problem. This was exactly what I needed to add another stereo to my RV and use the existing antenna. I connected one male lead to the back of the stock stereo, connected the male antenna lead to the female lead and ran an extension cable off the left over male lead to the new stereo. Problem solved.

I replaced my factory stereo in my 2007 Ford F-150, ordering only the Head unit, installation dash kit and appropriate wiring harness. What I didn't realize is that I would need an additional adapter to plug my factory antenna into the new stereo as well. I discovered this at 5pm on a Friday evening. I quickly went back to amazon, and came across this adapter that had mixed reviews. I ordered it, paid a small upgrade in shipping and low and behold had it on my doorstep by 10am Saturday morning. Made the connection using one of the two supplied adapters and the radio works like a charm. Very simple installation and amazingly fast delivery.

This item is perfect for running three different signals through my vintage stereo system.  I output my TV, DJ mixer, and the third is an 1/8" I csn plug into ipod/computer/phone.  I've been using it a few months and it hasn't let me down!

This is just what I was looking for to add an auxiliary port to my work vehicle.  I've tried several transmitter type modulators and none of them worked at all.  (I heard this is because of a new power limitation set by the FCC)

The sound quality is pretty decent and is almost as good as what I've heard using other stereos with a built in auxiliary port.  Waaayy better than tape adapters or FM transmitters.  If you can't replace your radio for whatever reason and you need an input jack, this is probably your best option.

Installation is pretty straightforward but you will need to be comfortable removing your radio (and the dash in my case) as well as locating and splicing into a power wire or the fuse box.  You may also need antenna adapters.  Using Metraonline.com is an easy way find out if you do.

The only things I don't care much for are the el cheapo switch assembly (even the power switch itself is touchy) and the freakishly thin power and ground wires.  If it weren't for those issues I would give it 5 stars..

Was absolutely the connection I needed for using a portable CD player in my new Mazda which did not come with a CD player but did have usb ports and a 3.5 mm input.

Slickest connection for wiring. Hard to find in auto stores.

I use an array of different connectors and I must say, these are top quality. They are Perfect for audio installation and whatever you might find a need for them to be used as. Some plastic connectors are brittle and crack but these feel very sturdy. When used correctly with a crimp tool, these butt connectors are among the best I have used

I bought this to connect a radio to my Geo car, the quality of the cables is very good, and it just fits perfectly with the factory connector, highly recommend it!

I used this to add an mp3 player to my 2006 Mazda MX-5 Miata Bose stereo.  It was easy to install and has a long enough cord to easily reach anywhere in the car.  I have it going into my center console. Very well made.  Shipped and arrived very quickly from China.  Works great for playing any content from my Galaxy S4.

Easy to install and does what it is supposed to do. Great to connect an amp to any factory radio.
