Great Product

Crutchfield Customer Review (What's this?)

I needed 2 of these adapters that were short enough for the back of my after market radio. My vehicle has tight space that excess wire wouldn't allow a proper fit. This length was the only one i found that was just the right size i needed.

Pros: Length is perfect for certain applications, easy to see colors, sound quality is good (it was best for me when i had a ground loop isolator), price is good (best bang for your buck).

Cons: Depending on what vehicle you have you may need to use a ground loop isolator. My vehicle was the case for that.

I needed these in order to split the 2 RCA inputs from my headunit into 4 inputs, plugged 2 of the adapters in and viola! all done!

Pros: great quality and connections, color coded so you can separate left and right speakers consistently

Cons: none!

Handy addition

Crutchfield Customer Review (What's this?)

This makes it possible to take the audio from an older (mono) recorder into a stereo TV set. Not true stereo sound, but much better than one speaker only.

Pros: Good price and exactly what I needed.

Cons: Could be a little longer.

Great product, must have for the radio which has only two pre-out and you want to listen in all your four speakers.
