These are actually really awesome and I recommend getting a pack or two. It is nice because if you mess up you don't have to untangle the wire or cut it shorter. Just cut the tube in the middle and pill the two wires out of each side. I prefer these better then other wire connectors.

Very easy to use. Glad I ordered them with my head unit. A lot cheaper then Autozone. Thank you Sonic!

They make it easier and faster to install a car stereo.

Connectors were pretty cheap but they got the job done.

this item worked out great

I bought these because they had a good amount, but i didnt end up using them because I went with the better option of soldering all of the connections instead.

These connectors worked ok but are a little cheap and I could have used a couple of extra pieces to make up for mistakes. If you are not on a tight budget, I'd recommend the more expensive connectors.
