Our take on the Posi-Products™ Car Stereo Connectors

by Buck Pomerantz
Posi-Products

Posi-Products connectors help make your electrical connections fast, easy, and reliable with no crimping, soldering, or messy tape. Just strip your stranded wires, insert them in the caps, and then hand tighten the two caps together — the wire ends get locked between opposing cone shapes to create a water-, dirt-, vibration-, and heat-proof housing. You get a strong, low-resistance electrical connection, and you can reuse the connectors, too.

The Mobile Electronics Series Connector Kits come with various assortments of special Posi-Lock® and Posi-Tap™ connectors with gold-plated contacts to integrate your aftermarket equipment into your vehicle's electrical system. Experienced installers have selected the contents of each kit carefully, so you can be sure you'll have all the right connectors necessary to get the job done.

This Car Stereo Connector Kit comes with 16 Posi-Twist™ connectors — enough to hook up the speakers, power, and accessories in most car stereo installations. Warranty: 30 days.

Fair product

Written By Lee, Missouri on Monday, June 09, 2014
Crutchfield Customer Review (What's this?)
 
These connectors work, but they are not 100% secure and reliable, plus the harness assembly becomes unnecessarily bulky with this method. After finding a loose connection and wrestling the harness through the opening for the receiver, I very nearly pulled it out so I could solder the wires in line and then insulate with heat shrink tubing.
Pros:
Quick and cheap enough. Probably a good choice for persons that have no experience making soldered joints.
Cons:
Connections could be more secure.

Worth it

Written By CMG, Roanoke on Thursday, May 15, 2014

A little expensive for connectors, and I doubt that the sound is any better than simply crimping. As i was out, I simply added them for convenience's sake. Will never use anything else.
Pros:
Foolproof. Better connection than a crimp, I think
Cons:
None - perhaps relative expense

Originally thought these were crimp or crush lock connectors. only discovered they were screw type after opening the pack. Seemed to work OK but will be interested to see how well they work over time with normal day-to-day vibration in the car.
Pros:
Easy to use, quick to fit.
Cons:
Harder to use with more than two or three wires (such as connecting multiple earth wires to a common lead). A bit hard on the fingers once you have used a dozen or so. Reliability? Remains to be seen.

Absolutely easy compared to twisting them together with pliers and using electrical tape and hope that it stays. You still have to twist them together-you can do it with your fingers, put bottom end of posi-connector as far down as you can, put top on and tighten it down and you're done!
Pros:
much easier than using pliers and tape much easier than soldering
Cons:
you still have to twist them to start-it's not a no twist solution :) not as good as a seal as soldering, but pretty close

I would highly recommend using this product for installing a aftermarket radio. It's so easy to use if your a beginner or if you want to reuse them if you decide to upgrade your radio down the road. Twist the two wires together and slide them up the connector and twist on the cap for a tight seal, it's that easy.

Easy to use and install and reuse if u get another headunit. Gives it a tight seal when connecting two wires.

I bought these connectors at the suggestion of the Crutchfield rep. And very glad I did. At first I didn't use any and soldered most of the wire connections but then after I unplugged the solder I realized I forgot to join three wires together. So I broke out these babies and used them to connect the missed wires. Worked perfectly and glad I bought them.

Work well
