Overview

by Crutchfield's

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.

KEEP READING

The Mobile Electronics Series Connector Kits come with various assortments of special Posi-Lock® and Posi-Tap™ connectors 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: 60 days.

What is the advantage of these (cost more) over crimp connectors which keep the wire straight and can provide a watertight seal?

[ RYAN Jun 29, 2021 ]

2 answers

Crimp connectors are not water tight. I tried these connectors for the first time, and was satisfied with their security. In some spaces, a straight connection may not always be desirable.

[ HARRIETTE Jul 13, 2021 ]

Don't need a crimper and easy to change incorrect wire hookups. Can reuse the crimp connectors. The only downside is that they are bulkier.

[ ALFRED F Jul 13, 2021 ]

I'm wiring up a new head unit. How many wires can these connect together? Between my head unit, vehicle harness, factory amp, MicroBypass, and steering wheel controls, I have 5 ground connections that need to be tired together. Would a single connector hold those together?

[ DENNIS Apr 16, 2021 ]

3 answers

No. 2, maybe 3. For 5, just go to Lowes, HD, Ace, etc. and get a red or yellow wire nut. Make sure those are taped up tight. Don't want any ground feedback.

[ CARL Apr 16, 2021 ]

No, a single connector wouldn't work.

[ Troy Apr 16, 2021 ]

I wouldnt chance it. These are very small and 5 wires are a lot for one. They are perfect for splicing wires on a harness, but 5 is asking too much of them. Better off soldering them all

[ Ryan Apr 16, 2021 ]

[ DENNIS Apr 16, 2021 ]

1 answer

Hard to say as it will depend on the size of the wires. Probably not 5 wires unless they are pretty small. Just use a regular wire nut and tape it on after so it can't vibrate loose with your kick ass jams..

[ Steven Apr 16, 2021 ]

Can you use this to connect one wire to the middle of another wire (like a T-tap connection)?

[ JAMES Dec 14, 2020 ]

1 answer

These connectors join the ends of wires together. Posi-Products does make tap connectors which will connect wires like you described and you can find the tap connectors here: https://www.crutchfield.com/shopsearch/posi_tap.html

[ JASON Dec 31, 2020 ] Staff

Will this work with guitar pickup wire, which is usually between 42-45awg?

[ Dave Jun 03, 2020 ]

1 answer

As long as it fits I'm sure it could work. However this is definitely not it's intended use. It is fairly cheap so if it doesn't work your not out a lot. I am also the type that tries new ideas. If you go with it I hope it works Okey for you.

[ JOSHUA D. Jun 04, 2020 ]

How do I install & wire my after market dash speakers on my 2016 Ford Taurus there's no connector wires just a hole ?

[ CASEY May 27, 2020 ] Staff

Will one box be enough to wire everything if you bought a new head unit and harness for your steering wheel?

[ Michael Jan 13, 2019 ]

1 answer

I think I would go for two packs. They're pretty inexpensive and better a few left over than not enough.

[ Geoff Jan 13, 2019 ]

Do you need these with the wire harness that you can buy specific to your vehicle?

[ greg Dec 28, 2015 ]

3 answers

i did not use those, i soldered the cables together (most secured)

[ GUSTAVO Jul 25, 2016 ]

You do not specifically NEED them, but they are very much worth the purchase, ESPECIALLY if you are wiring a steering wheel adapter up also and made a few wiring mistakes. It makes rewiring painless, just unscrew it.

[ AMIR May 07, 2016 ]

NO but they make the wiring a lot easier.

[ JOHN BRYAN Dec 29, 2015 ]

What amperage/wattage are these connectors rated for? I'm assuming at least 10A at 12V?

[ joshuo Sep 02, 2014 ]

3 answers

True

[ KRESS Sep 02, 2014 ]

I think 10a would be fine . I used these on speaker wire mainly. Then solder power wires

[ TERRANCE M Sep 02, 2014 ]

I used them on a 20 A. Works just fine.

[ RANDY Sep 02, 2014 ]

What gauge are the connectors?

[ Veronica Jun 05, 2014 ]

3 answers

Works well with 16 gauge and below. I used it mainly for head unit connections, which sometimes require re-wiring, so it was convenient. I tried using it on 14 gauge Monster Cable speaker wires, but it barely fit and the connection didn't seem secure. Hope this helps.

[ NESTOR Jun 08, 2014 ]

About 14 ga typical car radio wiring

[ TROY Jun 07, 2014 ]

These are not meant for larger gauge wires - anything 18ga and below will work with these. I personally didn't care for them after installing so I stripped them off and ended up soldering the wires and using heat shrink tubing to cover.
