Great Product, but installation not obvious

Douglas from Cincinnati, OH on 7/12/2018

Crutchfield Customer Review (What's this?)

My only complaint about these is that they didn't come with any installation instructions. They are not at all symmetrical, and there are are literally 8 different ways they might be inserted into a wall plate or wall strap. I couldn't easily find any instructions on the internet. Afraid of breaking one trying to insert it incorrectly, I called customer service. They didn't know off hand, but they were able to find something and tell me how to do it. Some unnecessary time and aggravation. Otherwise I would give them 5 stars. Once you know to insert it from the back with the proper orientation, they can be snapped in and removed from the plate with reasonable ease.

Pros: Only one insert needed per speaker. Can provide connections for twice as many speakers in a wall plate or strap with a given number of openings, six speakers max per single plate or strap.

Cons: Not at all obvious how to install the inserts. No installation instructions.

These are awesome! take up less space/fewer slots than Banana plug terminals less risk of shorting out Tidy

Cons: not a well publicized option

A gem of a product.

Crutchfield Customer Review (What's this?)

I'm putting in a 7.1.4 Dolby Atmos theatre in our newly remodeled/ add-on home and these little gems are awesome. A very clean design and functionality hits the bullseye. Nothing to complain about.


Cons: None

Great Product

Crutchfield Customer Review (What's this?)

Easy to use and adds the professional finishing touch.

Pros: Cost effective and more compact than the banana clip option.

Cons: none

Great product, easy install.

Me2 from Corning, NY on 4/4/2014

Crutchfield Customer Review (What's this?)

I ordered a set of these to finish the installation of in-wall wiring for my surround sound speakers. They were easy to install and the material feels more rigid than cheaper alternatives from the box stores. I'll definitely consider ordering these again for other installs.

Pros: customizable, easy to install

Cons: a bit pricey

Great way to connect in-wall wiring

Dan B. from Upper Michigan on 1/26/2014

Crutchfield Customer Review (What's this?)

This is the best way I've seen to connect in-wall speaker wiring. The Keystones are color coded with red & black dots on both ends, so you'll always maintain proper speaker polarity. It's best to "Tin" the speaker wire before insertion, and insert the wires with the keystone upside-down. Gravity will then keep the contacts open. Then tighten the screws and insert it into the plate.

Pros: Simple, secure, professional way to install speaker wiring.

Cons: There are no instructions included.

Easy, compact, works well

DaveH from Madison, WI on 3/15/2012

Crutchfield Customer Review (What's this?)

I bought four of these little guys to wire my surround speakers. Two of them are snapped into a plate by the stereo system. The other two are in a plate on the opposite wall. All of the wiring runs down the wall and through the basement leaving a nice, finished appearance upstairs. The best thing about these particular speaker connectors is that they are compact. A single four-port wall plate can hold two of these speaker jacks, an F-connector (cable TV) and an RJ-45 jack (network/phone). Other speaker connectors I saw had only one conductor, not two, requiring twice as much space (and twice as much money).

Pros: Compact. Fits in standard wall plate.

Cons: The screws that secure the wire can get out of whack (presumably during shipping). Easily fixed by unscrewing all the way until you hear a slight click and then tightening again.

Overview: The On-Q WP3425-WH is a white plastic Keystone insert with a single speaker outlet, designed to be used with On-Q Keystone straps or wall plates. The speaker outlet has screw-down clamps for up to 12-gauge speaker wire. In addition to this insert you will need the appropriate in-wall wiring, along with either a standard keystone wall plate or an outlet strap with a decorator wall plate.

Installation Overview: The OnQ Keystone connectors (available in F-type connectors, Cat 5/RJ-45, Speaker screw terminals and binding posts, and multi-colored RCA jacks) provide terminals for in-wall audio and video cables in a single-gang or dual-gang box. Outlet straps and standard keystone wall plates, into which the keystone connectors snap, are available in 1, 2, 3, 4, or 6 port versions. When using an outlet strap, a matching decorator wall plate covers the outlet strap and wiring for a clean installation.
