EFX Interconnects

Jon from Brunswick, OH on 2/13/2019

Verified customer (What's this?)
Verified employee purchase (What's this?)

These cables look like they are well made but from a design stand point not that great. If rca on component (amp, receiver, etc.) are recessed the outer barrel will not clear. In my case will not work with Alpine PWE-S8 powered sub, unless you remove threaded barrel. Also as others have said, too tight may damage whatever you plug into. I hope this review helps.

Pros: Looks like good quality.

Cons: Poor design, too hard to plug in.

Great Vaule for the Price

Tom from Newark, DE on 6/4/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

Nice RCAs at a reasonable price. Not much to say other than that. I've used everything from super cheap to very expensive RCAs over the years and I've yet to notice a difference between them. The concern with the really cheap ones is that they'll fall apart or fail due to cheap construction. The expensive ones are absurd for most systems. Maybe for guys doing stereo competitions it might make some miniscule difference, but your ear sure isn't going to know what. I've bought these before and will gladly buy them again when the need arises.

Pros: Good Quality Reasonable Price Decent Selection of Available Lengths

Cons: None

Really good cables

Robert from Albuquerque, NM on 1/17/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

These are really good cables. They fit to what you're plugging them in to is tight, but not that tight that you can't plug them in. This means they will not come loose arbitrarily and cause problems down the road . I can't understand why someone would complain about the cables being too tight since that's what you want instead of having to constantly having to reconnect them because they have disconnected all on their own.

Pros: tight fit so they won't come loose. price

Cons: none

Works great, hard to tighten after connection made.

Crutchfield customer from Lincoln, NE on 10/2/2017

Verified customer (What's this?)
Verified employee purchase (What's this?)

Don't underestimate the length you will need. I almost ordered 12 ft, but went with 17 ft. It's a good thing because by the time you go up and down and through and up and down and through and around this and under that, you've used up quite a bunch of wire. The threaded ends are nice I think? They are really hard to make tight once you have them plugged in. I really like the idea that you can tighten these after they are mounted. But in practice, it is really hard to do. Especially on the head unit.

Hard to connect

Scott from Port Charlotte,Florida on 8/25/2017

Verified customer (What's this?)
Verified employee purchase (What's this?)

I used these cables to connect to a Rockford Fosgate amp. The RCA ends were hard to connect. Then I realized that u had to unscrew the plastic end to fit on the amps. Archaic fitting RCA. Very tight fit. So tight I thought that my amps RCA were going to snap into the amp housing. Don't know how they sound yet. I am glad that I did not break the connections on my Rockford Fosgate amps. No instructions with these cables.

Pros: Nice color

Cons: Hold onto your curse words for these folks! They are very tight!

Check 'em before you install them

Jeff from Covington, VA on 5/12/2016

Verified customer (What's this?)
Verified employee purchase (What's this?)

Bought the 12 footers. Should have tested them from my head unit's equalizer to the amp under the back seat before I took all the time to pull panels and thread them through, but I didn't, and what a mistake. Got them installed and plugged them in, and one channel had nothing but white noise on it. Pulled the pair back out, inspected the plugs, sheathing, protective casing, and could find no cuts, nicks, open connections, or dirty plugs. Looked like they had just come out of the package. Checked the cables with each channel, and one channel wire was fine, the other, nothing but static and white noise. Took them back and got a replacement pair which worked fine, and perform as I expected they should have with the first set.

Pros: Twisted pair wiring, heavy sheathing, tight connectors

Cons: Had a manufacturing defect out of the box.

Quality cable seems good and sounds good

John from worcester, MA on 2/13/2016

Verified customer (What's this?)
Verified employee purchase (What's this?)

Quality seems good and everything works without interference. Sound is crystal clear from my amplifier so what more can you ask for. I do use quality amplifiers too. A word to the wise; make sure you run this cable away from any power wires or other potential sources of interference. Even the best cables can't compensate for a bad wiring job. I've been doing home audio and car audio for a long time and learned that a quality cable is a must but there is a point in car audio where the ramp for what you get for what you spend is very steep. This cable is a good compromise if all you care about is the sound quality and it does this without breaking the bank.

Pros: Doesn't break the bank! Didn't have to pay for the marketing hype or gold this and that and still got a good quality cable. Does what those super-duper, gold this and that, superman monster cable RCA cables do for much less money. If you buy this you're not getting ripped off.

Cons: Doesn't come with the fancy looking graphics.

I chose these for an install in a Suburban. Head unit in the dash and amps in the cargo area - its a stretch. The EFX cables have worked great and their blue color hides well in the blue interior of the Suburban. I had to call Crutchfield, however to find out how to tell the two channels apart - it is subtle. One RCA jack on each end has blue at its base and the other has black. The Tech guy was real nice and didn't make be feel stupid about it - I did that myself. [ DanenG  Feb 04, 2016 ]

I have dual mono amps each powering separate 10 inch subwoofers. The amps have pass-thru RCA ports that allow a second amp to be daisy chained to the first. These short RCA patch cables do the trick without too much left over length. If I had my amp board laid out prior to ordering them, I probably could have used an 18 or 24 inch cable.

EFX makes some of the best RCA's on the market! [ Adam  Oct 18, 2017 ]

I used these 6 foot RCA cables for an amp installation in a Jeep where the head unit s located in the center console and the amps are mounted to back of the Sub box right behind the front seats. I didn't want too much length to have to deal with in this scenario. I've used the EFX cables on two installs now and have had no issues. It took a call to Crutchfield Tech Support for me to realize which was the left and right cable ends - the base of one RCA jack is black and the other is blue (duh). [ DanenG  Feb 04, 2016 ]
