Crutchfield Customer Review (What's this?)

Worked great!



Needed item

Written by: Chris from APO, AE on December 26, 2015

Crutchfield Customer Review (What's this?)

This is a needed item if hooking up a hide away kicker sub and your head unit only has RCA hook ups.

Pros: Needed.

Cons: None

Works as intended, but unnecessarily confusing.

Written by: Devin F from North Carolina on December 11, 2015

Crutchfield Customer Review (What's this?)

The harness works very well, and is well built, but they use non standard colors for the wire which can be a bit confusing. Like one reviewer said, it's not difficult to figure out, but it did cause me to pause a couple of times to make sure I was connecting the right wire. Certainly not a big deal, but a bit annoying. Also, it is difficult to tell from the picture, but the entire adapter is about a foot long.

Pros: -well built -simple design

Cons: -non standard color choices may cause confusion

The only way to go if you have a deck with SW outputs on it. Pair with the kicker slim sub and you're good to go.

Pros: Easy to use

Cons: None

Does just what it s designed to do. Nice that it comes with the adapters too..

Pros: works perfect Nicely made

Cons: none

Does what it needs to do

Written by: Rich from Illinois on November 3, 2015

Crutchfield Customer Review (What's this?)

No problem with this at all, I just checked continuity on the wire color to center pin and made my appropriate connections

Pros: Very pliable wires, easy to work with.

Cons: Would be nice to have more traditional color coding rather than blue and gray, but a simple continuity check solves that easily enough.

Hate that it's needed, but it works perfectly

Crutchfield Customer Review (What's this?)

I hate that the hideaway sub has to use an adapter like this for low level inputs, but it does it's job perfectly so far.

Smaller magnets than last year's model. Bass is fair....could be better overall sound for the price.

Pros: Included crossover

Cons: Sound not up to par. for the price.

Adapter cable

Written by: mitchell from Michigan on April 27, 2015

Crutchfield Customer Review (What's this?)

the product ordered was acceptable and met all expectations.



Very good quality cables.

Written by: Steve-F from Tennessee on April 22, 2015

Crutchfield Customer Review (What's this?)

These cables are very good quality and they work great.

Pros: High quality and they look great even though they are totally hidden in my truck.

Cons: These really should have been included with the Kicker 11HS8 Hideaway compact powered subwoofer. Also, would have been nice if they used conventional red & white colors to mark the polarity of the cable ends.

Worked Perfectly !

Written by: Tim from Ohio on April 19, 2015

Crutchfield Customer Review (What's this?)

I purchased this product to hook up my new Kicker compact powered sub and they worked perfectly for it. I could not be happier than I am with my new system from Crutchfield. My system I got from Crutchfield consists of 4 Polk Audio (571 2 way) speakers, Pioneer DVD Receiver (AVH-X5700BHS DVD Receiver), Pioneer AMP (GM-A6604), Kicker Sub (11HS8 8" Compact Powered Subwoofer), & last but not least a Kicker KISL Audio Interconnect Cable. With everything I purchased from Crutchfield with the help of Kyle on my system and Buzz on my Kicker Amp and believe me, I could not have done it right without there help and got it to be like it is and sound as good as it does, what I am trying to say is it sounds "FANTASTIC" and I could not be happier..... Thank You Crutchfield, Kyle and Buzz for everything !!!

Pros: Everything

Cons: None

Does what it's suppsed to

Written by: Anonymous from Columbus oh on January 3, 2015

Crutchfield Customer Review (What's this?)

This does no signal conversion. It simply gives you a clean way to go from speaker wire to RCA.

Pros: Looks nice. Quality product.

Cons: While obvious, there are no instructions or labels on the polarity

RCA Adapter

Written by: Sam from Carson City on November 6, 2014

Crutchfield Customer Review (What's this?)

I used this adapter to run RCA from my Kicker Hideaway 8 to my head unit. Worked great, instructions could have been a little clearer. Blue is the positive side and grey negative.

Pros: Ease of install.

Cons: Better Instructions for wire Identifucation

Great Product

Crutchfield Customer Review (What's this?)

Was easy to connect, works well.

Pros: Easy to use/Connect, make sure you don't get your wiring out of phase( negative to positive ) if you have no difficulty making those type of connections this product is easy as it gets. Also the length is approx . 12" so keep that in mind.

Cons: None.

The product worked well and my sound is wonderful!

Pros: It works very well.

Cons: It wasn't automatically included with the Kicker System.


Written by: jdza from Ca on May 19, 2014

Crutchfield Customer Review (What's this?)

Did what they are supposed to do but it would be nice if the polarity on each line was labeled. Two grey wires and two blue wires. You figure out which ones go together! Not difficult but it would be nice to not have to think about it.

Pros: Gets the job done

Cons: Lack of polarity labeling

It works great with my bass station. I agree with a lot of the other reviewers that kicker should have just included it but I am happy with the product and it sounds great in my truck!

Pros: Works great

Cons: None

Didn't work for me

Written by: Dean D from Houston, TX on March 27, 2014

Crutchfield Customer Review (What's this?)

Adapter didn't work for me. Contacted Kicker support and they recommended connecting straight to the rear speaker outputs. Sub works that way so I ended up chunking the adapter in the trash.

Pros: Easy to wire

Cons: Didn't work well for me. I went straight with the rear speaker wires.

Does it's job.

Written by: XJMike from NY, USA on March 20, 2014

I bought this one to replace the previous model which is discontinued. I don't like how it lacks the previous model's speaker wire connector (it felt solid, and looked super clean), but it does it's job, and my 11PT8 bass station is back to producing bass again.


Cons: Doesn't have the speaker wire connector like the previous model.

Must Have!

Crutchfield Customer Review (What's this?)

Wish Kicker would just add this cable in when you buy the Subwoofer! Does what it needs to do!


Cons: Kicker needs to add this to the Hideaway!

Crutchfield Customer Review (What's this?)

easy to wire in . just pay attention to your connection as not to get out of phase . still easy fix w/built in phase switch in box....Kicker PT 8

Pros: well built product

Cons: should come w/ pos. and neg. tags but not hard to figure out

Neccessary if you are using RCA pre-amps

Written by: Rkrause63 from Sandy, Utah on July 7, 2013

Crutchfield Customer Review (What's this?)

Not a whole lot to say on these. They work fine. IF you are setting up your system using the pre-amp output of your head unit, you are going to need these as the Kicker Hideaway sub only has line level connections. also remember to switch the sub to low level input if you are sending the signal to the sub from the sub pre-amp outputs of your headunit.

Pros: they work fine & the construction is solid

Cons: Any powered sub from a reputable manufacturer should have low level RCA inputs build into it. Having to actually buy these separate is pretty CHEESY!

Why did you buy this?

To wire a powered subwoofer purchased a month ago on Crutchfield's website. [ Michel  Feb 02, 2016 ]
Your recommendation for the Kicker Hideaway sub [ James  Jan 19, 2016 ]
Routing a stock stereo to an amplifier using the speaker level inputs. This seemed to be the simplest way to go. In the past, you'd have to buy an entirely separate crossover module to do the exact same thing. [ Russell  Dec 29, 2015 ]
The kicker subwoofer and amp are both very high rated, the whole set up was easy to find and it looks good too [ Jeremy  Dec 24, 2015 ]
Exactly what I needed. Great bass sound for the cab of my truck. Compact. It fits perfectly under the passenger seat of my 2004 Toyota Tundra access cab. [ Paul  Dec 18, 2015 ]
Needed part to complete stereo installation on older RV. This adaptor should have been included with subwoofer purchase, I'm not happy about having to spend this extra money after making the purchase! Kicker should carry accessories for their products. [ Jeanne  Dec 15, 2015 ]
Need it to hook my Fosgate Prime amp an Punch sub up to existing Bose system in my 07 Maxima [ James  Dec 14, 2015 ]
Just purchased the Kicker Hideaway for my Subaru, advisor recommended this adapter to connect the sub to my head unit. [ Max  Dec 06, 2015 ]

I tested with an L.E.D. and a battery, an L.E.D. will only light when positive and negative are connected correctly. The blue wire is the prong and grey the ring. The blue is the signal (+) and grey the shield (-). [ Ed  Oct 18, 2015 ]
doesn't matter due to the faze switch on sub, can change the polarity.but both do need to be wired the same.If their is a black line on each set then use it as neg. and other as poss. if sub. doesn't sound right turn sys vol. down and switch faze switch should improve. [ TERRY A  Jan 13, 2014 ]
Negative-black [ JEFF  Jan 13, 2014 ]
I use the blue as positive. You can use either as long as you are consistent Always positive to positive between devices urging the color as positive makes it easier to remember. Good luck [ HOWARD  Jan 13, 2014 ]
The common color on each plug is the negative{-}. Obviously the different colors on each plug are the positive{+}. I only know this because I had to ohm them out for myself. It would be nice if they were marked - & +. [ RANDALL  Jan 13, 2014 ]
Usually the wire with the black stripe is neg [ HAROLD  Jan 13, 2014 ]
I used the blue as the positive connection. [ MIKE  Jan 13, 2014 ]
