Perfect Application

Crutchfield Customer Review (What's this?)

I needed two analog stereo inputs to two different receivers from a single analog stereo output - the Monster Cable Y adapters worked perfectly. The Crutchfield customer service rep showed me the way.

Pros: Works with no adverse sound affects. Well made ,too.

Cons: None

It works!

Crutchfield Customer Review (What's this?)

It works just as it is supposed to work. My Definitive sub was not turning on when I was using the LFE input. Now, using this Monster adapter, I am using it to connect the L and R inputs on the sub and the sub turns on when it should (it is now receiving a stronger signal).

Pros: It works (and can provide a stronger signal to the sub versus a single RCA connector) Price was great and with free shipping (and fast, too!)

Cons: Crutchfield overpacked my item in a fairly large box with lots of packing material - not necessary and rather wasteful!

It is a bargain

Written By Pablo, Miami, FL on Tuesday, June 03, 2014

Crutchfield Customer Review (What's this?)

It's really amazing, I can have all the benefits offer this ADAPTER, for this low price.

I have a Polk Audio subwoofer has dual stereo input on the back and this adapter works perfectly between my sub and my Onkyo receiver.

Congratulations MONSTER people

Pros: Excellent quality construction Easy to connect Good bass response

Cons: None

Works fine, but not needed.

Works well w/ my slightly older (front-firing) BA Subwoofer

Written By James, Littleton, MA on Tuesday, October 20, 2009

I have a slighly older (front-firing) Boston Acoustics Subwoofer with 2 RCA channel ports
in the rear. In order to capture all of the base produced by the subwoofer, I need to
reduce the 2-channel output to one. While my subwoofer does work w/o this adapter,
there's about a 30% loss of base. This Y-Adapter by Monster does what its supposed to
do and the result is earth-shattering base. I recomend this adapter for those w/ older
subs, but if you have a newer sub w/ a single channel output, you don't need it. Also,
other Y-Adapters I've tried are either cheaply made or are the cable is so thick, the
adapter doesn't flex. This Y-Adapter suffers from neither cheapness nor inflexibility. It's
perfect , for forward-firing or down-firing subwoofers.

Not Needed for Subwoofer

Written By Rob, Chicago, IL on Saturday, April 11, 2009

Crutchfield Customer Review (What's this?)

This product works just fine, but make sure you actually need it before you buy. Buying this adapter was a waste of money for me. Although not labeled with a L/MONO input, my powered subwoofer doesn't require separate left and right inputs to work properly. You can plug a mono cable into the left input and leave the right input empty.

Written By Ken, Las Vegas, NV on Saturday, October 18, 2008

Crutchfield Customer Review (What's this?)

This was a waste of money. When I called in for advice about what I needed in the way of cables to connect the subwoofer to my receiver, I was told I needed this adapter. When I called back after trying to get the subwoofer to work, it was discovered I did not need the adapter after all.
