1 male RCA / 2 female RCA
Our take on the EFX Y-adapter by Crutchfield's Tim Sprinkle
This Y-adapter from EFX consists of 1 male and 2 female RCA plugs handy for splitting one channel into two. Length: 4". Warranty: 1 year.
I needed 2 of these adapters that were short enough for the back of my after market radio. My vehicle has tight space that excess wire wouldn't allow a proper fit. This length was the only one i found that was just the right size i needed.

Why did you buy this?
I purchased this item because my aftermarket radio only takes 1 pair of rca (2 channel) & I have a 4 channel amp which needs 2 pairs rca inputs (4 channel). [ Robinson Feb 27, 2016 ]

That's what I used them for. Bought them to turn 1 into 2 per connection for a newer 4 channel amp I installed. [ richie Feb 28, 2016 ]
